Description
- Abstract: In November 2003, the State of Oregon began a comprehensive review of coho and their habitat in NOAA Fisheries’ Oregon Coastal coho Evolutionary Significant Unit (ESU). The purpose of the review is threefold: 1) provide an analysis of the current status and trend in coho populations, their habitat, and related threats; 2) provide NOAA Fisheries with information it requires to determine whether formalized conservation efforts within the ESU justify not listing coho under the Endangered Species Act as outlined in their Policy for Evaluation of Conservation Efforts; and 3) provide information to state agencies, watershed councils, and others participating in the Oregon Plan for and Watersheds (OPSW) so they may assess the success of their OPSW programs and modify them where necessary to better achieve their objectives (i.e. adaptive management). This report describes the current status and trend of instream physical habitat for coho in the ESU as well as summarizes and evaluates instream habitat restoration activities conducted from 1997-2003.
Persistence of coho salmon populations in coastal drainages during periods of poor ocean conditions is dependent on the distribution and carrying capacity of freshwater habitat. Coho salmon are sensitive to the quality of habitat during each life stage and seasonal effects on survival are propagated through subsequent life stages (Nickelson et al. 1992). In this chapter, we use measures of habitat quality and quantity to determine overall carrying capacity of freshwater habitat at two juvenile coho life stages: 1) fry through summer parr; and 2) over-winter parr to smolt. From this information we identify life stages at which habitat may limit the coho smolt production capacity for the coho salmon populations considered independent by NOAA Fisheries Technical Recovery Team.
