These bees are on the move.

Credit: Tracey Samuelson/Marketplace "As soon as you get on the freeway and there’s air flowing past the entrances, all the bees run back inside,” says Lewis, of any stragglers.

Lewis, who runs Bill’s Bees, is taking about 700 of his hives on a road trip to the California’s Central Valley, where he’ll unload them across acres of almond orchards, working until 1 or 2 a.m. under the light of full moon.

All across the country, more than a million-and-a-half colonies are making a similar journey – traveling hundreds or even thousands of miles to pollinate California’s almonds. Farmers rent hives for few weeks because in order for almond trees to produce nuts, bees need to move pollen from one tree to another. 

No bees, no almonds.

“This pollination season there will be [some] 800,000 acres of almonds that need to be pollinated,” says Eric Mussen, a honey bee specialist at the University of California Davis. He says more than 100 different kinds of crops need these rent-a-bees, but almonds are significant for the number of acres that require pollination all at the same time. About 85 percent of the commercial bees in United States – which Mussen calls “bees on wheels” – travel to California for almonds.

The state supplies roughly 80 percent of the world’s almonds, worth $6.4 billion during the 2013-2014 season, according to the Almond Board of California.

“It’s a matter of numbers,” he says. “You’re trying to provide enough bees to be moving the pollen around between the varieties and whatnot. It’s just a huge, huge number of bees. The only way we can get a huge number of bees in one place at one time is to bring them in on trucks.”

In fact, bees are such an important part of the almond business that Paramount Farms, one of the biggest almond growers in the world, has decided they need to be in the bee business, too. The company just bought one of the largest beekeepers in the United States, based in Florida.

“Bees are so essential for the process of growing almonds,” says Joe MacIlvane, Paramount’s president. “If we don’t have a reliable supply of good strong colonies, we simply won’t be a viable almond grower, so that’s our primary motivation for getting into the business.”

Renting bees is about 10 to 15 percent of Paramount’s production costs, but the motivation to keep their own bees isn’t simply economic.

“Many bee keepers are individual or family business and many people are getting on in years and we don’t see a lot of young people coming into the business,” says MacIlvane.

Additionally, bee populations are struggling. A significant number having been dying each year for the past decade or so, thanks to a mix of factors, from pesticides to lost habitat for feeding. Sometimes it’s difficult to know exactly what’s killing them.

“We had a large problem last year with bees dying in the orchard because of something that was going on during bloom,” says Bill Lewis. He thinks a pesticide or fungicide may have been to blame.

This year, Lewis and his bee broker are being pickier about the farms they’re working with, vetting them more carefully because those lost bees had big economic consequences – about $300,000 in lost income for Lewis."

Almond Growers Assess Impact of Freeze

California Farm Bureau Federation - Ag Alert     By Kevin Hecteman     February 28, 2018

Steve Van Duyn looked around an almond orchard he manages southeast of Galt on a chilly morning, surveying the effects of California's weeklong run of freezing weather. Several nights with temperatures dropping below freezing have Van Duyn and other growers concerned about their crops.

"We've sustained some damage," he said. "The full extent, we won't know for quite some time. In a few weeks, we'll know—we'll have a better guess—but we really won't know till harvest time."

Van Duyn said he'd been irrigating orchards each morning, to help warm the blossoming trees as much as possible. The deep freeze that struck the Sacramento and San Joaquin valleys had many growers pulling all-nighters, trying to save their crops.

"It was unprecedented for just a number of years, as long as I can remember, that we were up every night, Monday through Friday night," said Ripon-based almond farmer David Phippen.

Mel Machado, director of member relations for the Blue Diamond Growers almond marketing cooperative, said reports from Glenn to Kern counties showed temperatures as low as the mid-20s, with many areas dropping to 31 to 33.

Though Machado and others can put numbers on the temperatures, they can't do the same to the 2018 almond crop just yet.

"Long story short, I can't walk into my brother's marketing office and say, 'Here's what the crop's going to be,'" Phippen said.

Reports of damage vary widely.

"Because of the stage of (bloom) development, because of whether you have water or not to apply, we will see fields that are virtually untouched adjacent to ones that are severely damaged," Machado said. "It's going to be that variable, and it's going to make it that much more difficult to really figure it out."

California farmers harvested 2.1 billion pounds of almonds on 940,000 bearing acres during the 2016-17 season, according to the Almond Board of California. The objective forecast for 2017-18 calls for close to 2.3 billion pounds.

The cold snap resulted from a shift in the weather pattern, said Jeff Barlow, a meteorologist in the Hanford office of the National Weather Service, who said weather systems had been "coming out of the Gulf of Alaska and dropping south across the Pacific Northwest and sliding into Northern California, and then coming across the Central California interior."

At the orchard Van Duyn manages near Galt—one of the almond, walnut and winegrape operations he oversees in San Joaquin and Stanislaus counties—he said the third-leaf Independence trees produce 400-500 pounds per acre in a good year.

"So if we come in with a crop of between 400-500, I'd say we had negligible damage," Van Duyn said. "If we come in at 200-250, I'd say we had a 50 percent crop reduction."

Van Duyn found damaged blossoms in the orchard, but also found many that survived the freeze intact.

"Every morning, we're up here running the water from about anywhere from 10 o'clock at night to 2 in the morning starts, and running them all the way till 9 o'clock, 9:30 before it warms up," Van Duyn said.

That water is a crucial factor, said David Doll, a University of California Cooperative Extension farm advisor in Merced County.

"Most farmers rely on the use of water applications at a rate of 30 gallons per acre per minute," Doll said. "This will warm the orchard by 2-3 degrees, depending on the dew point and temperature. Farmers can also use wind machines, but this isn't as common" in almonds, he added.

Phippen said he's seen no crop damage so far around Ripon and Manteca, but orchards near Oakdale and Waterford weren't as fortunate. One 20-acre parcel owned and farmed by his son-in-law suffered severe damage, he said. Phippen added that he's guardedly optimistic about his crop, thanks in large part to the warm weather that set off the bloom earlier than usual.

"We've never had this much frost, so that would tell you this isn't stellar," he said, "but the bloom has been one of the nicest blooms I've ever seen. There's been a long dwell on the bloom. The concurrent pollination from one variety to the other has overlapped beautifully. We've had a lot of bee flight hours. There's not a lot to be said negative about the bloom period that we've had. It's just that we had this frost along with it."

Phippen said he thinks he'll know by the first of May how the harvest will shape up.

An almond tree's vulnerability to frost will depend on a number of factors, Doll said.

"As the tree progresses through bloom and into nut development, it becomes more sensitive to frost conditions," Doll said. "For example, the critical temperature at pink bud (beginning of bloom) is 25 degrees; at full bloom, it is 26 degrees; and at nutlet stage, it is 28 degrees. Extended periods at or below this temperature (greater than 30 minutes) will lead to crop loss."

Citrus growers in the southern San Joaquin Valley used wind machines and irrigation to fight the chill, according to California Citrus Mutual. With nearly half of this season's crop already harvested, growers were aiming to protect next year's crop, as the warmer temperatures earlier in the month caused the bloom to arrive early.

