Catostomus discobolus Bluehead Sucker
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.
Fish models are visualized with a single color for visual clarity.
SGCN Score
The following scores are based on a vulnerability analysis AZGFD performed for each species. These scores determined SGCN status. For more information, refer to Chapter 1: Arizona's Biodiversity.
Extirpated Status
2 - Does not meet the criteria
Federal or State Legal Status
2 - Does not meet the criteria
Declining Status
2 - Does not meet the criteria
Disjunct Status
1 - Disjunct population: one to few populations in Arizona separated by large relative distance from larger core distribution of the species outside of Arizona -or- Isolated populations: the core of the species range is within Arizona, and consists of one to few populations that are separated by relatively large distances from one another
Demographic Status
2 - Does not meet the criteria
Concentration Status
2 - Does not meet the criteria
Distribution Status
2 - Does not meet the criteria
