In response to petitions for listing different cutthroat species under the Endangered Species Act, an effort began in 2001 to develop range-wide status assessments for each subspecies of cutthroat trout. To assist in the capture and management of this vast amount of information, a standardized geospatial data model was developed to accurately describe the spatial location and extent of a stream or lake currently occupied by cutthroat trout, and also provide specific descriptions of their abundance, relative habitat quality, genetic purity and the size of the meta-population. Each of these attributes, in conjunction with estimated historically occupied habitat, allowed for objective, quantifiable assessments of the health of a species of cutthroat. To date Greenback, Colorado River, Rio Grande, Bonneville, Yellowstone, Westslope, and Lahontan cutthroat have completed the process of populating the ICP database. Due to the complexity of this data, several tools have been developed to maximize use of the ICP databases, such as a Data Viewer which provides a GUI interface to the underlying data and a Data Editor which allows users to adjust stored values while maintaining data integrity rules.
Using the ICP (see above), Redband trout (Oncorhynchus mykiss spp.) data will be compiled into the standardized database format. This project is set to begin January 9, 2012 in which 12 individual workshops will be held with each workshop lasting between 3 and 5 days. At each workshop, State, Federal and Tribal biologists work in conjunction with a GIS specialist. Using the NHD 24k stream and lake data, their goal is to identify all water bodies historically and currently occupied by the resident-form of Redband Trout and describe the attributes for each location. The data from each workshop will then be compiled into a single geodatabase and a Status Assessment describing the relative health of the species will be completed. The project completion date is scheduled for December 2012.
