Two Democratic lawmakers on Thursday introduced legislation to protect wolves and grizzly bears even if the high-profile animals lose their Endangered Species Act protections.

With the Fish and Wildlife Service facing calls to delist grizzly bear and gray wolf populations, the companion bills introduced in both House and Senate would essentially provide a backstop.

Among other provisions, the measure would “prohibits the take, possession, purchase, sale, or transportation” of a bison, grizzly bear or wolf.

The ESA likewise prohibits the “take” of species listed as threatened or endangered. This covers everything from killing to harassing.
