The 2023 Johnson Creek Science Symposium focused on climate change in the watershed, with presentations exploring the past, present, and future. A new addition this year was the panel discussion addressing vegetation management and what we know about how climate change will impact the upland habitat so important to salmon in Johnson Creek. Below are individual presentations. For the full program and present bios, click here.
