Isotopes - Recolonization of the Cedar River, WA by Pacific salmon

Description

The objective of this study is to quantify population, community, and ecosystem level changes as a result of salmon recolonization of the Cedar River, WA above Landsburg Dam. The dam was installed in 1901, blocking the upstream migration of adult salmon and steelhead from about 43 km of river habitat. A fish ladder was installed in 2003 to allow adult salmon passage. We collected baseline data on water chemistry, habitat, isotopes (periphyton, invertebrates, fish, riparian trees) and resident trout and sculpin populations in 2000-2002. These studies have been ongoing since 2000. A mark-recapture study in Rock Creek, the largest tributary available to salmon, was started in 2004 to quantify growth, movement, and survival of juvenile coho and resident trout. C and N isotope levels in plants, insects and fish in the Cedar River.

0 These data consist of natural abundance levels of C and N stable isotopes in periphyton, in-stream leaf detritus, leaves of riparian plants, benthic invertebrates, and resident fish collected from multiple locations from the main stem Cedar River, and tributaries including Rock and Taylor creeks. Data were collected in 2000 and 2001 to establish baseline conditions before reintroduction of Pacific salmon in 2003. Data were analyzed at the University of Georgia Stable Isotope Facility. https://www.webapps.nwfsc.noaa.gov/apex/parr/cedar_river_n_and_c_isotopes_20002001/data/page/
