    • Puget Sound steelhead life cycle model analyses - Population Viability Analysis

    Metadata Updated: October 18, 2025

    This research was initiated by the Puget Sound Steelhead Technical Recovery Team to develop viability criteria for threatened Puget Sound steelhead and to support recovery planning of this species. It involves conventional population viability analysis (PVA) combined with decision support systems such as Bayesian Networks. These systems are parameterized with information on abundance, productivity, spatial structure, and diversity obtained from various sources, including PVAs of individual populations from time-series data of abundance, productivity, age structure, iteroparity, influence of resident fish on anadromous abundance, and influence of human activities such as hatchery production, harvest, and habitat alteration. The work will also focus on assessing status of these listed species every five years as part of NOAA Fisheries' coastwide status review updates for listed salmonids. These data will be outputs from life cycle models developed by the Puget Sound steehead recovery team to evaluate.
