IUCN Red List Category: LC - Least concern

NatureServe Global Conservation Status Factors

Range Extent: 200,000-2,500,000 square km (about 80,000-1,000,000 square miles)
Range Extent Comments: The range extends from southern New Mexico to central Texas, and south to Zacatecas, Mexico (Degenhardt et al. 1996, Bartlett and Bartlett 1999, Dixon 2000, Stebbins 2003). Elevational range: 1,000-9,245 feet (300-2,818 meters) (Degenhardt et al. 1996, Stebbins 2003).

Number of Occurrences: 81 to >300
Number of Occurrences Comments: This species is represented by many occurrences. Degenhardt et al. (1996) mapped more than 100 collection sites in New Mexico alone. Dixon (2000) mapped its occurrence in three dozen counties in Texas.

Population Size: 10,000 - 1,000,000 individuals
Population Size Comments: Total adult population size is unknown but surely exceeds 10,000 and very likely exceeds 100,000. The species can be common in suitable habitat (Bartlett and Bartlett 1999).

Overall Threat Impact: Low
Overall Threat Impact Comments: No major threats are known.

Short-term Trend: Relatively Stable (<=10% change)
Short-term Trend Comments: Extent of occurrence, area of occupancy, and population size are substantial and probably are relatively stable.

Long-term Trend: Decline of <30% to increase of 25%

Intrinsic Vulnerability: Moderately vulnerable

Ecology & Life History
Help
Reproduction Comments: Gives birth to litter of 6-23 young, June-July. Sexually mature in second year (Ballinger 1973).
Ecology Comments: Annual mortality: newborn (86%), yearlings (54%), adults (57%) in Texas (Ballinger 1973).
Non-Migrant: Y
Locally Migrant: N
Long Distance Migrant: N
Palustrine Habitat(s): Riparian
Terrestrial Habitat(s): Bare rock/talus/scree, Cliff, Desert, Woodland - Mixed
Special Habitat Factors: Burrowing in or using soil, Fallen log/debris
Habitat Comments: This lizard occupies rocky canyons, gullies, hillsides, and outcrops in largely barren areas, mesquite grassland, creosote bush desert, arid woodland (e.g., oak/pinyon pine/juniper), and spruce-fir forest (Degenhardt et al. 1996). It is invariably closely tied to rocks and seeks shelter in crevices (Degenhardt et al. 1996, Stebbins 2003).
Adult Food Habits: Invertivore
Immature Food Habits: Invertivore
Food Comments: Eats insects, spiders, and occasionally plant material (Stebbins 1985).

Population/Occurrence Delineation

Group Name: Phrynosomatid Lizards

Use Class: Not applicable
Minimum Criteria for an Occurrence: Occurrences are based on evidence of historical presence, or current and likely recurring presence, at a given location. Such evidence minimally includes collection or reliable observation and documentation of one or more individuals (including eggs) in or near appropriate habitat where the species is presumed to be established and breeding.
Separation Barriers: Busy highway or highway with obstructions such that lizards rarely if ever cross successfully; major river, lake, pond, or deep marsh; urbanized area dominated by buildings and pavement.
Separation Distance for Unsuitable Habitat: 1 km
Separation Distance for Suitable Habitat: 5 km
Separation Justification: Phrynosomatid lizards have small home range sizes, usually less than 0.5 ha (often much less) and rarely more than 1 ha (see examples in BCD EO Specs). In a study that documented exceptionally large home range size for a phrynosomatid, Munger (1984a) found that single-season home range size of Phrynosoma cornutum in southern Arizona averaged less than 2.5 ha. Dispersal distances are poorly known, and most studies have not been designed to detect long distance movements. The separation distance for suitable habitat is a compromise between the typical sedentary habits of these lizards, their physical ability to cover fairly large distances in a short period of time, their tendency to occur throughout patches of suitable habitat, and the likely low probability that two occupied locations separated by less than several kilometers of suitable habitat would represent independent populations.
Inferred Minimum Extent of Habitat Use (when actual extent is unknown): .2 km
