Today conservation and food safety groups filed a petition with the California Fish and Game Commission to list four species of native bumble bees—western bumble bee, Franklin’s bumble bee, Crotch’s bumble bee and the Suckley cuckoo bumble bee—as Endangered under California’s Endangered Species Act.

Bumble bees are among our most recognizable and well-loved insects. Usually yellow, black and fuzzy, they are found throughout the state. Recent studies have revealed that several bumble bee species in California are imperiled and in need of immediate conservation attention.

Along with other types of bees, bumble bees are essential to the reproduction of many of California’s specialty crops, including tomatoes, peppers, melon, squash, cotton and almonds, as well as to native ecosystems—from the flower fields of the Carrizo Plain to the montane meadows of the Sierra Nevada. Conserving a diversity of native pollinators within the state is paramount to maintaining the state’s natural heritage, as recognized in California’s new Biodiversity Initiative, which calls for fallowed agricultural land to be transformed into habitat for bees, creating a “pollinator highway” across the state. They are also essential for food production.

“Native pollinators, including bumble bees, provide ecosystem services estimated at more than nine billion dollars annually in the U.S.,” said Sarina Jepsen, director of the Xerces Society’s endangered species program and petition coauthor. “By acting on this petition, California has an opportunity to demonstrate how an individual state can lead the nation in protecting a diverse suite of pollinators, benefiting both agriculture and natural areas.”

Together, the historic ranges of the western bumble bee, Franklin’s bumble bee, Crotch’s bumble bee and the Suckley cuckoo bumble bee cover much of the state, but currently populations persist in very few areas. The western bumble bee, for example, was one of the most common bumble bees within its range prior to the late-1990s, but in California is now found only in a few sites in the Sierra Nevada and the northern coast. These four species of bumble bee are primarily threatened by habitat loss, diseases and pesticides.

“California’s native bees are essential to keep our state blooming,” stated Kim Delfino, California Program Director for Defenders of Wildlife. “Current regulations have proven insufficient to reverse the sharp decline in populations and protection under our state endangered species act is the last line of defense if we hope to keep these four bee species from going extinct.”

Protecting these species will help to maintain the healthy ecosystems that make California such a remarkable and productive state. Over 80% of all terrestrial plant species require an animal pollinator (usually an insect) to reproduce. About one-third of food production depends on pollinators, and 75% of all fruits and vegetables produce higher yields when visited by pollinators. California accounts for more than 13% of the nation’s total agricultural value, and protecting these four bee pollinators is an important component of protecting California’s agricultural legacy.

”One out of every three bites of food is dependent on pollinators such as bees,” said Rebecca Spector, West Coast Director at Center for Food Safety. “The diversity and strength of bee populations is critical to maintaining a healthy and robust food supply in California and beyond.”

Listing these bumble bees under the California Endangered Species Act will protect them from ‘take’, including activities that could cause them to go extinct, and will allow for additional conservation measures to be implemented. Efforts are already underway to restore habitat for bees on farms and in cities throughout California. An increased investment in pollinator habitat, along with protection from insecticides and pathogens, will be required to prevent extinction of these bumble bees.

Western Caucus Members Push Anti-Endangered Species Act Bills, Again

It’s looking like déjà vu all over again as the Congressional Western Caucus has begun to introduce another package of anti-wildlife, anti-public lands, anti-Endangered Species Act (ESA) bills. The new package of stand-alone bills is – so far – nearly identical to draft legislation the caucus released this past fall. And, like the previous package, the bills would eliminate key protections for wildlife that have been in place for more than 45 years.