"The coming days will reveal if damage was incurred," Citrus Mutual said. "Growers are optimistic that if there is damage, the trees will have ample time to bounce back and push out another set of blooms this spring."

Warmer temperatures could reach the Central Valley this week, Barlow said, as two weather systems reach California.

"We are looking at anywhere from a half to 1 inch of rain in the valley, and then 1 to 2 feet of snow up in the high Sierra," Barlow said. "Then we go back to a warm and dry pattern for the weekend and into early next week."

Average high temperatures at this time of year, he said, would be in the low to mid-60s.

Average, of course, doesn't describe a year in which spring-like, short-sleeve weather was followed immediately by the forceful return of Jack Frost.

"My dad is almost 84 years old," Van Duyn said. "He doesn't recall a year like this."

A Bee Mogul Confronts the Crisis in His Fields

The New York Times    By Stephanie Strom     February 16, 2017

Beekeeping on an industrial scale is central to American agriculture,
and “colony collapse” has proved to be a severe test.

KERN COUNTY, Calif. — A soft light was just beginning to outline the Tejon Hills as Bret Adee counted rows of wizened almond trees under his breath.

He placed a small white flag at the end of every 16th row to show his employees where they should place his beehives. Every so often, he fingered the buds on the trees. “It won’t be long,” he said.

Mr. Adee (pronounced Ay-Dee) is America’s largest beekeeper, and this is his busy season. Some 92,000 hives had to be deployed before those buds burst into blossom so that his bees could get to the crucial work of pollination.

But it is notable that he has a business at all. For the last decade, a mysterious plague has killed billions of bees every year.

“Every year at this time of year, we wonder are there going to be enough bees,” said Bob Curtis, director of agricultural affairs at the Almond Board, a trade group for almond growers.

Pollination services, as the bees’ work is known in the industry, has risen this year to between $180 to $200 a hive from an average of $154 a hive in 2006, Mr. Curtis said.

There would be no almond crop — not to mention avocados, apples, cherries and alfalfa — without honeybees. Of the 100 crops that account for 90 percent of the food eaten around the globe, 71 rely on bee pollination, according to the United Nations Food and Agriculture Organization.

commercial beekeeper as he ships his bees across California for almond season.

Demand for Mr. Adee’s bees is soaring in part because a poorly understood plague, known as colony collapse, has decimated the nation’s bee population in the last decade. The cause is widely debated: Some cite climate change affecting habitat, others the proliferation of certain pesticides, but most believe the problem has multiple factors.

Whatever the reason, in the year that ended in April 2016, 44 percent of the overall commercial bee population died. In a typical year before the plague, only 10 percent to 15 percent would have died, and Mr. Adee’s losses would have been between 3 and 7 percent.

“Over the last five years, I think this small industry could easily have lost $1.2 billion worth of bees,” Mr. Adee said. To put that in context: The total United States commercial bee business had a value of only about $500 million in 2012, according to the Honey Bee Advisory Council, created by Monsanto in 2012 to study its impact on bee health.

Nor is the problem limited to honeybees. The bumblebee was scheduled to be listed under the Endangered Species Act on Feb. 10, but the Trump administration put the plan aside, pending further review. The E.P.A. has not responded to requests for comment.

This is pollination season for America’s almond trees. As a result, in recent weeks almost two-thirds of the country’s commercial bees have started buzzing through California’s orchards. Some of the bees have been shipped in from as far away as Florida.

Adee Honey Farms has some 92,000 hives, each with roughly 40,000 bees, about 3.5 billion bees in total. Most spend the winter here in hives scattered across a 3,000-acre cattle ranch surrounded by low hills with easy access to water, a necessity for such a concentrated population.

During pollination season, the bees are loaded onto a dozen flatbed trucks and nine or 10 tractor-trailers and ferried to work, starting first in the almond orchards in late January, then moving to other California crops like broccoli and avocados. About 10 percent of the Adee bees are dispatched to Oregon and Washington State, where they pollinate cherry and apple trees.

They work until early May, when the trucks take them to the Midwest for the summer.

Like other commercial beekeepers struggling with the population decline, Mr. Adee has stayed afloat, in part, by acquiring the colonies of other beekeepers: The number of commercial beekeepers (those with more than 300 hives) has dropped, though no one is certain by how many.

He has also been forced to split his colonies to rebuild his stocks, a process that entails moving some bees out of one colony and fooling them into building colonies around new queens.

Nonetheless, his losses were so high last year that he had to borrow bees to fulfill his contracts. This year, thanks in part to the acquisition another beekeeper’s business, he had bees still waiting for work as he deployed his hives across California in late January.

He attributes this year’s relative good fortune to the decline last summer of soy aphids, a tiny, translucent, invasive insect from Asia that devastates soybean crops in America. Fewer of the pests meant that many soybean farmers in South Dakota delivered only one application of the pesticide known as neonicotinoids, Mr. Adee said, and the spraying occurred before the arrival of his bees. (Adee bees spend the summer in North and South Dakota, Nebraska and Minnesota, and Kelvin Adee raises queen bees in Texas and Mississippi.)

Neonicotinoids are a class of insecticides that are widely used to kill off aphids and other bugs. Some studies tie them to the declining health of bees and a drop in the populations of birds that depend on those insects for food. In 2013, the European Union and several countries in other areas placed limits on the use of those insecticides.

“The more you study it, the more obvious it becomes: the relationship between the pesticides that have been sprayed everywhere over the last 10 years and what’s happening to bees,” Mr. Adee said.

Not that he blames any one thing for the problem. Rather, it is that comprehensive research is rarely done, which, he said, would implicate a variety of factors.

James Frazier, a bee expert at Pennsylvania State University, agreed. The bee shortage has to do with the overall health of bees, and not one or two specific things. Bees are exposed to a variety of pesticides, all of which can affect their immune systems, he said. That in turn makes them less resistant to diseases and parasites carried by the varroa mite and enables the spread of viruses.

“It’s more complicated than trying to cure cancer,” Dr. Frazier said, “because bees are outside, where you have all these uncontrollable things working on them.

Bees from one keeper are mixing with those from other populations as their numbers fall. That may aid in the spread of diseases and parasites, said Ann Bartuska, the acting under secretary for research, education and economics at the Agriculture Department.

“There is no smoking gun,” Dr. Bartuska said. “We still are trying to tease out what combination of factors really leads to beehive health declines.”

Adee Honey Farms was started by Vernon Adee, Mr. Adee’s grandfather, during the Great Depression after he received a letter from his brother in Missouri that read: “I can’t sell chickens or hogs, but I’m doing well with honey. Be advised: Get a beehive.”

Vernon Adee and his son, Richard, raised bees for honey production only. But as that business began to suffer from competition from Chinese and Latin American honey producers, Bret Adee and his brother Kelvin, sons of Richard Adee, figured they needed to develop another business to keep the company afloat.

So in 1990, Bret Adee and his wife, Connie, packed their two children (they now have four) into a truck loaded with beehives and moved to Bakersfield, Calif. Today, the pollination business provides two-thirds of the company’s revenue and all of its profits, Mr. Adee said.

