context_page_description: According to the California Protected Areas Database, in the state of California, United States, there are over 14,000 inventoried protected areas administered by public agencies and non-profits. In addition, there are private conservation areas and other easements. They include almost one-third of California's scenic coastline, including coastal wetlands, estuaries, beaches, and dune systems. The California State Parks system alone has 270 units and covers 1.3 million acres, with over 280 miles of coastline, 625 miles of lake and river frontage, nearly 18,000 campsites, and 3,000 miles of hiking, biking, and equestrian trails.
  Obtaining an accurate total of all protected land in California and elsewhere is a complex task. Many parcels have inholdings, private lands within the protected areas, which may or may not be accounted for when calculating total area. Also, occasionally one parcel of land is included in two or more inventories. Over 90% of Yosemite National Park for example, is listed both as wilderness by the National Wilderness Preservation System, and as national park land by the National Park Service.
