Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Reptilia Squamata Liolaemidae

Scientific Name: Liolaemus walkeri Shreve, 1938
Taxonomic Notes: Records from Chile previously attributed to this species have been described as a separate taxon, Liolaemus puna.

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2017
Date Assessed: 2014-02-25
Assessor(s): Aguilar, C. & Perez, J.
Reviewer(s): Bowles, P.
Contributor(s): Hanson, S.
Facilitator/Compiler(s): Rodríguez, J. & NatureServe
Justification:
Listed as Near Threatened because although its distribution shows fragmentation but not severely, it has an extent of occurrence of approximately 8,000 km2, and while mining activities and overexploitation for alternative medicine purposes in several locations are decreasing the area and quality of its habitat and possibly the number of mature individuals the impact of threats is presently poorly-known and somewhat speculative, the species is locally common, and it is not clear that the species occurs at fewer than ten locations as threats presently appear localized. As such it is close to qualifying for a threatened listing applying Criterion B.

Habitat and Ecology [top]

Habitat and Ecology:It is known from Puna habitats, where it has been observed under rocks. It is a viviparous species (Aguilar et al. 2013).
Systems:Terrestrial

Use and Trade [top]

Use and Trade: In some localities there is some exploitation for alternative medicine purposes.

Threats [top]

Major Threat(s): It is affected by localized threats like overexploitation for alternative medicine purposes, urban growth and mining activities. The mining activities may also present a danger to animals' health, due to water, soil, and air pollution. The species may be affected by global warming because it needs lower temperatures for embryo development, and this threat may increase the female's body temperature (C. Aguilar pers comm. 2014).

Conservation Actions [top]

Conservation Actions:

There are no known species-specific conservation measures in place for this species. This species would benefit from better information on distribution, abundance, population trend, evolutionary studies, education and awareness to reduce the use of the species for alternative purposes, and threats.