Because of imported honey, “There’s no money in honey any more,” he said. Nonetheless, his daughter Elizabeth has started selling the family’s honey in farmers’ markets, a tactic she hopes will help revive that portion of the business.

When the Adees arrived in Bakersfield in 1990, there were 411,000 acres of farmland planted with almond trees, according to the Agriculture Department. Since then, the number of acres of almond trees has more than doubled, and growers have adopted techniques that are less bee-friendly.

Growers previously flooded their orchards with warm water in the early spring to prevent frost from killing the buds. The water gave rise to grasses and weeds like dandelions and wild vetch between the rows of trees, giving the bees a source of pollen before the buds burst into bloom.

But now, growers aim to conserve water, and because weeds and grasses can trap cool air that can lead to frost, most almond ranchers spray herbicides to keep the rows between their trees free of unwanted growth.

To safeguard his bees, Mr. Adee’s employees lay a pad made of yeast, sugar and other nutrients under the lid of a hive to give the bees something to eat before the trees bloom.

He also scouts out areas close to uncultivated land or grazing areas with water nearby. His bees spent last fall and early winter in hives scattered about a ranch ringed by the foothills of the Diablo Range and close to aqueducts and other water sources. “They’re far away from anything bad for them,” he said.

At the ranch, cattle lazily grazed in the evening amid neatly stacked clusters of hives, looking on curiously when flatbed trucks pulled into load the bees for overnight journeys.

The deployment of bees resembles a military operation, with Mr. Adee serving as its commander. Hives must be loaded onto trucks in the evening, four hives at a time on pallets precariously balanced on a forklift. Each truck transports 216 hives over dirt roads that, thanks to this season’s rain, were deeply rutted and thick with mud.

The Adee bees rent for $200 a hive. On average, Mr. Adee places two hives per acre of almond trees. A 4,500-acre almond orchard would require about 9,000 hives, although growers are free to specify the number of hives they want.

Commercial beekeepers are a tight-knit group, and most new contracts come as referrals from other beekeepers and clients. “It’s kind of like a grapevine,” Mr. Adee said. “If you have to advertise, then you’re not much of a beekeeper.”

During pollination season, he typically leaves home at 5:30 a.m. and heads for an orchard or field to map the day’s plan. He relies on two thermoses of coffee to keep him going.

Placing flags to mark the spots in orchards where hives are to be placed gives Mr. Adee a chance to survey the terrain. If a row of trees happens to have a low spot, he will place a flag a few rows away to ensure the hives do not stand in water. If his pickup slips in the mud, he makes a call to warn drivers not to take their much heavier equipment down the same path.

Mr. Adee marks plot maps with neon Sharpies, using a different color to indicate which crew is to deliver which bees to a particular spot.

After setting his crews in action — roughly 100 employees during pollination season, Mr. Adee then makes a second and sometimes a third round of deliveries to orchards, stopping occasionally to right a hive or gently squeeze the tips of branches to gauge when they might bud. He then has an idea when his bees might need to be fed again.

Hives look like small white dots on ranchland outside Bakersfield, Calif. Demand for pollination services has increased as a mysterious plague known as colony collapse has decimated the
nation’s bee population over the last decade.

Between stops, he talks on the phone — when his cell gets a signal, that is. In one call, he spoke to his foreman about two trucks needing repair.

Then he called an independent trucker to see if he could move bees that night, diplomatically sidestepping the man’s request that he also hire a friend. “Well, I won’t know until tonight what’s needed,” Mr. Adee said.

After that, he called a lawyer, seeking counsel for a beekeeper who had lost his bees after the ranch across the street sprayed an organic phosphate. “It was an illegal application, and the county knows it,” he said. “But the county is dragging its feet. He needs some help.”

In 2006, David Hackenberg, another beekeeper with a large bee collection, lost 90 percent of them and coined the term colony collapse. Mr. Adee had no such problem that year. I in the documentary made that year, “The Vanishing of the Bees,” he can be heard saying,“We haven’t seen any of this colony-collapse disorder here.”

Shortly after the film came out, though, he also lost almost all the family’s bees.

“Still, I was convinced my problem was a virus, not what David had,” Mr. Adee said. “I thought it would take three years for it to run its course, and then we’d be done with it.”

But the losses stretched on, into a fourth and then fifth year. Last year, after having lost roughly half of his 90,000 hives, he joined Mr. Hackenberg, other beekeepers and environmental groups in a lawsuit against the Environmental Protection Agency.

The suit contends that the E.P.A. broke the law by failing to require registration of seeds coated in pesticides, as many genetically engineered seeds are. “E.P.A.’s actions and inactions have caused both acute honeybee kills and chronic effects leading to excess bee colony mortality, excess bird mortality, nationwide water and soil contamination, and other environmental and economic harms,” the plaintiffs argued.

There is no federal insurance program to cover beekeepers. The federal 2008 Farm Bill did allocate $50 million in emergency assistance to cover losses in livestock, farm-raised fish and honeybees, but only through 2011.

A year later, the Agriculture Department estimated that beekeepers had spent $2 billion to replace the 10 million hives they had lost in the six years since bee colonies first began experiencing declines.

Here, the almond trees are just beginning to bloom. Mr. Adee’s bees work alongside their boss, who is working the phones.

Someone on the phone asked him to address a matter that had nothing to do with his bees. “I don’t know that I have time for that,” Mr. Adee said. “Or rather, I know I don’t have time.”

Precision Spray Pollination Would Negate Problems Such As Not Having Enough Honey Bees, Distribution of Pollen-borne Viruses and Insufficient Pollen Distribution

CATCH THE BUZZ      February 2, 2017

WENATCHEE, Wash. — Spray pollination may someday replace bees in orchards, withholding irrigation before cherry harvest doesn’t do much and adding hand pruning to mechanical pruning every other year boosts yields.

That’s what Matthew Whiting, Washington State University plant physiologist, told growers at the Northcentral Washington Stone Fruit Day in Wenatchee on Jan. 17.

Precision spray pollination would negate problems such as not having enough honeybees, distribution of pollen-borne viruses and insufficient pollen distribution, Whiting said.

Pure pollen can be kept alive in a liquid state for two hours without loss of germinability, he said.

“We are pursuing this further. We are using an electrostatic sprayer for 12 to 14 gallons per acre. Electrostatic because the (flower) stigma has a negative charge,” he said.

For years, growers have debated whether withholding irrigation a week or two before harvest yields better cherries. Whiting said two years of studies led him to conclude “it’s a much ado about nothing.”

While recognizing there are many variables — including soil depth and type, genotype of the cultivar and rootstock and types of irrigation systems — Whiting set up trials withholding water from seven to 17 days before harvest and found no effect on bud density, bloom, firmness, cracking, size or quality.

Soil moisture dropped but trees showed no significant stress, he said.

The only potential benefit was a 2 percent increase in soluble solids, mostly sugar, which could be tasted but only with Lapins and not Chelans, he said. In one case, soluble solids increased 10 to 13 percent and firmness dropped about 6 percent, he said.

