Locations and Conditions of Key Habitat

Preferred Habitat

Sagebrush Lizards can be found in association with sagebrush, rocky areas near water, and adjacent areas of fine gravel, sandy, or rocky soil. Areas with boulders, forested slopes, and open flat land with rock crevices or mammal holes will also be used. Although somewhat docile, they will hide under rocks, twigs, or brush piles if alarmed and may occasionally climb trees or bushes. Feed on a variety of insects, spiders, ticks, mites, and aphids.

Key Areas and Conditions for Sagebrush Lizard in North Dakota

Known populations occur in the north unit of Theodore Roosevelt National Park and the badlands near Medora and southward.

Problems Which May Affect this Species

Habitat

Destruction and/or degradation of sagebrush habitat.

Other Natural or Manmade Factors

It is unknown what effect pesticides, development, and other disturbance has on populations of Sagebrush Lizards.

Research and Survey Efforts

Current Research or Surveys

  • There is currently nothing specific to the species in North Dakota

Previous Research or Surveys

  • University of North Dakota studied Climate Change and Land use Effects on Small Mammal Communities in a Northern Great Plans Landscape. This work included herptile surveys.
  • Wheeler and Wheeler (1966) conducted a statewide survey of all amphibians and reptiles, as well as compiled existing records. The skinks were only found in the southeastern corner of the state.
  • Hoberg and Gause (1992) recorded personal observations of prairie skinks in North Dakota.
  • A compilation of all records in North Dakota by Jundt (2000) listed roughly 10 documentations of the Sagebrush Lizard in the state.

Additional Research or Surveys Needed

Future efforts could include visual encounter surveys as the most productive method for determining presence.

Management Recommendations

  • Prevent overgrowth by shrubs and trees to maintain openness in sand habitats.
  • Restrict off-road vehicle use to preselected, less sensitive/lower quality areas.

Monitoring Plans

Currently no monitoring is taking place. Possible monitoring options could include school classes/programs including universities, the general public through the NDGFD incidental reporting system, or national monitoring initiatives such as PARC. Monitoring should be directed at a number of herptile species.

2005-2015 Progress

The Sagebrush Lizard maintains a level III Species of Conservation Priority. More information is needed to understand the status of this species in North Dakota. Work toward a monitoring plan is needed.
