The first program was passed by the Commission in January 1985 in response to the increasing number of livestock being killed by lions in game management unit 30 (Fig.1). This Order instructed NMDGF to remove lions on ranches that had more than 4 verified depredations in a 4-year period. Each year,NMDGF could remove up to 14 lions from all ranches combined. In 1986 the Order was revised and the number of verified depredations required for lion removal was increased to 6 within a 3-year period;the maximum number of lions that could be removed yearly remained at 14. This program still operates according to those parameters. Fourteen lions were killed in 1999 (Table 5).

Currently,5 wild populations of Rocky Mountain bighorns totaling 600 sheep and 7 wild populations of desert bighorns totaling 200 sheep occupy New Mexico (W. C. Dunn, personal communication). Of 50 radiocollared bighorn mortalities between 1995 and early 2000, 37 (74%) were killed by cougars (Dunn 2000). In 1997, the Commission passed a regulation that instructed NMDGF to kill any lion that was known to have killed a bighorn sheep. Eight lions were killed that year but lion predation remained high. In 1999,the Commission passed another regulation allowing the removal of up to 34 lions per year,for 5 years,in 4 bighorn sheep ranges. This number is included in the harvest quota but allows for removal after the sporthunting season if the unit quota was not met during the season. Four houndsmen were contracted in 1999 to remove lions,but to date no lions have been removed under this program. RESEARCH # Preventative Permits Issued in Unit 30 # Males Killed in Unit 30 # Females Killed in Unit 30 # Unknown Sex Killed in Unit 30 Total # Lions Killed in Unit 30 The first study of mountain lions in New Mexico began in 1934 (Hibben 1937), documenting life history attributes in the northern and western portion of the state. From 1971 until 1980, NMDGF conducted research in southwestern New Mexico, investigating food habits and movement ecology and using radio telemetry (Donaldson 1975,Johnson 1982). The National Park Service funded a research study in southeastern New Mexico between 1982 and 1985,within Carlsbad Caverns and Guadalupe Mountains National Parks (Smith et al.1986). This study focused on population dynamics and provided basic ecological information of mountain lions in that region. From 1983-1985, NMDGF performed a study to determine the extent of illegal commercialization of mountain lions (Anonymous 1985). Most recently, NMDGF contracted Hornocker Wildlife Institute to conduct an intensive study of mountain lion ecology (Logan et al. 1996). This 10-year study examined population dynamics, social organization, interactions between mountain lions and mule deer and desert bighorn sheep, and mountain lion translocation as a management tool (much of this information was presented at the Fifth Mountain LionWorkshop).
