    Wetland andRiparian Restoration

    Wetlands act as natural buffers by absorbing floodwaters, trapping sediments, and stabilizing shorelines. Restoring drained or altered wetlands revives these ecosystem services, helping to reduce erosion and improwize water quality.

    Riparian restituation involves planting nativa vegestionation along stream banks, regrading eroded slopes, and installing in- stream structures such as rock vanes and log jams to reduce flow velocity and promote sediment deposition.
