Xerospermophilus mohavensis Historic Habitat USRED and Anthro Scale Factors
Summary
Predicted habitat suitability for the Mojave Ground Squirrel (Xerospermophilus mohavensis) after the LOW, MEDIUM and HIGH anthropogenic (urban, roads and cleared vegetation) and utility-scale renewable energy development (wind, solar and transmission corridors) scale factors have been applied. Scale factors are discussed in Inman et al. (2013). These data cover 5 counties (Inyo, Kern, San Bernardino, and Los Angeles) in California and were generated using a maximum entropy (MaxEnt, v3.3.3e) approach. Observation records for the targeted species were derived from a conglomerate of local sources, and are provided electronically along with this model. The model was based on 440 input localities derived from 629 observations of Mojave [...]
Summary
Predicted habitat suitability for the Mojave Ground Squirrel (Xerospermophilus mohavensis) after the LOW, MEDIUM and HIGH anthropogenic (urban, roads and cleared vegetation) and utility-scale renewable energy development (wind, solar and transmission corridors) scale factors have been applied. Scale factors are discussed in Inman et al. (2013). These data cover 5 counties (Inyo, Kern, San Bernardino, and Los Angeles) in California and were generated using a maximum entropy (MaxEnt, v3.3.3e) approach.
Observation records for the targeted species were derived from a conglomerate of local sources, and are provided electronically along with this model. The model was based on 440 input localities derived from 629 observations of Mojave Ground Squirrel. Predicted values were obtained from 100 bootstrap replicates. Modeling was conducted at a scale of 1 km (raster cell size = 1000 m).
This model used 4 environmental variables, which are given below along with heuristic estimates from Maxent of each variable's contribution in parentheses: surface texture (46.6%), summer albedo (25.4%), winter precipitation (16.3%), and winter climatic water deficit (11.7%).
