Computer Terrain Mapping, Inc. 2005 map The Alpine Loop Landscape-Based Conservation Priorities (LBCP) data set shows the combination of the resource value mapping and the development potential mapping. The conservation priorities are referred to as landscape-based because they focus predominantly on the naturally occurring systems - i.e., topographic, vegetative, geologic, etc parameters - largely separate from the human imposed land ownership pattern. Resource value and development potential are combined to form the landscape-based conservation priorities. These are areas of the landscape with high conservation value that are likely to be developed without violating building constraints and local government regulations. Note that at this point, development potential has not been restricted to private parcels. The results of the landscape-based analysis are then combined with the land ownership pattern to define the overall conservation priorities. 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.

GRASS version 5 on Red-Hat Linux version 8.0 exported to an ASCII Grid LBCP was determined from a variety of data sources of unknown accuracy. Data are calculated from a variety of data sources of unknown accuracy. Only basic spot checking based on knowledge of terrain was performed. LBCP was calculated for the entire study area. Computer Terrain Mapping, Inc. 2005 Map digital 2003 2005 Data were retrieved from various sources and analyzed between 2003 and 2005. Conservation Resource Value Intrinsic conservation value of an area. Computer Terrain Mapping, Inc. 2005 Map digital 2003 2005 Data were retrieved from various sources and analyzed between 2003 and 2005. Development Potential Generalized development potential for an area, that is, suitability for residential development. After adjustments for differences in the total range of values for the conservation resource value and development potential maps, these were combined to form the landscape-based conservation priorities. To emphasize management toward resource protection, we assigned the resource value map twice the weight as the development potential map (i.e., we multiplied the resource map by two before adding the development potential map). The result contained 81 categories, with higher values representing higher priorities.
