ABSTRACT EXCERPT: We tested the use of high-resolution infrared (IR) camera technology and distance sampling analyses to estimate abundance of feral horses (Equus caballus) during 2015–2016 in the McCullough Peaks Herd Management Area, Wyoming, USA. Infrared technology is becoming more common in ungulate population monitoring….We conducted 2 aerial surveys in a sagebrush ecosystem with a demographically closed horse population. True abundance was known to within 4 animals as a result of intensive,ground-based monitoring of each animal, all of which are uniquely identiﬁable. ….Our analyses yielded results that were within 10% of true abundance, but the coefﬁcient of variation (CV) was large (36–58%) assuming a small sampling fraction…We found the combination of IR surveys and distance sampling analysis to be a useful method to estimate feral horse abundance in sagebrush vegetation type, which had limited cover to obscure horses…

Abstract Excerpt: 'Because little is known about the status of CSTG in Wyoming, we sought to model the relative probability of lek site occurrence within the known distribution of CSTG in the state to identify areas that contained previously undocumented lek sites. [..] In areas identified by the RSF, we searched for leks by conducting ground surveys and surveys from a fixed-wing airplane using aerial infrared (AIR) technology. '