Mechanical pruning of planar or fruiting-wall style orchards saves labor and can save 20 percent or more in annual production costs and improve worker safety and efficiency, Whiting said.

Powered by tractors, mechanical pruners hedge the sides of trees and top them. There are more ragged cuts and only half as much wood is removed so a good plan is to remove more wood by following mechanical pruning with hand pruning every other year, he said.

Mechanical pruning is 23 to 29 percent faster than hand pruning. Mechanical combined with hand pruning is 66 percent more efficient than hand pruning alone, he said.

Fruit weight is slightly smaller with mechanical pruning but yield is greater because more wood and more buds are left, he said.

Hand pruning cherry trees costs an estimated $741 per acre versus $168 for mechanical only and $590 for a combination, he said.

Bees Are Back Pollinating The Almonds

BugSquad By Kathy Keatley Garvey     February 10, 2017

It's almond pollination season in California but the weather refuses to cooperate.

Heavy rains, high winds, intense flooding. What are the bees to do?

They're holed up in their hives, waiting for the sun breaks. When the rain stops pelting their hives and the temperature climbs to 50 or 55 degrees, they poke their heads out. Let's go, girls!

Such was the scenario today when we went for a drive along Pleasants Valley Road in Vacaville, Solano County. Feral almond trees, storm-battered but stubbornly bracing for more, are blooming, and those bees--those glorious bees--are back.

The statistics are a bit overwhelming. California now has one million commercial acres of almonds. It takes two colonies per acre to pollinate them. Without bees, no almonds. With beekeepers reporting winter losses of 40 to 60 percent, what's the situation?

"What does that mean for the bee supply for almond pollination?" asks pollination guru Gordon Wardell in the current edition of Project Apis m (PAm). The organization's name comes from Apis mellifera, the scientific name for the European honey bee. "At present, while individual beekeepers' numbers appear to be down, there doesn't appear to be a shortage of colonies for almond pollination this year.  While the supply might be tight, I don't foresee major shortages.  Rental prices are up this year, averaging $170 to $185 per colony.  This is $10 to $15 over rental prices last year.  These prices are fair increases considering the amount of feeding needed to ready the colonies for February pollination and the increases in transportation costs."

Wardell, chair of PAm's board of directors and the 2016 recipient of the California State Beekeepers' Association's Distinguished Service Award, knows bees, knows almonds, and knows pollination.  A professional apiculturist for more than three decades and now director of pollination operations for Wonderful Orchards, he's a former Extension apiculturist for the state of Maryland. His research includes developing Mega-Bee, the honey bee nutritional supplement. He's authored numerous publications on honey bees. His expertise covers Varroa mite control, honey bee nutrition, fire ant monitoring, small hive beetle, Africanized honey bees, and many other topics.

Wardell describes what's happening in California now as "the greatest commercial pollination event in the world."

Because it is. Billions of bees pollinating a million acres of almonds.

On a minuscule scale, it's still marvelous to see a dozen bees foraging on a single feral almond tree...doing what bees do.

California Almond Forecast Increases

CATCH THE BUZZ    By Carlos Nunez/Fresh Plaza    July 18, 2016

The latest almond crop forecast for California has this year’s almond production up over last year’s production by almost eight percent. The objective measurement report, which was released on Wednesday, has this year’s crop bigger than what was estimated in the subjective report released in May.

According to a survey conducted by the USDA’s National Agricultural Statistics Service, California’s 2016 almond production is forecast at 2.05 billion meat pounds – that would make it 7.9 percent larger than last year’s crop.

The objective reported noted good bloom conditions, and the bloom period was characterized as fast and uniform. Compared to the previous season’s winter, this most recent winter was better for the almond crop in terms of chill hours and precipitation. Though many areas are still suffering from lingering water shortages, trees have been recovering from drought conditions.

Beekeepers Prepare For Pollination

appealdemocrat.com    By Chris Kaufman    January 26, 2016

Philip Russell, left, with fellow beekeepers from Strachan Apiaries, take inventory of
their bees on Tuesday, January 26, 2016 at a holding area in Yuba County.

In the coming months, millions of bees will be deployed to help pollinate orchards.

"There is a lot of doom and gloom in the industry right now with unexplained bee colony losses, drought, varroa mites, viruses and dropping honey prices," said Philip Russell, with Strachan Apiaries in Yuba City. "I guess the bright spot would be that we are still here and so are the bees." 

Russell, who was out with a crew on Tuesday taking inventory of some of their estimated 11,000 bees, said there are other positive notes.

"There's also becoming more awareness about the plight of the bees and other pollinators," Russell said. "This awareness has reached all the way up to the president, who set certain policies in order to ensure cooperation between government entities and beekeepers."

According to the White House website, honey bee pollination adds more than $15 billion in value to agricultural crops each year and in 2014 the president established a Federal Strategy to Promote the Health of Honey Bees and Other Pollinators.

Lynn Kimsey, professor of entomology at UC Davis, detailed some of the issues surrounding honeybees and the substantial role they play in agriculture.

"There's a problem with nutrition. There are long periods of time in the summer when there's nothing for them to eat," said Kimsey, who is also the director of the R. M. Bohart Museum of Entomology. "Sugar water doesn't have the nutrients needed, and it's especially a problem for baby bees."

She said mites and the diseases transmitted by mites are also problematic. The pesticides and the miticides used to control the mites can negatively affect bees.

Russell said awareness about the plight has brought a boom to smaller operations and hobbyist beekeepers but even that has a downside.

"They don't always know the rules and regulations that have been followed by beekeepers for years or even those set forth by each county ag commissioner," Russell said. "These include a spacing minimum of a mile from other beekeeper locations that are already established, registering your hives and locations with the county."

Russell said that ensures smaller operations and hobbyist beekeepers who don't treat their bees for pests or diseases will not infect neighboring hives.

"Commercial beekeepers are aging out, and it's hard work," said Kimsey, who added the average age is about 60. "There's a big push to have hobbyist beekeepers, which is good but not enough to handle all the commercial operations."

Kimsey said in the coming months, growers will have to import 1.5 million colonies, and with 30,000 to 50,000 per colony, that's a lot of bees.

"The number is huge and they simply can't keep enough healthy bees in California," Kimsey said. "Moving the bees, especially along bumpy roads, can also stress them."

Russell said most of their business is within the surrounding counties, but they have clients as far south as Fresno.

"Locally, we use them on almonds, prunes, and crops used for seed like melons, sunflowers, squash, pumpkins, onions, carrots, cilantro and alfalfa," said Russell. "People also use them in Washington and Oregon for apples and cherries."

California Almonds Have Smaller Impact Than Many Foods

Yale Environment 360   July 21, 2015

California almonds could become carbon-neutral or even carbon-negative if growers were to make full use of practices such as shell, hull, and biomass recycling, according to new research in the Journal of Industrial Ecology. Eighty percent of the world's almonds come from the drought-stricken state, and production operations there have drawn much ire since studies showed that almonds are a particularly water-intensive crop. However, the new research shows that the energy and greenhouse gas footprints of almonds can be lessened by, for example, using shells, hulls, and orchard biomass to generate electricity or feed dairy cows. Soils and woody biomass in almond orchards also temporarily store carbon, and when this is taken into account, their greenhouse gas footprint may be reduced by an additional 18 percent, the researchers say. "Our research shows 1 kilogram of California almonds typically results in less than 1 kilogram of CO2 emissions," said author Alissa Kendall, which is "a lower carbon footprint than many other nutrient- and energy-dense foods."

