Description:
Detailed capture- recapture data on larval and neotenic coastal giant salamanders (Dicamptodon tenebrosus) were assembled from 1996 to 2001. These data from 12 streams have been checked and corrected. The primary threat for this species (red-listed by COSEWIC and BC CDC) is considered to be forestry. The sampling design used streams surrounded by oldgrowth, second growth, or recently clearcut forest, so we can consider the impact of forest harvesting on densities, growth rates, movements, survival, and population structure of this species. A preliminary analysis of these data has begun, but requires completion. These data will be the basis of the development of a series of demographic models from which different scenarios can be generated, and population projections derived under different assumptions of threats, risks, and recovery actions. These models will aid the recovery team in their consideration of recovery actions that might be attempted and their potential efficacy.
