Description

Abstract: NOAA Technical Memorandum NMFS-NWFSC-42 This document introduces the viable salmonid population (VSP) concept, identifies VSP attributes, and provides guidance for determining the conservation status of populations and larger-scale groupings of Pacific salmonids. The concepts outlined here are intended to serve as the basis for a general approach to performing salmonid conservation assessments. As a specific application, the VSP approach is intended help in the establishment of Endangered Species Act (ESA) delisting goals. This will aid in the formulation of recovery plans and can serve as interim guidance until such plans are completed. The approach of the VSP concept and this document is to define a viable population, describe techniques for determining population boundaries, identify parameters useful in evaluating population viability and then set guidelines for assessing population viability status with regard to each of the parameters. Finally guidelines are provided on how to relate individual population viability to the viability of the Evolutionarily Significant Unit (ESU) as whole. The document is based primarily on a review and synthesis of the conservation biology and salmonid literature. A large portion of the document is an appendix devoted to describing the technical rationale behind the population definition and viability guidelines.