Almond Prices Surge as Sales Boom Collides With Drought

Bloomberg News   By Leslie Patton  July 5, 2015

The almond is having its moment.

Though criticized for being a water-thirsty crop grown mostly in California, almonds are more popular than ever. And spreads made from the tree nut are increasingly supplanting peanut butter in U.S. lunch boxes and pantries. Americans are eating about 2 pounds of almonds per person annually, double the amount they consumed just seven years ago.

Protein-rich Paleo diets, peanut-butter allergies and evolving

tastes have all fueled demand. That’s sent major U.S. food makers such as Hain Celestial Group Inc. and JM Smucker Co. into the market, where they’re vying against smaller suppliers. Almond butter now comes in a range of flavors, including maple and dark chocolate.

But the almond craze has come at a cost. The growth in consumption -- coupled with smaller crops...

Commentary: We Must Communicate the Facts About Water Use

AgAlert   By Mark Jansen   May 26, 2015

The headlines have been unavoidable. Almonds have been painted as our state's "thirstiest" crop, but what these stories lack is context. The management team from the Blue Diamond Growers cooperative has been collaborating with industry experts to communicate the facts about agricultural water use to the media and our urban neighbors.

According to a recent editorial in the San Jose Mercury News, "California's dams and reservoirs were never envisioned to release water year-round for environmental objectives such as aiding the delta smelt or reintroducing salmon in the San Joaquin River watershed. A majority of reservoir water once intended for households or farming is simply sent out to sea."

Clearly, our solution to California's water situation will require a collaborative effort among all Californians to find a solution that makes sense for everyone.

The drought debate continues as we enter the hot, dry summer of the Central Valley, with mandatory water restrictions now in place throughout our state. For many Californians, that means the drought will now affect their day-to-day lives. Millions of urban Californians will have to join agriculture in the fight to save water and push for storage to protect our future. Gov. Brown's mandate made it clear that all Californians need to do their part to conserve our most precious resource, and yet the media firestorm aimed at agriculture, and almonds specifically, has been fierce.

Our message has been simple: All food takes water to grow.

California's agricultural abilities are second to none. In fact, according to the California Department of Food and Agriculture, nearly half of our country's fresh fruits, nuts and vegetables come from California. And CDFA reports that from 1967 to 2010, California agriculture has increased revenue and decreased total applied water use by 20 percent.

In order to achieve such an impressive statistic, access to a consistent water supply is key. The amount of water required for California farming to grow our food is only 40 percent of captured water, with environmental projects taking the majority at 50 percent. The often-quoted 80 percent ignores any water used for environmental purposes.

I have read suggestions that agriculture has been let off the hook by the governor's mandate. Here are the facts: In 2014, farmers received only 5 percent of their contracted State Water Project allocation and 0 percent from the federal Central Valley Project. This year, farmers are projected to receive 20 percent of State Water Project allocation and again, 0 percent of CVP water. Our farmers have been feeling the effects of this drought from the very beginning.

Some have questioned whether agriculture's economic impact justifies the amount of water used by the industry. The media points to agriculture's 2.8 percent share of the state GDP, but again, this figure lacks context. It does not tell the whole story. Getting our food from farm to fork involves an interconnected supply chain, undoubtedly contributing significantly more than 2.8 percent to the state's economy. The almond industry alone contributes 104,000 jobs to California, 97,000 of which reside in the Central Valley, and more than 37,000 additional jobs throughout the supply chain.

Speaking of almonds, there are 9 million acres of farmland in California and almonds account for 12 percent of that total, while only using 8 percent of the water currently used for agriculture. Almond crops produce more than just the kernels humans eat, which provide an efficient source of a heart-healthy, plant-based protein. The almond crop also produces hulls and shells that provide feed and bedding for livestock animals. Almonds rank No. 1 in California for food exports out of the state, with North America consuming four times more almonds than any other market. Our industry is a global driver of $11 billion in economic activity for California.

In the last 20 years, California almond growers have reduced the amount of water required to grow a pound of almonds by 33 percent. Nearly 70 percent of almond growers use micro-irrigation systems and more than 80 percent use demand-based irrigation scheduling. No one in the world can produce a high-quality almond as efficiently as we can in California.

In times of crisis, there are people who look for someone to blame. Almonds were the first target. Through sharing a few facts about our water stewardship, the media tide has turned to more balanced reporting. As the weather continues to warm into the summer, I expect agriculture will continue to field questions from our urban neighbors about water. Rest assured that Blue Diamond is committed to collaborating with our industry peers, water and environmental experts, consumer groups, regulatory bodies and policy makers to establish a water policy that makes sense for all Californians—rural and urban, Central Valley and coastal, producers and consumers.

Commercial Bees, the Unsung Heros of the Nut Business

  Marketplace   By Tracey Samuelson   March 2, 2015

 Featured in: Marketplace for Monday March 2, 2015 (Click for Link to Radio Interview)

Bill Lewis is waiting for the sun to set, the time of day when his bees crawl back inside the short white boxes that house their colonies. As the sky turns pink behind the San Gabriel mountains, on the outskirts of Los Angeles, Lewis climbs into the seat of a forklift and starts moving the hives onto the back of a flatbed truck. These bees are on the move.

 

“As soon as you get on the freeway and there’s air flowing past the entrances, all the bees run back inside,” says Lewis, of any stragglers.

Lewis, who runs Bill’s Bees, is taking about 700 of his hives on a road trip to the California’s Central Valley, where he’ll unload them across acres of almond orchards, working until 1 or 2 a.m. under the light of full moon.

All across the country, more than a million-and-a-half colonies are making a similar journey – traveling hundreds or even thousands of miles to pollinate California’s almonds. Farmers rent hives for few weeks because in order for almond trees to produce nuts, bees need to move pollen from one tree to another.

No bees, no almonds.

“This pollination season there will be [some] 800,000 acres of almonds that need to be pollinated,” says Eric Mussen, a honey bee specialist at the University of California Davis. He says more than 100 different kinds of crops need these rent-a-bees, but almonds are significant for the number of acres that require pollination all at the same time. About 85 percent of the commercial bees in United States – which Mussen calls “bees on wheels” – travel to California for almonds.

The state supplies roughly 80 percent of the world’s almonds, worth $6.4 billion during the 2013-2014 season, according to the Almond Board of California.

“It’s a matter of numbers,” he says. “You’re trying to provide enough bees to be moving the pollen around between the varieties and whatnot. It’s just a huge, huge number of bees. The only way we can get a huge number of bees in one place at one time is to bring them in on trucks.”

In fact, bees are such an important part of the almond business that Paramount Farms, one of the biggest almond growers in the world, has decided they need to be in the bee business, too. The company just bought one of the largest beekeepers in the United States, based in Florida.

