Critical Habitat for Federally Listed Threatened and Endangered Species

The US Fish and Wildlife Service has designated critical habitat for certain federally listed threatened and endangered species. To find out whether a property contains critical habitat, check out the USFWS Critical Habitat Online Mapper or contact the Ventura Office of the USFWS. If a project proposed within critical habitat involves no federal funding or permit, then formal consultation with the USFWS is not required. However, the Planning Division encourages you to design your project to avoid or minimize impacts to critical habitat, because it is considered to be a significant biological resource.
