The US Geological Survey is offering a funding opportunity to a CESU partner for research on wild horse population demography and ecology throughout the Western USA. This research will be comprised of a combination of field-based data collection and research, and data analyses through modelling techniques. The National Academies of Science (NAS) conducted a science review of the Bureau of Land Management (BLM) wild horse and burro program in 2013. An outcome of this NAS review was a number of recommendations for new research, identification of data gaps, and knowledge needs. The aim is to fill some of those data needs with collaborative research conducted jointly by USGS and CESU partner.