“Bees are so essential for the process of growing almonds,” says Joe Joe MacIlvane, Paramount’s president. “If we don’t have a reliable supply of good strong colonies, we simply won’t be a viable almond grower, so that’s our primary motivation for getting into the business.”

Renting bees is about 10 to 15 percent of Paramount’s production costs, but the motivation to keep their own bees isn’t simply economic.

“Many bee keepers are individual or family business and many people are getting on in years and we don’t see a lot of young people coming into the business,” says MacIlvane.

Additionally, bee populations are struggling. A significant number having been dying each year for the past decade or so, thanks to a mix of factors, from pesticides to lost habitat for feeding. Sometimes it’s difficult to know exactly what’s killing them.

“We had a large problem last year with bees dying in the orchard because of something that was going on during bloom,” says Bill Lewis. He thinks a pesticide or fungicide may have been to blame.

This year, Lewis and his bee broker are being pickier about the farms they’re working with, vetting them more carefully because those lost bees had big economic consequences – about $300,000 in lost income for Lewis.

Almond Growers Consider

AgAlert    By Christine Souza   February 25, 2015

Covered in white blossoms, California almond orchards are now teeming with millions of honeybees that have been placed into orchards to pollinate the season's bloom, brought on early by sunny winter weather.

Successfully pollinating the state's 860,000 bearing acres of almonds will require an estimated 1.7 million bee colonies that come from beekeepers in California and out of state. The apiary business has experienced many challenges the past several years, including significant bee losses from the mysterious colony collapse disorder, mite problems, a lack of forage and impacts attributed to crop-protection materials applied during bloom.

To secure enough bees to pollinate its almond crop, Paramount Farming Co., a leading San Joaquin Valley almond and pistachio grower, purchased one of the largest beekeepers in the U.S., Florida-based Headwaters Farm.

"In an environment where bee supply is always in question every year, it gives us a little bit of security to have our own bees," said Gordon Wardell, Paramount director of pollination operations. "The stronger the colony, the better the pollination. In a year like this when we have a very compressed bloom, it's very important to have strong colonies to get out there and hit as many flowers as possible."

Using its own bees and bees supplied by outside beekeepers, Paramount needs more than 90,000 colonies this year to pollinate its almonds.

Almond growers managing their own bees is not new—but some have been successful, and some have not, said Ryan Cosyns of Madera County, whose family grows almonds and manages their own bees.

"The beekeeper (we had used) lost half of their hives two years in a row and notified us in January saying, 'We only have half of what you need.' This is really what spurred us to buy our own bees (in 2005), just that fear of being without bees for pollination," Cosyns said. "We got into the bee business to run our own bees, but then we inherited leased bees and some other accounts, but beekeeping wasn't really in our initial plan."

Butte County almond grower Dan Cummings, who has 10 years of apiary experience, said growers are always looking at ways to be vertically integrated, and taking care of pollination by purchasing bees is an option.

"For us in the Sacramento Valley, about one-seventh of the cost of producing a pound of almonds—a variable cost of production—is for bee rent. So, if you are inclined for vertically integrating and taking control of a critical input, bees are a natural place to look," Cummings said. "It is not only profit motivation and securing the inputs, but beekeeping is an interesting facet of a critical component of farming almonds."

Queen-bee breeder Brad Pankratz of Orland, president of the California State Beekeepers Association, said some almond growers in his area attempted to manage bees, but not always with great success.

"One of my bigger growers tried to manage his own bees, but it didn't work out and he had to rent more bees from me this year than the year before," Pankratz said. "Now, with the lack of forage and the drought, if you are not an experienced beekeeper you are really going to have a hard time with keeping bees if you don't know what you are doing."

Skilled labor is difficult to find and apiary businesses need workers who can diagnose diseases when they open a hive, which is tough, Pankratz said.

"Training guys takes a lot more than you think, for them to get it where you can send them out on their own," he said.

"Beekeeping is a tough thing to vertically integrate into," Cummings acknowledged, citing the "specialized knowledge and commitment" needed. "It is a very special individual that can do that, because beekeeping isn't easy by any stretch of the imagination."

Regarding whether more almond growers will decide to manage their own bees, Paramount's Wardell said he believes "other almond growers will watch to see how it works for us."

"Growers have tried this in the past and haven't always been successful, but there are almond growers that do own their own bees already," Wardell said. "It will be interesting to see if other almond growers do follow suit and do try to acquire their own bees."

In keeping with its other farming endeavors, the division managing bees for Paramount will be called Wonderful Bees and could market honey products, he said, although its primary focus is pollinating almonds.

Like other almond growers, Paramount has tried alternatives to reduce the number of honeybees needed, such as planting self-fertile almond trees that require fewer pollinators, and using blue orchard bees, which are being studied to work either in combination with honeybees or to even replace them.

"With the self-fertile almond, you can reduce the number of colonies in the orchard, but you still have to have a pollinator. Even then, we'd still need 45,000 colonies at one colony per acre," Wardell said. "Blue orchard bees do a great job and complement the honeybees very well, but we're having trouble getting the numbers up to do the level of pollination that we have to do."

New to pollination this season is a set of bee "best management practices," released last fall by the Almond Board of California as a guide to improve honeybee health. Practices were developed with input from almond growers, beekeepers, researchers, chemical registrants and regulators. The board described the practices as steps farmers can take with beekeepers to protect and promote bee health.

In the Central Valley orchards where Cosyns places bees, peak bloom has arrived, he said, and varieties such as Sonora have already reached petal fall.

The average price to growers for a colony guaranteed to contain eight frames of honeybees, Cosyns said, stands at about $180. The bees look good, he said, adding that he believes that after bloom there may be a little more forage this year than last year—but not enough.

"It seems there is a little more blooming in the pastures and the grape vineyards, but with the number of hives that are here, the forage pretty much evaporates," he said.

BEE Best Management Practices

Almond Board of California   October 16, 2014

As part of an ongoing commitment to honey bee health, the Almond Board of California recently released a comprehensive, set of Honey Bee Best Management Practices (BMPs) for California’s almond industry. Developed with a wide array of input from sources including the almond community, beekeepers, researchers, California and U.S. regulators, and chemical registrants, the BMPs represent the Board’s most extensive educational documents to date to ensure that almond orchards are and remain a safe and healthy place for honey bees. The documents lay out simple, practical steps that almond growers can take together with beekeepers and other pollination stakeholders to protect and promote bee health on their land and in the surrounding community.

Are Your Delicious, Healthy Almonds Killing Bees?

Mother Jones   By Tom Philpott   April 28, 2014

California dominates almond production like Saudi Arabia wishes it dominated oil. More than 80 percent of the almonds consumed on Planet Earth hail from there. Boosted by surging demand from China—overall, 70 percent of the state's output is exported—California's almond groves are expanding. The delicious nut's acreage grew 25 percent between 2006 and 2013. In a previous post, I noted how the almond boom is helping fuel a potentially disastrous water-pumping frenzy in a drought-stricken state.

