GAP distribution models represent the areas where species are predicted to occur based on habitat associations. The distribution models represent the spatial arrangement of environments suitable for occupation by a species. In other words, a species distribution is created using a deductive model to predict areas suitable for occupation within a species range. To represent these suitable environments for this species' habitat distribution model, we used the land cover and other ancillary datasets listed here in this metadata. Details on the habitat affinities and the parameters used to model are provided in the species report in the attached files section of this record.These models can be used to assess the habitat availability across the range of the species and in combination with other data to assess the conservation status or threats to the habitat for the species.
