Based on recent population growth due to active recovery efforts conducted by the New Mexico Department of Game and Fish (NMDGF), desert bighorn sheep (Ovis canadensis mexicana) have been removed from the state’s threatened and endangered species list. As a result of this delisting, desert bighorn sheep populations will be subjected to increased harvest in New Mexico. The NMDGF has identified the need to obtain estimates of lamb survival, recruitment and cause-specific mortality as part of ongoing efforts to manage for the continued growth of bighorn sheep populations in New Mexico. Our objectives are to: 1) estimate lamb survival and determine cause-specific mortality of neonatal desert bighorn sheep in the Peloncillo Mountains, New Mexico; and 2) continue ongoing monitoring efforts to determine causes of mortalities of adult bighorn sheep in the Peloncillo, Big Hatchet and Little Hatchet mountains.
