Chapter Seven. Forestry and anadromous fish

Abstract

The relationship between forest practices and anadromous fish production has continued to be debated during the intervening decades without a clear resolution. The issue is complicated because there are activities in addition to forest practices that affect anadromous fish production. The offshore fishery removes a large portion of those adults that would return to the streams to spawn. Instream fishing removes another portion of those spawners. Dams on the rivers reduce peak streamflows that influence channel morphology and sediment transport, as well as modify low-flow discharges in the summer. Much of the downstream river habitat is modified by major highways, agriculture, and urbanization. Estuarine habitat has been virtually eliminated from many rivers and severely modified for the remainder