Now comes more unsettling news: California's almond groves are being blamed for a large recent honeybee die-off.

What do almond trees have to do with honeybees? It turns out that when you grow almond trees in vast monocrops, pollination from wild insects doesn't do the trick. Each spring, it takes 1.6 million honeybee hives to pollinate the crop—about a million of which must be trucked in from out of state. Altogether, the crop requires the presence of a jaw-dropping 60 percent of the managed honeybees in the entire country, the US Department of Agricultural reports.

A mutual dependence has arisen between the state's almond growers and the nation's apiaries. For the 1,500 beekeepers who deliver "pollination services" to the almond industry each year, the gig provides 60 percent of their annual income—more lucrative, in other words, than selling the honey they produce, reportsthe Bakersfield Californian, a newspaper in the heart of almond country. "Without the almond industry, the bee industry wouldn't exist," one large-scale beekeeper told the paper in February.

But this year, something has gone wrong. According to the Pollinator Stewardship Council, somewhere between 15 percent and 25 percent of the beehives in almond groves suffered "severe" damage during the bloom, ranging from complete hive collapse to dead and deformed brood (the next generation of bees incubating in the hive).

Eric Mussen, a bee expert at the University of California-Davis since 1976, told me that there have been isolated die-offs on recent years, but this year's troubles have been "much more widespread…the worst we've ever seen."

The Pollinator Stewardship Council blames the cocktail of pesticides—insecticides and fungicides—almond growers use to keep their crops humming, and Mussen thinks the group may have a point.

He told me that several years ago, beekeepers in almond-heavy Glenn County began having problems keeping their brood alive, as well as with developing new queens. They began to fear that the trouble came from a widely used fungicide called Pristine, marketed by the German chemical giant BASF, for almonds. The company, which claims Pristine is harmless to bees, sent representatives to the county to collect almond pollen samples. In them, Mussen told me, they found "significant" levels of an insecticide called diflubenzuron. (Here's a copy of an email from January 2013 that Mussen circulated on the topic.) The catch is that its maker, Chemtura, insists that diflubenzuron, too, is harmless to bees.

If the two pesticides are safe for bees on their own, what's the problem? Mussen says that almond growers are combining them along with substances called adjuvants—which are used to enhance the performance of pesticides—and then spraying the resulting cocktail on crops. "It now seems that when you roll these three things together, it has very negative consequences on the bees," Mussen told me.  

He explained that originally, adjuvants were used to help spread pesticides more evenly. Sprayed on their own, pesticides tend to form into discrete droplets on a plant's leaves that might not come into contact with insects or mold spores. Mixed with adjuvant, pesticides coat leaves evenly, making them more effective.

In recent years, the industry has come out with what Mussen calls "super-duper" adjuvants, that not only coat leaves but also penetrate them—which is desirable for growers because it prevents expensive agrichemicals from being washed away by rain or degraded by sun.

For bees, though, that development might be bad news. Mussen says it's possible that the bees' own skin tissues had been blocking the pesticides—until the new-and-improved adjuvants gave them a pathway inside. Also, he added, the chemicals "have some pretty potent material in them that we believe could be toxic to honeybees."

Mussen pointed me to a 2012 paper, published in the peer-reviewed PLOS ONE by Penn State University researchers, which found that, when consumed at low doses, new-wave adjuvants inhibit bees' ability to learn how to forage, compromising the long-term health of the hive. (Penn State's press release on the paper has more explanation; and here's more still from the research team itself.)

And while pesticides have to go through a registration process with the Environmental Protection Agency before they can be unleashed upon the world, adjuvants are considered "inert" ingredients and aren't subjected to EPA review, Mussen said. And while the EPA process for assessing the impact of pesticides on honeybees is deeply flawed, as I have shown before, at least there's a process in place. For adjuvants, there's no bee testing at all, he added. And by adding them to pesticide mixes and spraying them on almond trees, farmers aren't breaking any California or USDA rules.

It all adds up to yet another pathway linking pesticide cocktails and our beleaguered honeybee population. Pesticides and fungicides widely used in Midwestern corn and soybean fields have been shown to damage bee health—and these operations are also increasingly using adjuvants in their pesticide mixes, too. The above-mentioned PLOS ONE paper concluded that these unregulated chemicals may "contribute to the ongoing global decline in honey bee health." But corn and soybean farmers don't need bees to achieve their harvests. That bee-reliant almond growers would engage in practices that might severely harm bees…well, that's just nuts.

Trouble in the Almond Orchards

Bug Squad - Happenings in the Insect World   By Kathy Keatley Garvey      April 23, 2014

Beekeepers and almond growers are concerned--and rightfully so--about the some 80,000 bee colonies that died this year in the San Joaquin Valley almond orchards. In monetary terms, that's a loss of about $180,000. But the loss isn't just financial. It could have long-term effects.

Beekeepers believe that pesticides killed their bees after the almond pollination season ended but just before they could move their bees to another site. This is a serious blow to both industries. Growers need the bees to pollinate their almonds. Now some beekeepers are vowing this is it; they'll never to return for another almond pollination season.

Extension apiculturist Eric Mussen of the UC Davis Department of Entomology and Nematology talks about the issue in his latest edition of from the uc apiaries, published today on hiswebsite.

"When should the colonies be allowed to leave the orchards?" he asks. "When pollination no longer is happening. That does not mean that the bees should remain in place until the last petal falls from the last blossom."

"Why might beekeepers desire to move their hives out of the orchards 'early?' Once the almonds no longer provide nectar and pollen for the bees, the bees find replacement sources of food. Unfortunately, those sources may be contaminated with pesticides that almond growers would never use when the bees are present. Some common pests that surge right near the end of almond bloom include Egyptian alfalfa weevil larvae and aphids in alfalfa, and grape cutworms in vineyards. Delayed dormant sprays sometimes are being applied in other deciduous fruit orchards, even when the trees are in bloom. Often blooming weeds in the crops are attracting honey bees. If the year is really dry, the bees may be attracted to sugary secretions of aphids and other sucking bugs."

Mussen says it's "not difficult to see that accidental bee poisonings often happen. Despite our California regulations requiring beekeepers to be notified of applications of bee-toxic chemicals within a mile of the apiaries, bees fly up to four miles from their hives to find food and water. That is an area of 50 square miles in which they may find clean or contaminated food sources. Thus, growers whose fields are 'nowhere near' any known apiary locations may accidentally kill many bees with chemical applications."

"It seems," Mussen says, "that a combination of exposures of colonies to truly bee-toxic insecticides, followed by delayed effects of exposure to fungicide/IGR mixes during bloom, really set the bees way behind. The problem proved so severe that a number of beekeepers stated that they were never returning to California for almond pollination. That is not a good thing, since we really don't have too many colonies coming to almonds as it is."

In his newsletter, Mussen goes into depth about when and how bees pollinate the almonds and what could be causing the problem and how it can be resolved.

His take-home message? "Our honey bees cannot continue to be exposed to as many toxic agricultural products as they are, or we will not have enough bees to fill the pollination demand for our nuts, fruits, vegetable, forage and seed crops."

That's serious business.

