How You Can Help Count and Conserve Native Bees
Honeybees and their problems get the most attention, but scientists are using tactics learned from bird conservation to protect American bees.

In the last 20 years, the rusty patched bumblebee population declined by 87 percent because of habitat loss, use of pesticides and disease. This fuzzy bee, native to the continental United States, gets its name from the rusty patch on its back.
These bumblebees pollinate fruits and vegetables we eat, unlike the Gulf Coast solitary bee, which gathers pollen from only one plant — the Coastal Plain honeycomb head, a member of the aster family. You could say they’re specialists, whereas, rusty patched bumblebees and honeybees are generalists.
Honeybees — a European import to the Americas — and their colony collapse problems get a lot of attention, but native bees that have their own ecological role are facing similar and perhaps additional threats. The decline among native bees is a known problem, and there are a variety of efforts to save them; however, the full extent of the problem is not well understood.
“While regional studies have tracked the decline of native bees,” said S. Hollis Woodard, an entomologist at the University of California, Riverside, “there hasn’t been a coordinated nationwide effort to monitor these pollinators.”
Dr. Woodard and colleagues explained this problem in a paper published this month in the journal Biological Conservation, and proposed a new approach to monitoring native bees. But she and scientists at institutions across the United States are going beyond doing studies about the problem. They have also started an effort to collect better data on native bee populations, as well as efforts to conserve them, as part of the U.S. National Native Bee Monitoring Research Coordination Network. The project, supported by the U.S. Department of Agriculture, will train members of the public to look for and track wild bees.
“The data we collect will identify which conservation efforts are working,” Dr. Woodard said.
