This layer contains polygon data for the perennial pepperweed (Lepidium latifolium) database. This database represents the areas surveyed throughout the San Francisco Bay, San Pablo Bay and Suisun Bay in California between July, 2004 and June, 2007. Perennial pepperweed is a non-native invasive plant that is currently invading wetland, riparian and cultivated areas throughout California. The area surveyed was identified using aerial images. This data layer is to be used in association with the shapefile, "Perennial Pepperweed Patches - San Francisco Estuary [ds295]" which shows the patches of Lepidium latifolium mapped within the areas surveyed.
