The County intends to restore the biodiversity of this former rock quarry site through the removal of exotic weeds and the planting of native vegetation. Much of the wetland area has become overrun with invasive, exotic weeds (Scotch broom - Cystis scoparius, Himalayan blackberry - Rubus discolor, and reed canarygrass - Phalaris arundinacea). These noxious weeds crowd out native grasses, forbs, and wetland plants that provide greater biodiversity and better habitat for fish and wildlife. Each of these invasive exotics has also crowded out woody vegetation that was planted to provide shade and help reduce the wetland water temperatures. Restoration efforts are aimed at improving the quality and diversity of both the aquatic and terrestrial ecosystems.
The following community groups have been involved in restoration activities or planning: Boy Scouts of America Native Plant Society of Oregon Audubon Society Willamette University Chemeketa Community College Friends of Mill Creek Siletz Native American tribe
