We sampled terrestrial salamanders in riparian and upland areas within a 40-yold managed forest site in western Oregon. We found 303 ensatinas (0.015 animals/m 2 ) and 14 nests (0.0007 nests/m 2 , 0.05 nests/ensatina) within 20,280 m 2 of forested habitat surveyed. Clutch size averaged 8.3 eggs (range 3 to 11), comparable to previous reports from Washington but lower than reported for California. Of 14 nests found, 11 were in upland forest, Ͼ30 m from streams. Nests were typically on or under
