Excerpt from Management of Subalpine Forests, Building on 50 Years of Research: Proceedings of a Technical Conference, Silver Creek, Colorado, July 6-9, 1987 Although Indians, probably Utes and possibly Arapahos, undoubtedly entered the St. Louis Creek drainage from time to time before the arrival of the white man, they left little or no visible evidence of their presence. With the settlement of the West, however, miners and trappers came into the valley in the late 18005. Numerous ruins of mine shafts and cabins attest to their presence. The earliest recorded mining claims near St. Louis Pass date from the early 19005. Most of the miners were looking for gold, but found lead, zinc, and silver. In addition to those claims near St. Louis Pass, early miners were active in the Iron and Mine Creek drainages (fig. Mining continued on a limited basis in upper Mine Creek through the 19505. How ever, the volume of ore extracted was never high enough to warrant extensive operations. The Fraser Experimental Forest was withdrawn from mineral entry in the early 19505, and today there is no mining activity on the Forest. On May 12, 1905, that part of St. Louis Creek drainage that lies north of Sections 32, 33, 34, and 35, tis, r76w, gpm was set aside as part of the Leadville Forest Reserve. The Leadville Reserve included southern Grand County from Kremmling, Hot Sulpher Springs, Fraser, and east to the Continental Divide. On July 1, 1908, it became part of the Arapaho National Forest when that Forest was established. The land north of that line was in private ownership at the beginning of this century.

Historically the management of public lands from a multiple use perspective has led to a system that emphasizes those habitat components or faunal elements that primarily resulted in some sort of definable economic value. While this often benefitted other species that were not even considered in the original prescriptions, it also negatively impacted others. We no longer can afford to take this simplistic view of ecosystem management. We need to use a more holistic approach where ecological landscapes are considered as units, and land management practices incorporate all elements into an integrated policy. This includes examining the impacts of proposed land uses on amphibian, reptile, and small mammal populations.

Whitebark pine is a dominant feature of western high-mountain regions, offering an important source of food and high-quality habitat for species ranging from Clark's nutcracker to the grizzly bear. But in the northwestern United States and southwestern Canada, much of the whitebark pine is disappearing. Why is a high-mountain species found in places rarely disturbed by humans in trouble? And what can be done about it.Whitebark Pine Communities addresses those questions, explaining how a combination of altered fire regimes and fungal infestation is leading to a rapid decline of this once abundant -- and ecologically vital -- species. Leading experts in the field explain what is known about whitebark pine communities and their ecological value, examine its precarious situation, and present the state of knowledge concerning restoration alternatives. The book. presents an overview of the ecology and status of whitebark pine communities offers a basic understanding of whitebark pine taxonomy, distribution, and ecology, including environmental tolerances, community disturbance processes, regeneration processes, species interactions, and genetic population structure identifies the threats to whitebark pine communities explains the need for management intervention surveys the extent of impact and losses to dateMore importantly, the book clearly shows that the knowledge and management tools are available to restore whitebark pine communities both locally and on a significant scale regionally, and it provides specific information about what actions can and must be taken.Whitebark Pine Communities offers a detailed portrait of the ecology of whitebark pine communities and the current threats to them. It brings together leading experts to provide in-depth information on research needs, management approaches, and restoration activities, and will be essential reading for ecologists, land managers, and anyone concerned with the health of forest ecosystems in the western United States.
