FY2017Removal of livestock grazing is a common prescription to promote ecosystem recovery after wildfire (and subsequent emergency site rehabilitation efforts). Ecosystem recovery is typically considered from a terrestrial perspective, but wildfire and grazing can strongly influence aquatic ecosystems as well, especially smaller and fragmented stream networks, which are prevalent in the Great Basin (Minshall et al. 1989[1]; Dunham et al. 2003[2]; Luce et al. 2012[3]). Understanding these influences is essential for managing fire and grazing. Examples include identifying timeframes for resuming livestock grazing following wildfire, and the interactions between livestock grazing, fuels, and recovery of stream-side...
This digital raster dataset represents depth to pre-Cenozoic bedrock in northern Nevada as published in Chapter 6: Geophysical Methods and Application in U.S. Geological Survey Bulletin 2218, Assessment of Metallic and Mineral Resources in the Humboldt River Basin, Northern Nevada by D.A. Ponce. The data are represented on figure 6-9 in this publication and were later provided as raster format geospatial digital data via written communication from D.A. Ponce in 2007. The data have been reprojected but are otherwise as provided. A thorough explanation of the production methods is available in the larger work.
This broad-scale landscape connectivity dataset identifies areas likely to facilitate ecological flow—particularly movement, dispersal, gene flow, and distributional range shifts for terrestrial plants and animals—over large distances and long time periods. Similar to the local permeability analyses (3km radius, Buttrick et al. 2015), this analysis is not species-specific. Rather, it focuses on structural connectivity of natural lands, with resistance to movement modeled as a function of landscape naturalness. This map does not incorporate projections of future climates, nor does it address connectivity for aquatic species. The results identify broad, intact areas where movement of terrestrial organisms is largely...
