Collared lizards are monitored closely in the study area, and isolated populations are reconnected by opening the tree canopy in corridors. At top speeds this lizard lifts the forelimbs off the ground and runs on its hind limbs. Glades are treeless or sparsely wooded openings with bedrock at or near the surface. “Red cedar doesn’t resprout after cutting, so we don’t have to apply herbicides to the cut surface of the larger trees.” Some of the other woody vegetation such as redbud (Cercis Canadensis), red oak (Quercus rubra), hackberry (Celtis occidentalis), elm (Ulmus Americana), honey locust (Gleditsia triacanthos) and exotic honeysuckle (Lonicera maackii) resprout following cutting, so a basal bark or cut surface treatment with Garlon 4 Ultra and Bark Oil Blue is applied. Conservation measures taken in Jackson County to reduce the woody canopy have benefited a variety of wildlife including other lizard species and snakes, and reduced invasion of exotic honeysuckle. “Well into the 1960s there were collared lizards in Jackson County, but those populations gradually declined as tree canopy increased,” says Rizzo. DISTRIBUTION: This lizard is distributed across most of central, northeastern, and southeastern Arizona. In our state it occurs at elevations ranging from 1,400' to about 8,500'. The riprap and associated limestone quarry provided safe habitat for a small population of collared lizards that migrated to the disturbed area. Collared Lizard Habitat: These lizards are found in the wide variety of habitats including deserts, sagebrush, pinyon-juniper and desert grasslands. It is often seen basking atop large rocks or boulders in the mid-morning sun. Females heavy with eggs have red spots or bars on their sides and neck. ®™Trademark of Dow AgroSciences, DuPont or Pioneer and their affiliated companies or respective owners.State restrictions on the sale and use of Garlon 4 Ultra apply. REPRODUCTION: The Eastern Collared Lizard lays a clutch of up to 14 eggs in spring or summer. Phoenix, AZ Eggs are creamy white and leathery, and 2–21 are laid in a burrow under a large rock. Unlike many of our lizards collared lizards can not cast off and regenerate the tail. The name comes from the lizards’ distinct coloration, which includes bands of black around the neck and shoulders that look like a collar. Published August 2014; reviewed and revised June 2019.

One theory is that settlers mistook the sound of wind in canyons for the call of an animal in an area where the collared lizard was abundant.

Females are typically varying shades of brown with red markings during the breeding season. Stebbins, R.C. ©2019 Corteva. Like all lizards in our state, this species is active by day, especially when the weather is sunny and warm (73–93°F). The collared lizard is the state reptile of Oklahoma, where it is known as the mountain boomer. The underside is plain and pale. We facilitate and provide opportunity for all citizens to use, enjoy, and learn about these resources. Like other reptiles, lizards thermoregulate or adjust their body temperature by moving to different areas of their environment to warm up or cool down. In pre-European settlement, glades sustained small herds of bison, elk, and deer along with other endemic species uniquely adapted to these particular habitats. Cooler, more shaded habitats caused a decline in lizard reproduction, and dense woodlands formed a barrier to lizard dispersal between glades.
