Susan Cobey is internationally known for her expertise in honey bee breeding and instrumental insemination. She teaches classes that draw students from throughout the world. A bee breeder and geneticist for more than 30 years, she developed and maintains the world-renowned New World Carniolan stock.
“Researchers are still collecting more samples from collapsing colonies and trying very hard to process those and previous samples to see what may be causing the problem,” said UC Davis Extension apiculturist Eric Mussen, who believes that CCD is not caused by one single factor, but multiple factors, including malnutrition, pesticides, diseases, parasites and stress.
“Nearly every state in the U.S. has some to many beekeepers who are having difficulty with losses that appear to be CCD,” said Mussen, Extension apiculturist at UC Davis since 1976 and a former state and national beekeeper of the year. “Many countries are encountering similar bee losses. Since we don't know what is causing ours, or theirs, we cannot say that the cause(s) is the same, but it is likely.”
In CCD, nearly all adult worker bees unexpectedly fly away from the hive, abandoning the stored honey, pollen, larvae and pupae. Usually they leave in less than a week, and only the queen and a few young workers remain, Mussen said.
CCD is not a new occurrence, Mussen said. “Similar phenomena have been observed since 1869. It persisted in 1963, 1964 and 1965 and was called Spring Dwindling, Fall Collapse and Autumn Collapse. Then in 1975, it was called Disappearing Disease. But the disease wasn’t disappearing—the bees were.”
Can we surmise what the future holds for bees? “No, we cannot,” Mussen said. “We hope that this episode will just be one in a number that have occurred, and resolved themselves, in the past.”
At the House Agriculture Subcommittee on Horticulture and Organic Agriculture hearing on June 26 to review the status of pollinator health and CCD, subcommittee chair Cong. Dennis Cardoza of California’s 18th District, said that the “importance of bees and other pollinators cannot be underestimated. Nearly 130 different crops—totaling over $15 billion in annual farm gate value—depend on pollination to grow.”
Testimony revealed that the lack of pollinators could further increase food prices. Said Cardoza: “USDA desperately needs to better coordinate their research and response to this ongoing crisis, and more clearly define their needs so that Congress can adequately respond.”
“Should the CCD crisis continue unchecked, pollinated ingredients such as strawberries, cherries and almonds could become scarce or too expensive to obtain, forcing us to evaluate whether we can continue offering popular flavors that depend on pollinated ingredients because of higher production costs,” Pien said.
Those interested in making online donations to UC Davis to help save the honey bees can access the UC Davis Department of Entomology Web page. Or, checks may be made out to “UC Regents” and mailed to the UC Davis Department of Entomology, One Shields Ave., Davis, CA 95616.
Rain Gardens and Bioretention Basins To
Improve Water Quality and Save 30% More Rainwater
California's water supply is more fragile and seasonal than in most of the country because we are in "the West". Seasonal rains in our desert areas can be severe, and water retention for the rest of the year is dependent on snowpack, water tables and manmade lakes.
When rains come, we need to capture that fresh water for use by the flora and fauna in our communities. Capturing it also prevents runoff from roofs, streets, parking lots and lawns from washing pollutants into streams, rivers, lakes and eventually the ocean. Runoff pollutants can include fertilizers, pesticides, car waste such as oil and fluids, pet waste and its bacteria, eroded soil, road salt, grass clippings and litter. Rain gardens will not remove ALL these pollutants, but they do remove some of them as the water seeps into the ground, which serves as a natural filter.
A beautiful, useful way to capture rainwater runoff is with a
"raingarden" that is well designed, well placed and serves as a cache
basin that filters and helps the water find its way to the roots of
plants...and our watertable.

Congratulations to Melissa Mansfield, the new host of "Keep It Green"!
I met Melissa when she was working on a Los Angeles green living blog, and am delighted to see that she is moving into her dream of sharing green and sustainable strategies with the community. Go, girl!
FIRST EPISODE: "So, it was exciting that my first interview as Keep It Green's new host was with Lou Cafiero of NOAA's National Marine Sanctuaries. Our oceans are home to a vast array of diverse species, all playing vital roles in our environment. Marine sanctuaries play a large part in protecting that abundance of life.
And there's a lot of work to do. Until I talked with Lou, I had no idea that whales face some very unique dangers - one of which is getting hit by huge shipping vessels. These ships move extremely fast, and if a whale is busy feeding or otherwise distracted, it can get hit and seriously injured or killed."
