The Wildlife Society supports the Bureau of Land Management’s (BLM’s) National Wild Horse and Burro Program and its mission to ensure that healthy herds thrive on healthy rangelands.1 However, with on-range populations continuing to dramatically exceed ecologically sustainable levels, The Wildlife Society grows increasingly concerned about the Administration’s lack of progress in implementing management options targeted at reducing population size. The continued overpopulation of federally managed horses and burros on public lands threatens the ecological integrity of our rangelands while unduly impacting the ability of wildlife professionals to effectively manage and promote healthy rangelands and native species for future generations.
