Geometry Type: null

Description: This is a MaxEnt (v. 3.3.3e) inductive model. Environmental Inputs used are listed below. The state of Colorado was the modeling extent. Colorado Natural Heritage Program (CNHP) Element Occurrence Records (EORs) were used as known locations for the species. Initial cut-off of 0.295 was deemed too low, so that model results with a value of 0.7 or greater were retained for use in Marxan, based on model logs and expert review. The output extent was not modified (no mask was necessary to limit extent to known range). This model has been reviewed by Colorado zoology and wildlife professionals. The model is based on 63 EORs and 646 Observations, which were translated into 846 input points. 631 input points used for training, 157 for testing. Training AUC is 0.883, test AUC is 0.879 Environmental Inputs (variable importance): * Distance to water (37.8%) * Elevation (31.7%) * Vegetation type (16.2%) * Distance to wetlands (10%) * Landform (4.3%)
