The Geological Survey is offering a funding opportunity for a Cooperative Ecosystem Studies Unit (CESU) partner to conduct research on wild horse population demography and ecology throughout the Western USA. This research will involve field-based data collection, research, and data analyses through modeling techniques. The aim is to address the recommendations for new research, identification of data gaps, and knowledge needs identified by the National Academies of Science (NAS) in their review of the Bureau of Land Management (BLM) wild horse and burro program in 2013. The funding opportunity is a Cooperative Agreement and there is no cost sharing or matching requirement. The closing date for electronically submitted applications is May 22, 2024, at 5:00 p.m. ET.
