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

1 - Listed endangered or threatened -or- No open season in Arizona -or- Has a signed CCA, CCAA, Conservation Strategy and Assessment or Strategic Conservation Plan -or- Is covered under the Bald/Golden Eagle Protection Act

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

1 - Demographically poor situation: Unusually low birth rates or high death rates combined with small or declining population size; demographic rates are affected by known stressors likely causing a worsening situation in parts of Arizona

Concentration Status

2 - Does not meet the criteria

Distribution Status

2 - Does not meet the criteria
