The Coastal redwood is the tallest tree species on Earth.
The 'Redwood National and State Parks' (RNSP) are located in the
United States, along the
Pacific Ocean coast of northern
California. With an area of 112,512 acres (45,500 ha), the parks protect 45% of the remaining groves of
coastal redwood (''Sequoia sempervirens'')
trees, the tallest and one of the most massive tree species on Earth. In addition to the redwood forests, the parks preserve grassland
prairie, cultural resources, and 37 miles (60 km) of pristine coastline.
In 1850,
old growth redwood forest covered 2 million acres (810,000 ha) of the north California coast, an area which had been inhabited by
Native Americans for 3,000 years, when a minor
gold rush brought miners and
loggers who began cutting down the trees. The efforts of the
Save-the-Redwoods League, founded in 1918, to preserve three large redwood groves eventually resulted in the establishment of
Prairie Creek,
Del Norte Coast, and
Jedediah Smith Redwoods State Parks.
Redwood National Park was created in 1968, by which time nearly 90% of the original redwood trees had been logged. The
National Park Service and the
California Department of Parks and Recreation administratively combined Redwood National Park with the three state parks in 1994, a degree of collaboration between the National Park Service and a state park system which is unique in the U.S.
The ecosystem of the RNSP preserves a number of
threatened animal species such as the
brown pelican,
tidewater goby,
bald eagle,
chinook salmon,
northern-spotted owl, and
Steller's sea lion.
[1] In recognition of the rare ecosystem and cultural history found in the parks, the
United Nations designated them a
World Heritage Site on
September 5,
1980,
[2] and an
International Biosphere Reserve on
June 30,
1983.
History
As early as 3,000 years ago,
Native Americans lived in the park area. Such groups as the
Yurok,
Tolowa,
Shasta,
Karok,
Chilula, and
Wiyot all have historical ties to the region. An 1852 census determined that the Yurok were the most numerous, with 55 villages and an estimated population of 2,500.
[3] They used the abundant redwood, which with its linear
grain was easily split into planks, as a building material for boats, houses, and small villages.
[4] For buildings, the planks would be erected side by side in a narrow trench, with the upper portions bound with
leather strapping and held by notches cut into the supporting roof beams. Redwood boards were used to form a shallow sloping roof.
[5]
Spanish,
British,
Russian, and American explorers visited the coast near the present park as early as the mid 16th century, to trade with local people for
seal pelts. Until the arrival of
Jedediah Smith, in 1828, no white explorer is known to have thoroughly investigated the inland region. The discovery of gold along Trinity Creek in 1850 brought thousands of miners into the area, which led to conflicts; the native peoples were forcibly removed and in some cases massacred.
[6][7] By 1895, only one third of the Yurok in one group of villages remained; and, by 1919, virtually all members of the Chilula tribe had either died or been assimilated into other tribes.
[8] The miners
logged redwoods for building; and, when this minor
gold rush ended, some of them became loggers, cutting down as many trees as they could sell. In 1850, 2 million
acres (810,000
ha) of the northwest California coast was old-growth redwood forest; but, by 1910, so many redwoods had been cut down that
conservationists and concerned citizens began seeking ways to preserve the remaining trees.
[9] In 1911,
U.S. Representative John E. Raker, of California, became the first politician to introduce legislation for the creation of a national park. However, no further action was taken by Congress at this time.
The completion of
U.S. Route 101 brought conservationists
John C. Merriam,
Madison Grant, and
Henry Fairfield Osborn to the region. Disappointed to find that there were no public lands set aside to preserve the redwoods, they founded the
Save-the-Redwoods League in 1918. Using matching funds provided by the state of California, the Save-the-Redwoods League managed to save three large redwood groves by the early 1920s. When California created a state park system, in 1927, these three groves became the Prairie Creek Redwoods, Del Norte Coast Redwoods, and Jedediah Smith Redwoods State Parks. Because of the high demand for lumber during
World War II and the construction boom of the 1950s, the creation of a national park was delayed. Efforts by the Save-the-Redwoods League, the
Sierra Club, and the
National Geographic Society to create a national park began in the early 1960s. After intense lobbying of
Congress, the bill creating Redwood National Park was signed by
President Lyndon Johnson on
2 October 1968. The Save-the-Redwoods League and other entities purchased over 100,000 acres (40,000 ha), which were added to existing state parks. In 1978, 48,000 acres (19,000 ha) were added to Redwood National Park in a major expansion. However, only a fifth of that land was old-growth forest, the rest having been logged. This expansion protected the watershed along
Redwood Creek from being adversely affected by logging operations outside the park. The federal and state parks were administratively combined in 1994.
[10]
The
United Nations designated Redwood National and State Parks a
World Heritage Site on
5 September 1980. The evaluation committee noted 50 prehistoric
archaeological sites, spanning 4,500 years. It also cited ongoing research in the park by
Humboldt State University researchers, among others.
[11] The park is part of a much larger region designated the ''California Coast Ranges''
International Biosphere Reserve on
June 30,
1983.
[12] The California Coast Ranges biosphere is overseen by the
University of California Natural Reserve System.
