At Ridge to River we take a comprehensive approach to habitat restoration. The image gallery below will take you on a tour of our process.

Site Assessment

We start with careful observation. Our initial study collects baseline data on existing and historic conditions. This data also helps us monitor the site over time. We  map and analyze the watershed within which we are working to have a comprehensive understanding of influencing factors, land use practices, and the regional setting.

Bioengineering and Erosion Control

Our designs are robust and blend with nature. We use local materials of willow, woody debris, and rock to construct bioengineered structures that both create habitat and prevent erosion. After a few years, our habitat restoration projects blend with nature, appearing to be a healthy ecosystem, undistinguishable from the native environment.

botanical restoration

Cultivation of a successful native plant community is one of the most challenging aspects of habitat restoration. To become established, plants require the right conditions, protection, and resources. Irrigation is especially challenging on many sites.  Ridge to River has established a  variety of species in diverse habitats, including riparian corridors, coastal bluffs, and upland meadows and forests.

Monitoring and Adaptive Management
