Perennial pepperweed, Lepidium latifolium, is a highly invasive perennial herb that can thrive in a wide range of habitats including riparian areas, wetlands, marshes, and floodplains. Once established this plant creates large monospecific stands that displace native plants and animals and can alter soil composition by concentrating salts at the surface.
In the Cosumnes River Preserve, Lepidium has emerged as the invasive plant of most concern in its restoration projects. The Cosumnes River Preserve (CRP) serves as a model of habitat conservation and floodplain restoration in the Central Valley.
