Description

This wildlife status report looks at the eastern short-horned lizard, Alberta's only native lizard species. Scattered populations of these small, well-camouflaged lizards are found on sparsely-vegetated slopes in canyons and coulees in the extreme southeastern parts of the province. The species has been designated as vulnerable in Canada and may be at risk in Alberta. This report was prepared as a review of current information relevant to the determination of the status of this species in Alberta. It is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.

Short-horned lizard (Phrynosoma hernandesi hernandesi) populations in Alberta : 2002 survey results

Short-homed lizards reach the northernmost extent of their distribution in the province of Alberta and are found in relatively small and disjunct sub-populations that are sparsely distributed over... More ≫

Description

Short-homed lizards reach the northernmost extent of their distribution in the province of Alberta and are found in relatively small and disjunct sub-populations that are sparsely distributed over a broad area of the southeastern comer of the province. An effort to search and verify presence of lizards at all sites where they were previously recorded in Alberta was undertaken in July and August of 2001 and 2002. In total, 59 individual sections were searched. Lizards were captured on 19 of these sections. This low number of sections with a verified presence of lizards, in combination with anecdotal evidence, suggests that the overall distribution of this species has contracted within Alberta. Survey effort information from 2001 implies that lizard populations, at the sites that they persist, seem relatively stable.

Description

Field data collection for the Researching Amphibian Numbers in Alberta (RANA) program was initiated in 1997 in response to the global decline of amphibians. RANA has two primary objectives: to collect long-tenn data on amphibian species populations in Alberta, and to provide public education on the importance of amphibians and wetland conservation. This document is a compilation of 2002 field results from the five existing RANA sites at Kananaskis (Bow Valley), Hinton (Athabasca Valley), Lesser Slave Lake Provincial Park, Saskatoon Island Provincial Park, and Manook Biological Research Station near Athabasca.

Description

Short-horned lizards occupy a number of relatively isolated, widely scattered localities within southeastern Alberta. Populations of these small, well-camouflaged lizards are generally of low density and overall abundance in the province, as the area represents the northernmost margin of the species’ range. The objectives of this year's survey were to search all historically recorded locations for the species in the province, to evaluate the probability of continued persistence, given the habitat currently available, and to determine the continued presence of the species by captures where possible. Over the course of the survey, 125 individual lizards were captured. Within those sites found to be occupied by lizards, the average density of captures was also calculated to be approximately two animals per hectare, although southern sites were more generally populous than northern sites.

Description

This wildlife status report looks at the the eastern short-horned lizard, which is Alberta's only native lizard species. Scattered populations of these small, well-camouflaged lizards are found on sparsely-vegetated slopes in canyons and coulees in the extreme southeastern parts of the province. Short-horned lizards have been added to the list of species which may be at risk in Alberta. This report is part of the Alberta Wildlife Status Report series, which provides comprehensive summaries of selected wildlife species intended to be useful to those managing populations of species and their habitats, and to help identify species that may be formally designated as endangered or threatened.
