Event Title
From the molecular to population risk to ecosystem services: a risk assessment adaptive management approach for the Salish Sea
Presentation Abstract
An ongoing issue in the management of the Salish Sea is the dilemma of how to integrate different scales of information into an adaptive management program to ensure restoration and protection of the resource. Often, we have data on chemical contamination in the environment and exposure to the individual, information on habitat quality, and some general information on population dynamics of a species serving as a vital sign. However, this information is not tied together with a clear and quantitative model describing causality, probability and uncertainty. Furthermore, the goal is not just to preserve that species but to protect human well-being. Human well-being has become part of the lexicon to included ecosystem services endpoints such as a sense of place, education, recreational opportunities, employment, public safety and Tribal treaty rights. In a recent publication (Harris et al. 2017) it was demonstrated that it is possible to estimate risk in a contaminated site to ecological endpoints, human health and ecosystem services using a clearly defined causal pathways and Bayesian networks. Now we are applying the integration of ecological endpoints, ecosystem services and human well-being to the scale of the Salish Sea using specific watershed and coastal regions as models. In this study we are using Skagit, the Nooksack and the Cedar watersheds as case studies. Valerie Chu and Chelsea Mitchell (this session) have described the assessment methodologies and our modeling results for these watersheds. The vital sign is also tied to specific economic ecosystem services, is important to a sense of place, and are valued by the diverse constituencies in the region. We will demonstrate how the Chinook salmon population risk model can be translated as risk to a variety of ecosystem services contributing to human well-being. These outputs then become part of a larger adaptive management program for the system.
