Many of the vegetation datasets have been cooperatively produced, but will have stewards responsible for the maintenance and updating of the data. Steward organizations for many of the datasets are listed after the dataset in parentheses, and include the California Dept. of Fish and Wildlife (CDFW), the California Native Plant Society (CNPS), the National Park Service (NPS), the Nature Conservancy (TNC). All of the National Park Service vegetation datasets are also available through NPS.
