California protected areas

According to the California Protected Areas Database (CPAD), 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.^[1] 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 (5,300 km²), with over 280 miles (450 km) of coastline, 625 miles (1,006 km) of lake and river frontage, nearly 18,000 campsites, and 3,000 miles (5,000 km) 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. The Cosumnes River Preserve is an extreme example, owned and managed by a handful of public agencies and private landowners, including the Bureau of Land Management, the County of Sacramento and The Nature Conservancy. Despite the difficulties, the CPAD gives the total area of protected land at 49,000,000 acres (200,000 km²), or 46.7% of the state (not including easements); a considerable amount for the most populous state in the country.

National Park System

The U.S. National Park System controls a large and diverse group of California parks, monuments, recreation areas and other units which in total exceed 6,240,000 acres (25,300 km²).^[2] The best known is Yosemite National Park, noted for several iconic natural features including Yosemite Falls, El Capitan and Half Dome, which is displayed on the reverse side of the California state quarter. Other prominent parks are the Kings Canyon-Sequoia National Park complex, Redwood National Park, Channel Islands National Park, Joshua Tree National Park and the largest, Death Valley National Park. The NPS also administers the Manzanar National Historic Site in Inyo County.

National Landscape Conservation System

The Bureau of Land Management’s National Landscape Conservation System (NLCS) includes over 850 federally recognized areas and in California, manages 15,500,000 acres (63,000 km²) of public lands, nearly 15% of the state's land area.^[3] The National Landscape Conservation System is composed of several types of units: national monuments (distinct from the same-named units within the National Park System), national conservation areas, forest reserves, outstanding natural areas, national scenic and historic trails, wilderness, wilderness study areas, and others.

The National Marine Sanctuary System is managed by the Office of Marine Sanctuaries, of the National Oceanic and Atmospheric Administration.

California has four of the thirteen U.S. National Marine Sanctuaries:

• Channel Islands National Marine Sanctuary
• Cordell Bank National Marine Sanctuary
• Gulf of the Farallones National Marine Sanctuary
• Monterey Bay National Marine Sanctuary- one of the largest in the world at 5,300 square miles (14,000 km²).^[5]

National Wildlife Refuges

National Wildlife Refuge (NWR) is a designation for certain protected areas of the United States managed by the United States Fish and Wildlife Service. The National Wildlife Refuge System is an extensive system of public lands and waters set aside to conserve America's fish, wildlife and plants. Many of the state's refuges are important stops and destinations for millions of migrating birds along the Pacific Flyway corridor. One, the Butte Sink Wildlife Management Area, has the highest density of waterfowl in the world.^[6] There are 38 units in the refuge system in California, including both wildlife refuges and wildlife management areas, divided into 9 different regional areas. Combined the areas equal about 440,000 acres (1,800 km²).

Wild and Scenic rivers

Rivers designated as Wild and Scenic are administered by one of four federal land management agencies: The Bureau of Land Management, The National Park Service, The U.S. Fish and Wildlife Service or The U.S. Forest Service.[7] There are 22 rivers in California with portions designated as Wild and Scenic, with 23 designations in all (the American River has two separate designations, one for the North Fork, and one for the Lower section).[8]

National Wilderness Preservation System

Emerald Lake in the Trinity Alps Wilderness

There are 149 wilderness areas in California totaling just over 15,000,000 acres (61,000 km²).^[9] The largest is Death Valley Wilderness at 3,055,413 acres (12,364.82 km²), the largest federally designated wilderness in the continental United States, and the smallest is the Rocks and Islands Wilderness at 5 acres (20,000 m²). The wilderness areas are managed by the US Forest Service, Bureau of Land Management, US Fish and Wildlife Service and the National Park Service. It should be noted that rarely, if ever, are designated wilderness areas stand alone protected areas, and thus their areas are, in all likelihood, already accounted for in the various agencies' inventories.

