A stratified systematic sampling design was used to quantify the habitat relationships of the Del Norte salamander in northwestern California. [All sample sites occurred within the drainages of the Smith, Klamath, and Trinity rivers on public lands from near the Oregon border south to north central Humboldt and Trinity counties, and east from the Pacific Ocean to western Siskiyou and Trinity counties.] We sampled 57 sites, each within at least 5-7 ha of relatively homogenous forest or post-forest habitat, where we measured 83 characteristics of the environment. Salamander sampling consisted of area-constrained sampling of 7x7m plots with at least 25% rock cover at each site. A subset of 43 variables was used in a hierarchical analysis of habitat associations using discriminant analysis and regression. Variables included attributes at the landscape, macrohabitat, and microhabitat scales.
