The Tiger Salamander in British Columbia: An Amphibian in an Endangered Desert Environment (in Proc. Conference Biology & Management of Species and Habitats at Risk) Richardson, John S.

Abstract: The Red-listed tiger salamander (Ambystoma tigrinum melanostictum) is found in a limited range in the South Okanagan, where it is subject to large-scale habitat alienation. We studied a series of 10 ponds to determine larval growth rates, juvenile recruitment, movement of adults to and from breeding ponds, and terrestrial habitat use by adults during the summer. Ponds varied in the rate of larval growth, size at metamorphosis and timing, and the number of new recruits. Two of the most productive ponds were shallow and most susceptible to drying prior to larval development, indicating that the productivity of a given pond may vary from year to year. Through the summer months adult tiger salamanders did not move >150 m from the pond where they were captured, and used open sagebrush-grassland habitats. In this arid environment they did not select dense cover or mesic sites, and likely avoided dehydration by entering small mammal burrows.
