Tiny Saviors in Our Backyard
If you're interested in native bees, you'll want to read the newly published University of California research article, "Tiny Saviors in Our Backyard."
Native pollinator specialists Robbin Thorp and Neal Williams of the UC Davis Department of Entomology are featured in the article as is conservation biologist Claire Kremen of UC Berkeley.
Author Erik Vance describes Thorp, emeritus professor of entomology, as "the patriarch of a rag-tag group of scientists who have pioneered research on non-honey bees that just may hold a solution to the world’s pollination problems."
Williams' work with conservation biologist Claire Kremen of UC Berkeley involves monitoirng which native bees are effective on Yolo County farms.
It's great to see so much attention on native bees.
As Vance says, "Honey bees get most of the buzz, but some native bees are better at spreading pollen. They may hold the solution to world pollination problems that affect important crops."
Honey bees are often considered "native" bees but they are not. English explorers brought them to America beginning in the 1620s.
The Xerces Society of Invertebrate Conservation, based in Portland, Ore. (and celebrating 40 years of conservation this year), is rightfully pleased with the UC scientists' work.
“The work out at the UC is some of the best work in the country right now,” Mace Vaughan, who oversees national pollinator work for Xerces, told Vance. “They are actually demonstrating the benefits.”

Protecting the Pollinators
Writing for the Nature journal, Sharon Levy recently examined pollination studies that focus on the importance of pollinators and the plants they frequent.
Levy mentioned the work of conservation biologist Claire Kremen of UC Berkeley; Rachael Winfree, a pollination biologist at Rutgers University in New Brunswick, N.J.; and native pollinator specialist Neal Williams of UC Davis.
Williams led one of the studies that found that "most native bees are far less picky than was imagined," Levy wrote. The study showed that "bees collect pollen from both alien and native plants in proportion to a plant's abundance in the landscape," she related. "In highly disturbed habitats, bees make greater use of alien plants--not because the bees prefer them, but simply because introduced plants are far more common where people have transformed the landscape."
Last year Williams received a three-year federally funded research grant aimed at improving pollinator habitat plantings in nationwide agricultural settings. Williams said at the time:
“Recent declines in honey bee populations and the threat of losses in pollination service to economically important crops has raised awareness of the importance of restoring and conserving native bee diversity and abundance. We will be developing simplified assessment tools that will allow land stewards to evaluate the cost-effectiveness of future habitat restorations."
In 2000, the economic value of insect-pollinated crops in the United States was estimated at $18.9 billion.
Kremen, Winfree, Williams and Mace Vaughan, pollinator program director of the Xerces Society for Invertebrate Conservation, were among the specialists sharing their expertise at the 59th annual Entomological Society of America's meeting, held Nov. 13-16 in the Reno-Sparks Convention Center.
At one of the ESA seminars, Winfrey said that about 75 percent of the nation's crops require pollination, and that there are 20,000 species of native bees.
Kremen pointed out that "35 percent of the food we eat is pollinated by bees."
Vaughan, in emphazing the need to protect the pollinators, announced the Xerces Society's newest publication, Attracting Native Pollinators: Protecting North America's Bees and Butterflies.
To attract native pollinators, the Xerces Society says that we need to:
--Ensure pollination in our gardens, orchards or farms.
--Identify the flower-visiting insects of our region.
--Provide host plants and nesting sites for bees and butterflies.
--Create a landscape that is beautiful, diverse and pollinator friendly.
Good advice. We all have a role to fulfill in attracting and protecting the pollinators.

In the Arms of an Almond Tree
It was Feb. 27, 2008. As a visiting researcher with the Environmental Science, Policy and Management at UC Berkeley, she was working on almond pollination research with UC Berkeley conservation biologist Claire Kremen.
Klein had earlier (2003) received her Ph.D. in agroecology and zoology from the University of Göttingen, Germany.
Today Klein is a professor at the University of Lüneburg, Germany and continues to study conservation biology and ecological interactions.
And more good news--she's in the Yolo County area for approximately five weeks for continuing almond pollination research, and while here, will present a lecture on the UC Davis campus.
Klein will speak on "Can Wild Pollinators Contribute, Augment, and Complement Almond Pollination in California?" on Wednesday, Feb. 17 at a UC Davis Department of Entomology noonhour seminar.
The seminar, set for 12:10 to 1 p.m., in 122 Briggs Hall, Kleiber Drive, is scheduled to be Webcast. Folks can listen live here. Later her talk will be archived.
Klein will be hosted by her fellow researcher and colleague, pollination ecologist Neal Williams, an assistant professor in the UC Davis Department of Entomology.
On Feb. 17, however, Klein won't be up a tree, but at the lectern.

Great Pollinator Site
What a treasure!
Have you seen the Xerces Society's new online Pollinator Conservation Resource Center?
This is something that's long been needed. It's a wealth of information--that's why it's a treasure.
As Matthew Shepherd of the Xerces Society for Invertebrate Conservation says: "...the resource center gives access to all you need to complete a pollinator conservation project in any region of the United States. When you visit the resource center, select your region from the map to access plant lists, details of creating and managing nest sites, pesticide protection guides, and practical guidance on planning and implementing habitat projects on farmlands, gardens, golf courses, parks, and wildlands."
"We want the resource center to be the most comprehensive source of pollinator conservation information currently online and will update it as often as we can, adding new materials as they become available."
Shepherd says the resource center is "the result of a collaboration with Neal Williams of the University of California, Davis. In particular, we thank Katharina Ullmann, previously with the Xerces Society and now a member of Neal Williams' research group, for gathering many of the resources."
Among the others lending their expertise: native pollinator specialist Robbin Thorp, emeritus professor of entomology at UC Davis who maintains an office in the Harry H. Laidlaw Jr. Honey Bee Research Facility.
How easy is it to use this site?
Very easy.
Say, for example, you want to plant a bee friendly garden. All you do is click on a link and you'll know what to plant seasonally in your area and what each plant will attract. Then you can click on the various pollinators to see what they look like.
If this Web site were gold, it would be in Fort Knox.
