"Almonds are one of the first crops of the season that need bee pollination," tweeted the Almond Board of California yesterday.
Valentine's Day traditionally marks the beginning of almond pollination season, but it's an early spring. The almonds are blooming and the bees are buzzing.
So, first the tweets, then the buzzes.
CNN Money, New York, came out Feb. 7 with a news story headlined "Honeybee Die-Off Shouldn't Sting." The Almond Board linked to it in its tweet.
The piece, written by Steve Hargreaves, explored the "good news and bad news on the honeybee beat."
Hargreaves said that colony collapse disorder (CCD) continues to claim about 30 percent of the nation's bees every winter. That's the bad news. The good news, he said, is that "beekeepers have been able to rejuvenate their hives each year so that by summer, the population is back to previous levels."
And "another bit of good news," Hargreaves pointed out, is that although agricultural yields are rising and "rejuvenating beehives is costly," the higher costs aren't being transferred in the supermarket.
Hargreaves quoted UC Davis agricultural economist Daniel Sumner as saying "It shouldn't be a significant item on the radar screen of consumers. It's not that big of a deal."
So, there you have it. Bees are in trouble. Almond production is up (about 750,000 acres in California and each acre requires two hives for pollination). And, demand for almonds is up. California now produces 80 percent of the world's almonds.
Meanwhile, honey bee guru and Extension apiculturist Eric Mussen of the UC Davis Department of Entomology, is repeatedly asked "How are the bees doing?" He writes a bi-monthly from the UC Apiaries newsletter and the periodic Bee Briefs, both posted on the Department of Entomology website.
Mussen attributes CCD (a mysterious malady characterized by adult bees abandoning the hive) to a combination of factors, including parasites, pesticides, pests, diseases, malnutrition and stress.
It continues to amaze us, however, what some folks think is causing CCD. They're looking for a silver bullet. There is none.
The arguments can get ugly. As debates continue to rage in the CNN Money commentary section, one reader, obviously exasperated, posted "...the writers in this place don't know anything about the realms of science, economics or ecology. And 90 percent of the posters aren't very bright, either."
Meanwhile, the bees are busy pollinating almonds.

It's not too early to start thinking about NPW.
NPW? National Pollinator Week.
They are a key to our global sustainability and food supply. Eighty-percent of the world's crops depend on pollination. Honey bees pollinate about one-third of the food we eat.
Worldwide, we have about 20,000 species of bees, according to native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis. And California alone, he says, has more than 1600 species. Bees include sweat bees, digger bees, leafcutting bees, bumble bees, and scores of others.
Want to know what to plant in your garden to attract bees and other pollinators? Good sites to read are UC Berkeley's Urban Bee Gardens Web site and the Xerces Society Web site.
Meanwhile, almond blossoms are in full bloom in California. At the Harry H. Laidlaw Jr. Honey Bee Research Facility at UC Davis, an almond tree near the apiary is a burst of blossoms and a flash of aromatic fury.
Walk by the tree and you'll see pollen-packing honey bees buzzing around like there's no tomorrow.
We must ensure there will be a tomorrow.

It's Presidents' Day today, a holiday for most of us but not for the honey bees.
The bees are buzzing in and around the almond blossoms, collecting nectar and pollen for their hives. Nectar provides the carbohydrates for the hive, and pollen provides the proteins.
Someone told me yesterday that she thought that the drones (males) gather the nectar and pollen. Not so. (Shades of the inaccurate information released in Jerry Seinfeld's "The Bee Movie" and the equally inaccurate term, "pollen jocks.") No, the only function of the drones is reproduction. When the virgin queen bee heads out on her maiden flight, she'll mate with 12 to 25 drones or so in the drone congregation area. Then the drones die. Happy, probably. If they don't mate, they'll die within a month. Sad, probably.
The queen bee, in peak season, will lay about 2000 eggs a day. The worker bees--all sterile female workers--serve as the nurse maids, nannies, royal attendants, builders, architects, foragers, dancers, honey tenders, pollen packers, propolis or "glue" specialists, air conditioning and heating technicians, guards, and undertakers.
It's a matriarchal society.
So when you see the bees buzzing around the almond blossoms, they're girls. Busy girls. Golden girls. They not only buzz, they rock.
They're the ones that pollinate one-third of the food we eat, including California's 700,000 acres of almonds.
You go, girls!

Plant it and they will come.
The Häagen-Dazs Honey Bee Haven, planted last fall, is already attracting a few honey bees.
The half-acre bee friendly garden, located next to the Harry H. Laidlaw Jr. Honey Bee Research Facility on Bee Biology Road, University of California, Davis, includes vegetables, fruit trees and nut trees (almonds).
Today a honey bee sipped water from the folds of a cabbage leaf as another honey bee landed on a visitor. Bee breeder-geneticist Susan Cobey, manager of the Laidlaw facility, gently plucked her off.
The almond trees at the haven are just about ready to burst into bloom.
Make way for the bees!
Plans are under way for a public opening at the haven and the nearby Campus Buzzway, which is planted with coreopsis, golden poppies and perennial lupine. The event is tentatively scheduled for the fall of 2010. More details will be announced soon.
The two gardens will provide bees with a year-around food source and an educational opportunity for visitors, who can learn about bees and glean what to plant in their own yards.
Make way for the bees!

What are insect pollinators worth to the global economy?
Well, it's a lot less than the Wall Street bailout...er...rescue plan.
Recent research published in the journal Ecological Economics reveals just how important insect pollinators are.
A Eureka Alert press release issued by the Helmholtz Association of German Research Centres says that a team of French and German scientists found that the "worldwide economic value of the pollination service provided by insect pollinators, bees mainly, was $153 billion in 2005 for the main crops that feed the world."
That amounts to 9.5 percent of the total value of the world agricultural food production.
The study says that fruit and vegetables account for about a third of that total. The bee shortage has already hurt growers and consumers worldwide. Pollinator disappearance "would translate into a consumer surplus loss estimated between $190 to $310 billion," the news release says.
A Sept. 26 article in Business Week noted that "California almond growers, who require 1.5 million bee colonies for pollination, are renting hives for $200 each, up from $35 two years ago. In China, where pesticide overuse has killed off pollinators in some fruit orchards, farm workers have resorted to dabbing pollen into blooms by hand."
California's growing almond acreage, which now exceeds 700,000, requires two hives per acre. Our state does not have enough bees to pollinate the almonds, so bees are trucked in all over.
Honey bee researchers think that stress may be one of the factors in the declining bee population. Other factors: malnutrition, diseases, pesticides, parasites and changing climates.
Colony collapse disorder, a phenomonon characterized by bees mysteriously abandoning their hives, is probably due to those multiple factors, according to UC Davis apiculturist Eric Mussen.
The declining bee population, the growing need for pollination, and the burgeoning U.S. financial crisis--those issues should concern us all.
