We surveyed first-order streams in forest stands 0-94 yr old on industrial timberlands in the Cascade Mountains of southern Washington, USA, during the summer of 1998 and 1999 to determine how short-term changes in forest age can affect the abundance of the stream-breeding Cope's (Dicamptodon copei) and Pacific giant (D. tenebrosus) salamanders. Based on results from cross-validated regression trees, densities of both species were unrelated to changes in forest age or any other habitat variable measured. There was also no difference in any of the measured habitat variables between streams in which a species was present and streams in which it was not detected. However, densities of the Pacific giant salamander were negatively correlated to percent of riparian canopy cover in one of the years.Steele et al "Influence of forest age on densities of Cope's and Pacific giant salamanders."
