Some Effects of Logging on Two Salmon Streams in Alaska
Abstract:Sedimentation of spawning beds and density of pink salmon (Oncorhynchus gorbuscha) were observed before and after logging in two streams in southeastern Alaska. The study lasted seven years (1958-1964). Although the amount of fine particles in spawning beds increased temporarily, the amount in 1964 (five years after logging began) was not significantly greater than in 1959. Densities of salmon spawners and fry increased in the sampling areas during the period of this study. The increases were probably due to the abolition in 1959 of salmon traps (formerly the primary means of catching salmon).