National Forests

California has 17 U.S. National Forests, one special management unit (Lake Tahoe) and parts of 3 other National Forests. Total combined area of the forests is 20,061,888 acres (81,187.58 km^2) and covers over 19% of the state. The largest forest entirely within the state is Shasta-Trinity National Forest, at 2,209,832 acres (8,942.87 km^2), the smallest is Cleveland National Forest at 460,000 acres (1,900 km^2). The Lake Tahoe Basin Management Unit is not precisely a national forest in the conventional sense. Instead the Forest Service manages the land with particular attention paid to Lake Tahoe and its relationship with the forests surrounding it, with emphasis on erosion control management and watershed restoration, among other more conventional forest management activities. It is the smallest of the Forest Service units in California, with 191,000 acres (770 km^2) in its jurisdiction split between California and Nevada.

The Inyo National Forest contains Mount Whitney, the highest point in California.

State parks

Sunset at Bolsa Chica State Beach

The California Department of Parks and Recreation maintains over 270 protected areas, which include almost one-third of California's scenic coastline, including coastal wetlands, estuaries, beaches, and dune systems. The state parks system covers 1.3 million acres (5,300 km²), with over 280 miles (450 km) of coastline, 625 miles (1,006 km) of lake and river frontage, nearly 18,000 campsites; and 3,000 miles (5,000 km) of hiking, biking, and equestrian trails.^[10] The largest is Anza-Borrego State Park at 600,000 acres (2,400 km²), making it one of the largest state parks in the country. The smallest, Watts Towers, owned by the State Park system but managed by the Los Angeles Cultural Affairs Department,^[11] is a mere 0.1-acre (400 m²).

State wilderness areas

  section of Big Basin State Park

Additionally, 386,000 acres (1,560 km²) of Anza-Borrego State Park have been designated as wilderness.^[12]

Department of Fish and Game Protected Areas

Rain-soaked wetlands at the Yolo Bypass Wildlife Area

The California Department of Fish and Game (DFG), through its seven regional divisions,^[13] manages more than 700 protected areas statewide, totaling 1,119,360 acres (4,529.9 km²).^[14] They are broadly categorized as:

• 110 wildlife areas,^[15] designed to give the public easier access to wildlife while preserving habitats.
• 123 ecological reserves,^[16] which protect rare terrestrial species and habitats.
• 11 marine reserves, which do the same for sea-dwelling species and habitats.

Municipal parks

Griffith Park in the city of Los Angeles

Most cities and counties in California, as in elsewhere, own and operate open spaces of various types, the most recognizable being the city and county park. By far the largest inventory of protected land held by a municipal agency belongs to the Los Angeles Department of Water and Power, with just over 400,000 acres (1,600 km²) in its jurisdiction.^[17] The largest city park in the state is Mission Trails Regional Park in San Diego at 5,800 acres (23 km²), although there are several county and regional parks that are larger. Total land owned by municipal agencies is roughly 1,500,000 acres (6,100 km²) acres.

Privately owned preserves

Santa Cruz Island

In addition to the many public lands are about 550,000 acres (2,200 km²)of privately owned preserves. The Wildlands Conservancy is the largest owner of protected lands with 145,371 acres (588.30 km²). The Nature Conservancy has been involved in over 100 projects in the state since 1958.^[18] Many are eventually transferred to public agencies, but the Conservancy still owns and maintains several substantial preserves, including the Gray Davis/Dye Creek Preserve, Vina Plains Preserve, McCloud River Preserve, Cosumnes River Preserve, Santa Cruz Island, Irvine Ranch Wildlands and the Santa Rosa Plateau Ecological Reserve. The largest private preserve is the 93,000 acres (380 km²) Wind Wolves Preserve owned by the aforementioned Wildlands Conservancy.^[19] In total, there are many dozens of land trust and conservation organizations active in California, with thousands of acres preserved on public and private lands through their efforts.^[20] A few that operate entirely or substantially in the state are the Peninsula Open Space Trust, the Northern Sierra Partnership, the Sempervirens Fund, the Sacramento Valley Conservancy and the Wilderness Land Trust.
