SummaryACE Act provides opportunity to fund wildlife conflict reduction nationwide Across the United States, iconic wildlife like grizzly bears, wolves, and other endangered and threatened species share lands and waters with humans and incur costs to livestock production and other resource-based livelihoods. Grizzly bears and wolves depredate and stress livestock. Golden eagles prey on lambs. Seals compete with fisherman for valued catch.  Given the expanding range and population of such species, including reintroduction efforts of large carnivores throughout their historic range, the need for additional wildlife-livestock conflict prevention work and depredation compensation is rapidly increasing. At the same time, federal funding to support non-lethal conflict prevention work and supplement state-level livestock depredation compensation funds has remained relatively flat, and nowhere near enough to meet the demand. This is evident in the Wolf Livestock Loss Demonstration Project Grant Program (Tester Funds) administered by the U.S. Fish and Wildlife Service (FWS) authorized in 2009, which continues to receive only $1 million annually in funding. This program provides grants to state agencies to administer non-lethal conflict prevention techniques, and supplement existing state programs that compensate producers for livestock loss, but is often nearly fully expended in only a handful of western states, while being species specific to wolves. Recognizing that this annual appropriation falls well short of the need, Congress authorized the Grant Program in the America's Conservation Enhancement Act of 2020. The Grant Program for Losses of Livestock Due to Depredation by Federally Protected Species (Grant Program) within the American Conservation Enhancements (ACE) act, if fully funded, would provide $15 million annually through Fiscal Year 2025 for state-implemented compensation and conflict prevention programs.
