About Dataset

The purpose of this report is to summarize information that NOAA’s National Marine Fisheries Service (NMFS) used for evaluating alternative harvest impact limits on the ESA-listed Lower Columbia River Chinook salmon (LCR Chinook) Evolutionarily Significant Unit (ESU). LCR Chinook exhibit life-history types based on adult migration timing, including early fall runs (“tules”), late fall run (“brights”) and spring-runs (reviewed by Myers 1998). The ESU is subdivided into 32 populations, some of which existed historically but are now extinct (Myers et al. 2006) (Figure 1, Table 1). Of the different life-history types, the tules are subject to the highest level of harvest (Kope 2005), and are the sole focus of this report.
