Lorenci(o Canvon Mint - Wildlife Technical Report <br />• <br />Perhaps the best available estimate of population size is provide by the pellet-count analyses <br />(Table W-3). Based on these data, an average of approximately 8 to 229 elk were distributed <br />across the permit area during 1996. This estimate is equivalent to a density of < 1 to 8 elk mile`. <br />However, the small sample size associated with this estimate tend to make the estimate somewhat <br />questionable. The CDOW data indicate that the elk herd has been increasing since 1990 (CDOW, <br />1995). <br />Mule Deer <br />Mule deer occur throughout the permit area. The CDOW has identified the permit area as mule <br />deer overall range, mule deer winter range, and the western portion of the permit area as a winter <br />concentration area (Figure W-2). The definition of overall and winter ranges is the same as <br />described for elk. Winter concentration areas are defined as that part of the winter range where <br />densities are at least 200 percent greater than the surrounding winter range density during the same <br />period used to define winter range in the average five winters out of ten (CDOW, 1996b). <br />Mule deer within the permit area are pazt of the Trinidad herd and aze contained within DAU 32. <br />This DAU is approximately 1,995 square miles of which 88 percent is private (Davies, 1996). <br />However, the permit azea occupies about one percent of DAU 32. Like elk, the permit area also <br />• is contained within Hunt Unit 851. The CDOW estimates 11,843 deer make up DAU 32 with a <br />buck:dce ratio of 35:100 (CDOW, 1995). The rifle hunter success for Hunt Unit 851 ranges from <br />43 to 58 percent (CDOW, 1996g). <br />The management objective for DAU 32 is to increase the population by 1999 to 12,964 with a <br />buck:doe ratio of 38:100. This represents an approximate two percent increase each year <br />(CDOW, 1995). In addition, harvest rates are anticipated to remain at between six and seven <br />percent of the herd until 1999 (CDOW, 1993b). <br />The 1996 surveys indicate deer were using virtually all the habitat types available in the permit <br />area. Roadside count surveys located deer in three types: oak/pinyon, coniferous forest, and <br />mountain shrub (Table W-4). Most of the deer observed during the roadside count surveys were <br />in the oak pinyon habitat (65 percent). Like elk, the limited sight distance within the coniferous <br />forest type probably reduced observation opportunities in this type. <br />The pellet-count transect data indicted that the coniferous forest received the greatest amount of <br />use during the late winter-early spring period (Table W-3). The pellet-count analysis also <br />indicates the mountain shrub type was used consistently throughout the late winter, spring, and <br />summer (Table W-3). Also, grassland pellet groups were lacking over the summer. However, <br />this may be due to the loss of the transects within the grassland habitat. The survey points were <br />lost due to range improvements and pellet groups had to be estimated in this area. Estimates were <br />made by measuring the distance from a known starting point to the approximate location of the <br />• next point. Once this point was located the pellet groups within the 0.01 acre area were counted. <br />WilAli&A75/December 9, 1996 12 <br />
