This polygon shapefile depicts cultivated lands in the nine county San Francisco Bay Area Region, California. This data was derived from the California Department of Conservation Farmland Mapping and Monitoring Program (FMMP) data. FMMP defines Cultivated Land as arable land that is worked by plowing, sowing and raising of crops. The county data was merged into one dataset. The categories that the Conservation Lands Network (CLN) Project considered Cultivated Agriculture were pulled out and compiled for this dataset. Attributes are as follows: Prime Farmland (P), Farmland of Statewide Importance (S) and Unique Farmland (U). The Cultivated Agriculture is an important layer in the development of the CLN. These areas became part of the "Converted" lands and were extracted out of the final CLN. This dataset was developed/compiled for use in the San Francisco Bay Area Upland Habitat Goals Project, a Project used to identify a Conservation Lands Network (CLN) for biodiversity preservation to inform conservation investments and lasting cooperative conservation partnerships. The Conservation Lands Network GIS Database is the primary output of the Project. The data depicts the spatially explicit CLN that is recommended for the nine county San Francisco Bay Area Region, California.
