Sagebrush Lizard

A sagebrush lizard is a small, spiny scaled lizard of the American West. It rarely grows longer than 5 to 6 inches, tail included. Its scientific name is Sceloporus graciosus, and it shares its genus with the western fence lizard and eastern fence lizard.

A separate, more range restricted relative also carries the sagebrush name. The dunes sagebrush lizard, Sceloporus arenicolus, was federally listed as endangered in 2024. Neither species is a pet trade animal.

This guide covers what the common species looks like and how to tell it from a fence lizard. It also covers where it lives, what it eats, and how it breeds. Finally, it covers the law around the protected dunes species and what “keeping” one really means.

Size and lifespan

Adults measure about 2 to 3.5 inches from snout to vent. The tail adds another 2 to 2.5 inches. Total length usually falls between 4 and 6 inches, one of the smallest builds in the genus Sceloporus.

Hatchlings emerge at under an inch long. They grow quickly through their first summer of feeding. By the following breeding season, most survivors have reached adult size.

No state agency account gives a wild lifespan figure for this species. Similarly sized relatives, like the western fence lizard, commonly live 5 to 7 years in the wild. Few individuals of any small Sceloporus ever reach that age.

Most mortality happens in the first year of life. Small lizards like this one face heavy pressure from birds, snakes, and mammals. Growth and lifespan both track closely with elevation and local climate.

Populations at higher, colder sites mature more slowly. In California the active season runs from March or April to late September or early October, and juveniles stay out later into fall than adults. For general context on how lifespan varies across species, see this lizard lifespan guide.

Identification: sagebrush lizard vs fence lizard

Sceloporus graciosus is easy to confuse with the far more common western fence lizard. Both are gray to brown and spiny scaled. Both bask on rocks and logs across much of the same region.

Two field marks separate them reliably. It has noticeably smaller, finer dorsal scales than a fence lizard, and three pale stripes usually run down the back. Most also show a patch of rust or orange skin tucked into the armpit, just behind the front leg, that fence lizards lack.

Belly color will not help much. Males of both species flash blue patches on the throat and belly during the breeding season. Overall size is also a weak clue, since young fence lizards overlap in size with adults of this species.

A third small basker sometimes shares the same ground. The side blotched lizard is smaller still and has smooth, not spiny, scales.

For a side by side look at the more common cousin, see the full western fence lizard profile. The eastern fence lizard shares the same spiny build but lives well outside this range.

Range and habitat

Sceloporus graciosus ranges across the interior western United States. That includes Washington, Oregon, California, Nevada, Utah, Idaho, Wyoming, Colorado, Arizona, and New Mexico. It favors open sagebrush flats above almost any other habitat.

It also turns up in pinyon juniper woodland and open ponderosa pine forest. Douglas fir clearings work too, as long as there is bare ground and low cover nearby. Loose, sandy or gravelly soil lets it dig shallow burrows and slip under rocks to escape heat.

Elevation range is wide. California’s wildlife agency puts the species at 900 to 3,200 meters (3,000 to 10,400 feet) there, from montane chaparral to conifer forest openings, while Great Basin populations sit lower on valley floor sagebrush. The wider family of spiny iguanid lizards that includes Sceloporus covers a similar spread of arid habitat across the Americas.

The dunes species

This dune specialist is a distinct species with a tiny range. It lives only on active sand dunes in southeastern New Mexico and west Texas, centered on the Mescalero and Monahans Sandhills. It depends on shinnery oak, a low scrub oak that holds the dunes together, and it forages in open bare sand between the oak clumps.

The listing rule sets a hard habitat threshold. Once mesquite cover passes about 10 percent in New Mexico or 5 percent in Texas, the dunes lose their structure and the lizard drops out. Breeding has never been recorded outside shinnery oak duneland.

Its entire known range covers only a few hundred square miles. All of it sits inside the Permian Basin, one of the most heavily drilled oil and gas regions in the country. That overlap between a tiny habitat and intensive drilling is the core of its conservation story.

The US Fish and Wildlife Service first proposed protecting it in 2010. It withdrew that proposal in 2012 after Texas and New Mexico adopted voluntary conservation agreements with landowners. A new proposed rule followed in 2023 as habitat loss data mounted.

On May 20, 2024, the agency published a final rule. It listed Sceloporus arenicolus as endangered under the Endangered Species Act, effective June 20, 2024. The listing cites habitat loss from well pads and roads, frac sand mining that began in the region in 2017, and drought tied to climate change.

Behavior

These lizards are active by day. They spend much of their time perched on rocks, logs, or a shrub base, watching for insects and rivals. They rely on quick bursts of speed rather than long chases.

At the first sign of a hawk, shrike, or snake, it darts for cover. That usually means the base of a shrub or the mouth of a burrow. Basking closely tracks temperature through the day.

Lizards retreat to shade once midday ground temperatures climb too high. They bask again once temperatures ease in the late afternoon. Males defend territories up to about 7.5 meters (25 feet) across with push up displays, head bobs, and outright combat.

Home ranges are tiny. Maximum recorded movements in a year average 24 meters for males and 18 meters for females, and some pairs stay together across seasons.

Activity slows sharply with the season. In colder, higher parts of the range, they brumate underground through winter. They emerge again once soil temperatures rise in spring.

Diet in the wild

These lizards are opportunistic insectivores that feed almost entirely on small arthropods, with ants and beetles making up the largest share. Other documented prey includes flies, caterpillars, aphids, spiders, scorpions, ticks, and mites. Most of it is picked off the ground, low vegetation, and leaf litter near a basking perch.

They forage mainly by sight. A lizard waits on a perch, then ambushes prey that moves within range. It supplements that with short active searches through shrub bases and loose soil.

