About This Project
The Bureau of Land Management's Greater Sage-Grouse Northeast California-Nevada Sub-Regional Planning Team requested assistance with spatial, quantitative assessment of a series of management alternatives. This work was desired to contribute to the Environmental Impact Statement (EIS) for the greater sage-grouse (Centrocercus urophasianus) in Nevada and northeastern California. In addition to characterizing the impacts of these alternatives on greater sage-grouse and its habitat, BLM also needed to understand how these alternatives might affect program areas such as oil and gas development, renewable energy development, livestock grazing, and other managed land uses. NatureServe Vista was used to build a series of scenarios representing the three management alternatives and a climate change scenario, and then to evaluate the effects of these scenarios on sage-grouse habitat and other natural and programmatic resources of interest.
The goals of this assessment were:
- To provide a transparent decision-support system that can analyze multiple management alternatives and inform the selection of the preferred alternative for the Northeastern California–Nevada Greater Sage-Grouse Environmental Impact Statement. Vista software provided the BLM a way to more easily document the science, expert knowledge, and resource trade-offs used in decision making. Vista will also allow anyone to recreate the analyses used by BLM.
- To quantify the areal implications of three management alternatives and a climate change scenario on greater sage-grouse and BLM program areas (such as oil and gas development, renewable energy, and others) and provide both map and quantitative summaries of the analysis results.
