Title: An analysis of the effects of riparian forest harvest on instream wood recruitment as proposed by the Idaho Forestry Program for state and private timberlands in the Clearwater and Salmon River Basins

Institution: Report of the NMFS Northwest Fisheries Science Center to the NMFS Idaho State Habitat Office
Date: April 1, 2013

 The National Marine Fisheries Service Idaho State Habitat Office requested that the Northwest Fisheries Science Center review a proposed plan for timber harvest in forests along streams (riparian forests) to assess what effects the proposed timber harvest would have on the future abundance of wood in streams. Wood that falls into streams affects sediment transport processes and stream hydraulics such that it creates habitat important to juvenile and adult salmonids for spawning, rearing, egg incubation migration and overwintering. The importance of instream wood to salmonids has been reviewed extensively elsewhere and is not discussed further in this analysis. The riparian timber harvest rules were proposed by the Idaho Forestry Program (IFP) and the proposal is being reviewed by NMFS in the context of Section 7 of the Endangered Species Act.
