—Pitfall traps effectively sampledamphibians but not reptiles in Douglas-fir(Pseudotsuga menziesii) forests. The abundance ofonly one amphibian species varied across an agegradient or a moisture gradient. Salamanders andfrogs that breed in ponds or streams were capturedin large numbers in some stands, likely due to thepresence of nearby breeding habitat rather thanforest conditions. Lizards occurred mostly in drystands and clearcuts. lime-constrained searchesshowed different use of downed woody debrisamong terrestrial salamanders. The occurrence andabundance of species in naturally regeneratedforests markedly differed from clearcut stands.
