The Center for Biological Diversity and the Audubon Society of Portland sued the U.S. Fish & Wildlife Service (FWS) to protect streaked horned larks as endangered. The lawsuit challenges FWS’ April 2022 decision to list streaked horned larks as threatened instead of endangered. The complaint argues that the lesser protections would exempt agricultural activities, a leading threat to the species, from Endangered Species Act safeguards. Plaintiffs are seeking declaratory judgment and remand of the April 2022 listing decision for a new final listing determination. The case was filed in the U.S. District Court for the District of Oregon, Portland Division.
