For the first time in U.S. history, bees will receive protection under the Endangered Species Act.

Seven yellow-faced bee species, Hawaii's only native bees, are now considered endangered after years of extensive research, according to The Associated Press.

The yellow-faced bees pollinate plant species indigenous to the Hawaiian islands, some of which are also endangered. In addition, these bees favor heavy shrubs and trees, supporting the health of forest regions, which provides a habitat for other animals.

The bees face threats from "feral pigs, invasive ants, loss of native habitat due to invasive plants, fire, as well as development, especially in some for the coastal areas," Sarina Jepson, director of the Xerces Society, told The Associated Press.

The protection goes into effect Oct. 31, according to CNN.
