Protecting the BEES The Obama administration, rushing to secure its environmental legacy, has increased protection for a humble bumblebee. The rusty-patched bumblebee, once common across the continental United States, has been designated an endangered species by the Fish and Wildlife Service: the country’s first bumblebee, and the first bee from the lower 48 states, to be added to the register. Seven bees were previously listed as endangered, but they are found only in Hawaii. Since the late 1990s, the population of the rusty-patched bumblebee has declined by nearly 90 percent, a result of a combination of factors, including exposure to pesticides, climate change, habitat loss and disease, federal wildlife officials said. The species, once found in 28 states, the District of Columbia and two Canadian provinces, is found today only in small pockets of its once-sprawling habitat. The designation will accelerate efforts to protect the bees’ habitat and to reduce the use of pesticides that are killing them.
