Computer Terrain Mapping, Inc. 2005 map The Alpine Loop Ecological Resources data set shows the distribution of ecological resources (wildlife habitat) on lands along the Loop. This data set is one of the inputs used to determine the Conservation Resource Value. Several economic species (such as elk, mule deer, moose and bighorn sheep) along with threatened and endangered (T&E) species and species of special concern (such as bald eagle, lynx and Uncompahgre fritillary butterfly) occur in the Alpine Loop region. The computer analysis utilized the Colorado Division of Wildlife (CDOW) sponsored Natural Diversity Information System (NDIS) data, the Colorado Natural Heritage Program (CNHP) potential conservation areas, BLM (T&E) ACEC, BLM lynx habitat mapping and digitized white- tailed ptarmigan habitat. The Alpine Loop Spatial Analysis and Mapping Project inventoried natural and cultural resources and identified important areas where overlapping resources occur. The results from this project will provide an opportunity for area stakeholders - landowners, outdoor enthusiasts, surrounding communities, federal government agencies and local and national preservation groups - to come together to find solutions that maintain the Alpine Loop experience for future visitors and residents, while working within the framework of landowner objectives as well as local and federal government goals. The Alpine Loop Spatial Analysis and Mapping Project analyzed the Alpine Loop landscape, considering important natural and cultural resources along with the likelihood of development based upon building constraints. The Project aims to provide a planning tool for area stakeholders as they consider the variety of land management options and the future of this magnificent region. The next logical step will be to craft solutions that work within the framework of landowner desires, local and federal government land management goals, and available financial and technical resources to manage the area in a way that preserves the Alpine Loop experience for future generations. While the Alpine Loop lies within three counties - San Juan, Hinsdale and Ouray - the analytical work extended into a portion of San Miguel County. The resulting mapping and analyses will: 1. Create a spatial foundation to aid future projects in the Alpine Loop corridor; 2. Serve as a prioritization tool for evaluating the conservation potential of individual private parcels; 3. Provide the necessary framework for pursuing future funding opportunities. 2003 2005 Data were retrieved from various sources and analyzed between 2003 and 2005.