Bee Supply and Demand Should Be Balanced for Almond Bloom

The following is brought to us by the American Bee Journal.  
Western Farm Press    By Greg Northcutt   2/19/14 

 

With many almond orchards reaching full bloom by the third week of February, California growers appear to have all the bees they’ll need to pollinate their trees this season.

That contrasts with last year when growers barely had enough bees due to adverse weather and a poor honey crop in 2012 in California and many other areas of the country that supply the bees.

“I doubt if there’s any shortage,” says Gordon Wardell, bee biologist for Paramount Farming Company. “Most of the beekeeper’s I’ve talked with are sitting long this season.”

Bee industry veteran Joe Traynor, whose company, Scientific Ag Co., Bakersfield, Calif., provides pollination services, offers a similar assessment. “It looks like the numbers will come out even between what the growers want and what the beekeepers can provide,” he says.

One reason is that beekeepers responded to the small supply of bees for last year’s almond crop by boosting their colony counts in 2013.

To hedge against winter losses, beekeepers typically increase bee numbers by splitting about 10 percent of their colonies into two separate ones in spring and summer.  In 2013, many beekeepers boosted their number of splits to cover 30 percent to 40 percent of their total bee numbers. This provided a good supply of replacements and extra colonies across the country to meet the increased demand.

“Imagine a cattle rancher increasing a herd by 30 percent to 40 percent a year just to cover potential losses,” Wardell comments.

As it turned out, this past winter in many areas wasn’t as hard on the bees as usual and new mite control measures resulted in lower than expected winter losses. The exception occurred in some areas of the upper Midwest where losses were heavy. Otherwise, around the country bee numbers were generally good. With more bees to begin with and lower winter losses, beekeepers ended up with a good supply of bees for this year’s almond pollination, he notes.

The number and condition of bees available for this year’s almond bloom varied among different regions of the country. For example, cooler, wetter weather in Wisconsin, Minnesota and the Dakotas last summer, reduced the number and strength of the hives there.

Meanwhile, lower winter mortality rates resulted in more bees in the South, including Florida and Texas. On top of that, increased spraying of orange, lemon and grapefruit groves there to control Asian citrus psyllid, which spreads Huanglongbing disease, prompted beekeepers to find a less-threatening environment in which to place their hives.

“California was an obvious choice for them at this time of year,” Wardell says.

The size and quality of the colonies this season is reported to be roughly the same as last year. “I doubt if you could tell the difference,” he says. “The hives may be half a frame smaller, if at all.”

Growers like to see eight frames of bees in their hives. Many will pay a bonus for more.

Most almond growers sign contracts with beekeepers in July and August to deliver bees for the following season. Concerns last summer about a possible shortage of bees from the upper Midwest for this year’s bloom pushed rental prices up about $10 to $20 a hive this season, Wardell reports. One estimate puts the average prices of colonies this year in the $160 to $170 range.

Pollen jackpot

Once almond flowers open and begin shedding pollen, bees can pollinate a tree in full bloom in about four or five days. However, the bloom in orchards tends to stretch out over several weeks as different cultivars come into bloom and each tree spreads out its blooming period, large in response to such environmental conditions as heat, humidity and soil moisture.

Many almond orchards received about twice the normal amount of chilling hours this winter, Traynor notes. “Usually, that indicates an early, flash bloom,” he says. “But, this year’s bloom seems to be occurring at the normal time. Based on field reports, I look for more of a strung out bloom.”

Almond flowers provide a rich source of pollen and nectar for the bees. For them, the annual California almond bloom, which has been called the world’s largest pollination event, is the jackpot of all pollen-nectar jackpots.

During bloom, growers commonly stock their almond orchards with two colonies per acre. In all, pollinating their 810,000 acres of bearing trees requires about 1.6 million colonies — two-thirds of all the commercial colonies now available in the United States.

With another 60,000 or so acres of trees expected to come into production in the next few years, the demand for bees will only increase. Meanwhile, the number of bee colonies has been static, if not declining, raising the possibility of a future shortage of bees for California’s almond bloom.

More than 60,000 acres of almonds are expected to come into production in the next few years. That doesn’t necessarily mean a corresponding increase in the demand for bees, Traynor notes. “These new plantings could well be offset by 60,000 acres or more being pulled out after the 2014 harvest due to lack of water and/or age of trees,” he explains. “Orchard productivity declines after 15 years and some 20-year old orchards with declining production are still being farmed due to current robust almond prices.”

About 200,000 to 400,000 colonies needed for the almond bloom come from California apiaries. The rest are trucked in by beekeepers from various parts of the country, many of them in the Plains and Upper Midwest. In the past few years, beekeepers in some of those areas, such as Nebraska and the Dakotas, have been losing prime forage land for their colonies. Attracted by strong prices, farmers have been replacing alfalfa and clover fields with corn and soybeans, both of which our poor food sources for bees. This has resulted in weaker colonies.

These changing cropping practices have also reduced desirable habitat for pheasants. “Bees and pheasants share a common problem,” Traynor says. “A coalition of beekeepers and pheasant hunters could be helpful in finding a solution.”

In the absence of natural forage, beekeepers are forced to feed expensive, but less healthful, sugar syrup and protein supplements. Typically, this intensive, supplemental feeding starts when crops and other vegetation begin to dry down in later summer and continues through the winter. That’s when bee colonies naturally reduce their numbers from say, eight frames per hive, to just three or four to survive.

However, last year, drought prompted many of California’s beekeepers to start feeding their colonies right after bloom, continuing through December.

“To produce a strong eight-frame colony in the winter, when almond trees start blooming, beekeepers have to feed quite a bit of supplement,” Traynor says. “It’s not easy to do and it’s expensive.”

“You have to take your hat off to the beekeepers,” Wardell adds. “As the demand for bees has increased, they’ve stepped up to supplying the bees.  Beekeepers face a wide range of challenges – from dealing with Varroa mites, nosema fungus and Colony Collapse Disorder to moving their bees across the country. They’re doing a marvelous job of producing healthy colonies to support California’s agriculture.”

The Almonds are Blooming! The Almonds are Blooming!

Bug Squad - Happenings in the Insect World   By Kathy Keatley Garvey    2/19/14

Everyone has a favorite almond tree, right?

Mine--well, it's not exactly mine!--is on the grounds of the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, University of California, Davis.

It's spectacular in bloom. You can hear the buzz of honey bees, the tweeting of birds, and occasionally, an airplane droning over the field or a hog squealing from the nearby UC Davis hog farm.

But the sounds of the bees empower us and assure us that spring is coming. This particular almond tree, with its low hanging branches,  is an addiction and a good place to get "a fix."

Meanwhile, 1.6 million honey bee colonies, trucked in from all over the United States, are pollinating California's 810,000 acres of almonds. Each acre requires two bee hives. 

California growers produced 1.88 billion pounds of almonds for the 2012-13 crop year, according to Christine Souza's Dec. 11, 2013 article in Ag Alert.   The 2013-14 crop is estimated at 1.85 billion pounds.

A little less than last year but that's a lot of almonds! And a lot of buzz in the almonds...
