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.

Buds 'n Blossoms
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.

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 "
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.
