Liolaemus hellmichi is listed as Vulnerable due to the small number of adult individuals that occur within its very small range. Complete censuses of the range of the species never record more than 13 individuals. Given what is known about the density of congeners in similar desert habitats, the entire adult population cannot be more than 500 individuals.

Population [top]

Population:This species is rarely encountered within its very restricted area. The lack of threats suggests that the population is stable. It was recorded as recently as 2015 (Y. Marambio unpubl. data 2015).

Censuses of the entire range of the species between 1988 and 2015 have never recorded more than 13 individuals (range: 1-13). Although the detection probability is unknown, these observations infer that the entire population size must be less than 500 individuals in such a small area (approx. 125 ha) (P. Espejo, J. Mella, Y. Marambio, J. C. Ortiz, M. Ruiz de Gamboa unpublished data).
Current Population Trend:Stable
Additional data:
Number of mature individuals:499Continuing decline of mature individuals:Unknown
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is found in coastal desert habitats where coastal mist provides some moisture. Vegetation includes cacti and other sparse xerophytic species. It feeds on arthropods (Pincheira-Donoso et al. 2008).
