Abstract:

Substrate composition and the availability of suitable cover are known to strongly influence salamander distribution and abundance. Experimental additions of cover objects, resulting in increased salamander densities, demonstrate that cover objects may be a limiting resource in a variety of habitats. Here, the author describes the relationship between cover density and the density of stream-dwelling larvae of the pacific giant salamander, Dicamptodon tenebrosus (formerly D. ensatus), in a headwater stream in northwest California.
