Climate Change

Declining populations & stress

Trout and salmon will not weather climate change without our help.


Coldwater species have evolved and adapted to changing conditions over thousands of years. But given the declines in populations and the continuing stresses they are already facing, they will not weather climate change without our help.

Trout Unlimited’s work addresses climate impacts by focusing on the health and resiliency of streams and rivers. Reducing flood (FEMA culvert work) and fire damage is a priority and minimizes the negative impacts on communities surrounding coldwater habitats.

Protect stronghold populations


By protecting and expanding stronghold populations in waters most likely to weather climate change, we can improve the odds for trout and salmon.

Reconnect segmented habitats


Removing obsolete dams, installing fish ladders, increasing in-stream flows, and replacing road culverts allows fish to reach thermal refuge during summer heat spells, fires, and drought. Additionally, work in New England has also reduced the risk of blowouts by replacing undersized culverts with bridges.

Recreate a habitat’s natural features


By creating structures that mimic beaver dams and restoring wet meadows, we reconnect streams to their floodplains, buffer the effects of fire, and enhance habitat.

Restore streamside vegetation


By restoring streamside vegetation, we keep temperatures cooler and waters healthier.