Diet shifts somewhat with local prey availability. A lizard in dense shinnery oak dune habitat meets a different insect community than one on an open sagebrush flat. There is no legal pet trade diet to describe here, since keeping either species is not a normal option.

See the care and legal status section below for why. For general background on how wild and captive lizards feed, see this guide to lizard diets.

Breeding

Breeding runs from late May through August, depending on latitude and elevation. California accounts put egg laying in June or July, while Washington records the season as June through August. Females lay one or two clutches per season.

Each clutch goes into a nest a few centimeters deep in loose soil, usually near a shrub base. Clutches hold 2 to 8 eggs, with the largest females laying the most. Incubation takes around two months, and hatchlings emerge from mid August to late September.

Eggs laid early in the season hatch in time for young lizards to feed and grow before cold weather sets in. Clutch size tends to scale with the size and condition of the female. It also scales with how favorable that year’s temperature and rainfall have been.

Hatchlings get no parental care after emerging. They must find their own food and cover right away. Heavy predation and exposure risk are the main reasons clutch sizes stay large for such a small lizard.

Legal status and “care”

Neither species on this page is a legitimate pet. Sceloporus graciosus is a native wild species everywhere it occurs. Most western states regulate or flatly prohibit collecting native reptiles without a scientific or educational permit.

Check the specific state wildlife agency before assuming any native lizard can be picked up and kept. The dunes species is now federally listed as endangered. Under the Endangered Species Act, capturing, harming, or possessing a wild one without authorization is illegal.

Violations carry real penalties. There is no legal path for a private individual to keep one as a pet. What responsible “care” means here is conservation, not husbandry.

That means protecting shinnery oak dunes and sagebrush habitat from unnecessary disturbance. It means reporting sightings to state wildlife agencies or citizen science databases. It means supporting habitat focused agreements rather than removing animals from the wild.

A licensed zoo, museum, or research collection may hold specimens under permit for education or study. That housing follows the general standards below.

Enclosure notes for licensed institutions

Where a permitted zoo or research facility does keep one, housing mirrors open, arid habitat rather than a tropical terrarium. A single adult typically gets a floor footprint of 2 to 3 square feet of usable ground. Substrate is loose sand or gravel, deep enough to allow shallow digging.

Furnishings include flat basking rocks, low shrub branches, and one or two hides. A clear temperature gradient runs from a warm basking spot to a cooler, shaded retreat. Since this species is a fast, ground focused runner rather than a climber, floor space matters more than height.

This information describes institutional husbandry standards, not a home care setup. No legal retail source for either species exists.

Heating and lighting

In the wild, this species regulates body temperature entirely through basking and shade seeking. They move between full sun and cover as ground and air temperatures shift through the day. A permitted institutional setup copies that gradient.

A basking surface usually reaches roughly 95 to 100 degrees Fahrenheit. The cooler end sits in the mid 70s, letting the animal choose its own preferred spot. UVB lighting across the ultraviolet range is standard for any diurnal, sun basking lizard kept under permit.

Ambient temperature should drop at night, matching cool desert and montane nights across its natural range. Institutions that choose to breed the species often add a winter brumation period at lower temperatures. That mirrors its wild seasonal cycle.

Health and threats

In the wild, the biggest threats are predation, habitat loss, and, for the dunes species, industrial development. Predatory birds and snakes take the most, with striped whipsnakes and night snakes singled out in California accounts. Young lizards face the heaviest losses in their first year.

Habitat degradation from grazing and invasive grass encroachment chips away at sagebrush and pinyon juniper habitat across the broader range. Its wide distribution keeps the common species listed as a species of least concern overall. This dune specialist has no such buffer.

Its entire population sits inside one drought prone, heavily drilled region. That is exactly why it moved to endangered status in 2024. Anyone who finds an injured or sick lizard of either species should contact a state wildlife agency or a licensed reptile veterinarian rather than attempting home treatment.

Cost

There is no purchase price to quote for either species. Neither is sold through the legal pet trade. Any listing offering either lizard for sale should be treated as a red flag.

That could mean mislabeled captive bred fence lizards. It could also mean an outright illegal wildlife transaction. The real costs tied to these species are conservation costs.

Habitat restoration, oil and gas mitigation agreements, and the permitting and monitoring that come with an Endangered Species Act listing all cost money. Agencies, landowners, and industry bear those costs under the conservation agreements tied to the dunes lizard’s protected status. Hobbyists play no part in it.

Frequently Asked Questions

Is a sagebrush lizard the same as a fence lizard?

No. They are closely related Sceloporus species with similar coloring and basking habits. The smaller species has finer dorsal scales, rust colored armpits, and a narrower habitat preference for sagebrush and open woodland.

Can you legally own a sagebrush lizard?

Sceloporus graciosus is a native wild species, and most states restrict collecting native reptiles without a permit. The dunes species cannot legally be captured or kept at all without federal authorization, since it was listed as endangered in 2024.

Why was the dunes species listed as endangered?

The US Fish and Wildlife Service cited habitat loss from oil and gas development and frac sand mining across its small dune range. Drought linked to climate change made the case stronger. The final rule was published on May 20, 2024.

What do sagebrush lizards eat?

Almost entirely small arthropods, especially ants and beetles, plus flies, caterpillars, aphids, spiders, scorpions, ticks, and mites. Most prey is caught by ambush near a basking perch.

How big do sagebrush lizards get?

Adults measure roughly 2 to 3.5 inches from snout to vent. Total length, including the tail, usually falls between 4 and 6 inches.

How long do sagebrush lizards live?

No state wildlife account publishes a lifespan for this species. Similarly sized relatives like the western fence lizard typically live 5 to 7 years, and survivors of the first year likely fall in a comparable range.
