Research for Management of America's Wild Horses and Burros

Science Center Objects

FORT scientists are leading collaborative research projects to provide the BLM with better tools for managing expanding wild horse and burro populations. We are assessing the carrying capacity of wild horse habitats, behavioral effects of spaying mares and gelding a proportion of a herd’s stallions, testing the efficacy of an intrauterine device for mares, and evaluating four fertility-control tools for burros. We are also developing aerial survey techniques for burros, testing the use of DNA extracted from dung to count wild horses, and evaluating effects of cattle versus horses on sage- grouse habitat. Collaborators include Colorado State University, BLM, Oklahoma State University, University of Massachusetts, and APHIS.
