August 5, 2015 — Four conservation groups filed a formal notice of intent to sue the U.S. Fish and Wildlife Service today seeking to strengthen protections for the streaked horned lark, which has lost 98 percent its grassland habitat. The lawsuit will challenge an October 2013 decision by the agency to protect the lark as “threatened” rather than the more protective “endangered” status and to exempt all agriculture, chemical spraying, and airport activities from the prohibitions of the Endangered Species Act regardless of whether they harm the lark.
