Our Projects

WRA Landscape Restoration is working with The California Invasive Plant Council (Cal-IPC) on the Invasive Spartina Project (ISP) to treat the invasive hybrid plant Spartina (alterniflora x foliosa). Removal is executed through careful application of an herbicide via backpack sprayers at various tidal wetland sites within San Mateo County, California.

To access these sites, the WRA Landscape Restoration team traveled via airboat to remote locations, consciously working around tidal patterns to allow for effective and precise application. The ISP, led by the California Coastal Conservancy, is a coordinated regional effort to preserve coastal natural resources by eliminating the introduced species of cordgrass (Spartina alterniflora), which has hybridized with the native cordgrass (Spartina foliosa). These highly aggressive invaders are a major threat to natural habitat and species in tidal marshes, mudflats, and creeks.
