We restore degraded areas within and adjacent to watercourses to reproduce more natural conditions which benefit a variety of species. For example, we have helped create instream habitat structures, reduced invasive exotic plants, and replanted native riparian vegetation in several areas. |

As coastal water bodies where freshwater from streams and rivers mix with salty ocean water, estuaries are among the most productive and valuable ecosystems on earth. They perform valuables services such as absorbing flood waters and filtering sediments and pollutants. Additionally, they create a relatively large amount of organic matter for their size and support unique, diverse, abundant communities of creatures. Their protected and productive nature lead them to be called “nature’s nurseries.” Today, more than 90 percent of California’s coastal wetlands have been lost to diking, draining, and filling. We endeavor to improve the structure and function of degraded estuaries in order to restore them to more healthy and natural conditions. For example, we are installing fish-friendly tidegates in Salmon Creek Estuary to increase circulation and sediment transport while reducing fish barriers and stranding. |

With the north coast’s generally steep and erosive geology, one of the most important elements needed for restoration of watershed ecosystems and salmonid habitat is the reduction of anthropogenic erosion into stream systems. Roads are now widely recognized as one of the most significant, and most easily controlled, sources of sediment production and delivery to stream channels. We perform road assessments and decommissioning to restore the integrity of associated hillslopes, channels, and flood plains and their related hydrologic, geomorphic, and ecological processes and properties.

We help restore access to upstream habitat for salmonids and other species by eliminating high priority barriers and replacing them with fish friendly structures. For example, we have removed culverts that create velocity and height barriers to salmonids and replaced them with bridges and gradual roughened channels which simulate more natural and passable stream conditions. |
