This EA was open for Public Comments from October 3 through November 1, 2016.  Based upon more recent census information, removing horses from this HMA has been postponed. However, the Rawlins Field Office still proposes to gather wild horses and fit up to 30 mares with GPS collar receivers to gather information on movements and habitat selection.
 
 
 
The objective is to collar up to 30 mares with Lotek GPS collars from five (5) spatially separate trap sites, located throughout the Adobe Town Herd Management Area (ATHMA). The use of GPS collars has been used to understand spatial movements across landscapes in Canada and Australia but to date has not replaced visual observation as the primary approach to measuring horse spatial patterns (Hampson et al. 2010; Girard et 22 al. 2013).  Each Lotek collar has an electronic drop-off device which enables any collar to be remotely dropped to ensure the well-being of the subject horse.  Several mule deer and pronghorn collaring studies have successfully been conducted in large portions of the ATHMA as well.  As another ungulate grazer competing for resources with mule deer and pronghorn, collar data from wild horses will enable much more accurate decision making capacity and reveal age old questions regarding questions of inter and intraspecific competition.
