The Cascadia Bioregion is a vast area spanning from Northern California to Southern Alaska that encompasses diverse landscapes, vibrant cultures and countless regenerative initiatives. Within this expansive bioregion lies the Salish Sea, a unique and ecologically rich inland sea bordered by the coastlines of British Columbia and Washington State. The Salish Sea, a critical waterway for marine life, serves as a hub for both local communities and migratory species, from orcas to salmon. Nested within this broader region is the Cedar River/Lake Washington Watershed, a vital freshwater system that provides water to the greater Seattle area and supports important habitats for fish, wildlife, and plants.

These interconnected ecosystems form a delicate balance, where the health of one affects the well-being of the others, making climate resilience efforts in each area crucial to maintaining the region’s overall environmental integrity.

A wide range of organizations and networks are actively working to regenerate the landscapes within the Cascadia Bioregion, from restoring salmon habitats in the Salish Sea to revitalizing the forests, watersheds and urban communities nestled in the Cedar River/Lake Washington watershed. These efforts include everything from large-scale conservation programs to community-based initiatives aimed at climate resilience and equitable communities.

Alongside these organizations, there are a number of bioregional learning sites—gathering places where people can come together to learn, exchange ideas, and collaborate on projects related to bioregionalism. These hubs offer educational opportunities and workshops focused on ecological restoration, local food systems, and climate adaptation, providing a space for individuals to connect, learn, and engage with others who share a commitment to improving the quality of life in the region. By fostering these collaborative networks, we can help cultivate a deep, collective responsibility for the health and sustainability of our environment.

As an organization and network development practitioner living in the Lake Washington/Cedar River Watershed, I’ve started mapping organizations and networks active in regenerating the bioregion at various scales. Below is an initial and partial list.
