We are very excited to share that the US Fish & Wildlife Service recently published a paper,”An urban stream can support a healthy population of coastal cutthroat trout” in Urban Ecosystems. They found the characteristics of Coastal Cutthroat Trout in Tryon Creek were similar to populations not influenced by urbanization. Their results suggest that Tryon Creek can serve as an example of a healthy fish population in an urban watershed.
This means that not only can we support fish and wildlife in our urban stream – but our community’s hard work and dedication to habitat restoration, stormwater management, and fish passage removal is WORKING!
