Climate Change and Salmonids

Understanding how species and habitats are likely to respond to climate warming is critical in developing effective conservation and management strategies for freshwater ecosystems.This is particularly true for salmonids, which are culturally and economically critical keystone species and excellent indicators of ecosystem health since they are sensitive to altered stream flows and temperatures related to ongoing climate change. Unfortunately, owing to a century of habitat change or loss, hatchery operations, and misguided harvest management, salmonid populations are declining.

Future climate changes, such as warming stream temperatures and changing hydrological regimes may compound existing stresses to salmonids.

Relatively conservative projections of climate change over the next 100 years indicate the potential for climate warming of 3-5°C and annual precipitation changes up to 20% within Pacific salmon habitat.

This Decision Support System (DSS)  is designed to respond to  and inform the myriad of questions surrounding risks to salmonids under a changing climate.

The integrated DSS provides several modules to provide data, information, and tools to support research and inquiries concerning potential climate change  effects on salmonids.
