Sonorella rooseveltiana fragilis Roosevelt Talussnail
SGCN Tier 2
Habitat Suitability Model
Habitat suitability models were generated at 30 m2 resolution. The map below aggregates predicted suitable habitat into 1 mi2 hexagons. The color of each hexagon represents percentage of 30 m2 pixels predicted to be present over the total number modeling pixels in each hexagon.
Habitat Suitability Models do not necessarily indicate the presence of a species in any particular location.
More information about the model can be found in the model metadata.
