The discus- <br />sion of species present in each vegetation type is based on the Colorado <br />latilong studies of mammals, birds, and reptiles and amphibians (Bisset <br />1978, Kingery b Graul 1918, Langlois 1978), my own observations, and <br />discussions with Colorado Division of Wildlife personnel and others <br />knowledgeable in the area. <br />Ponderosa Pine - Oak <br />In their report on the vegetation of the Allen Mine, Uniscale <br />Corp. (1980) described this type on a north-facing slope at 7,500 feet <br />just south of the area of mining activity. Pinon pine (Pinus edulisl, <br />• Rocky Mountain juniper Juniperus scopuZoramJ true mountainmahogany <br />~ J' (Cercocarpus montanusJ, Gambel oak (Quercus gambelli) with an under- <br />story of fortis and grasses provide food and cover that make this a <br />valuable habitat for wildlife. In their report, Uniscale (1980) also <br />described a ponderosa pine - Douglas-fir-oak type. pith the exception <br />of Douglas-fir, this type is similar to the ponderosa pine - oak and I <br />will not distinguish it here. <br />This type is capable of providing ideal cover and forage for elk, <br />deer and turkey. Most elk would be expected to migrate to the spruce-fir, <br />krummholz and alpine during late spring, summer and early fall. Deer to <br />a lesser extent, will migrate upward, but many may utilize this type <br />year-round. Turkeys will use it, and immediately adjacent areas, year-round <br />for feeding, nesting and roosting.