Park management

Map of Redwood National and State Parks
The RNSP are managed jointly by the
National Park Service, a federal agency within the
U.S. Department of the Interior, and the
California Department of Parks and Recreation, with an annual budget of $7,380,000 (2004).
[13] The two agencies work cooperatively to protect the redwoods, the pristine Pacific Ocean coastline, the cultural resources, and the unique natural habitat. The land that was added to the parks in 1978 had previously been logged, and efforts to restore these areas have been ongoing for decades, with old logging roads being removed and the land allowed to return to its original state. Lack of funding has precluded major improvements, however, and timber companies have replanted much of the logged area with non-native tree species. Coastline areas, including dunes and coastal prairie, have been invaded by exotic species, partly due to the suppression of
forest fires until the 1980s. A fire management plan now allows
controlled burning as one method to return the parkland to its original state. Since the redwoods were logged on the basis of accessibility, with inaccessible areas being cut last, large old growth forest sections were isolated from one another, sometimes by many miles. In these cases it will be decades more before mature forest can return, regardless of the amount of money used to rehabilitate the ecosystem.
[14]
The park has transformed a few logging roads into scenic public drives. These do not meet current safety standards, but funding to improve them is not available at present. Park structures such as visitor centers and employee housing also need updating to meet increasing demands. The park employees perform air and water quality surveys, monitor endangered and
threatened species, and work closely with the
California Coastal National Monument, which is managed by the
U.S. Bureau of Land Management.
[15] The park headquarters is in
Crescent City, California.
Natural resources
Flora

Redwood grove shrouded in fog.
It is estimated that old growth redwood forest once covered 2 million acres (810,000 ha) of coastal northern California. Today, only 4%, or 85,000 acres (34,000 ha), remain, with 45% of that total being managed by the park.
[16] The native range of coast redwood is from the northern California coast north to the southern
Oregon Coast. The tree is closely related to the
Giant Sequoia of central California, and more distantly to the
Dawn Redwood which is indigenous to the
Sichuan-
Hubei region of
China. Coast redwoods are the tallest trees on Earth; in September, 2006, the tallest tree in the park is
hyperion at 378.1ft, two more named
helios and
icarus are 376.3 ft and 371.2 ft respectively.
[17] Before September 2006, the tallest living specimen known was the
Stratosphere Giant, outside the park in
Humboldt Redwoods State Park, which was 370 feet (113 m) in 2004. For many years, one specimen simply named "Tall Tree" in Prairie Creek Redwoods State Park and within the RNSP was measured at 367.8 feet (112.11 m), but the top 10 feet (3 m) of the tree was reported to have died in the 1990s.
[18] One tree that fell in 1991 was reported to be 372.04 feet (113.4 m). Only the Giant Sequoia has more mass. The largest redwood by volume is the 1,365.5 yd³ (1,044 m³) "Del Norte Giant", located in Del Norte Redwoods State Park. Coast redwoods live an average of 600 years and a few are documented to be 2,000 years old, making them some of the longest-living organisms on earth. They are highly resistant to disease, due to a thick protective bark and high
tannin content. Redwoods prefer sheltered slopes, slightly inland and near water sources such as rivers and streams.
Redwood trees develop enormous limbs that accumulate deep organic soils and can support tree-sized trunks growing on them. This typically occurs above 150 feet. Scientists have recently discovered that plants that normally grow on the forest floor also grow in these soils, well above ground. The soil mats provide homes to
invertebrates,
mollusks,
earthworms, and
salamanders. During
drought seasons, some treetops die back, but the trees do not die outright. Instead, redwoods have developed mechanisms to regrow new trunks from other limbs. These secondary trunks, called ''reiterations'', also develop root systems in the accumulated soils at their bases. This helps transport water to the highest reaches of the trees. Coastal fog also provides up to one-third of their annual water needs.
[19]
Another large tree commonly found in the forest is the
Douglas-fir, which has been measured at heights of over 300 feet (90 m).
Sitka Spruce are plentiful along the coast and are better adapted to salty air than other species. The
evergreen hardwood
tanoak produces a nut similar to the
acorns produced by the related genus Quercus (
oak). Both tanoaks and oaks are members of the
beech family. Trees such as the
madrone,
big-leaf maple,
California laurel, and
red alder are also widespread throughout the parks.
Huckleberry,
blackberry, and
salmonberry are part of the forest
understory and provide food for many animal species. The
California rhododendron and
azalea are flowering shrubs common in the park, especially in old growth forest.
[20] Plants such as the
sword fern are prolific, especially near ample water sources. In Prairie Creek Redwoods State Park,
Fern Canyon is a well-known ravine 30 to 50 feet (10–15 m) deep, with walls completely covered in ferns.
Fauna
The ecosystems of RNSP preserve a number of rare animal species. Numerous ecosystems exist, with seacoast, river, prairie, and densely forested zones all within the park. The
brown pelican and
tidewater goby are federally listed
endangered species that live near the Pacific coastline. The
bald eagle, which usually nests near a water source, is listed as a
threatened species, a designation which includes
vulnerable,
endangered, and
critically endangered species, by the
U.S. Fish and Wildlife Service; the state of California lists it as endangered. The
chinook salmon,
northern-spotted owl, and the
Steller's sea lion are a few of the other animal species that are threatened.
[1]
Over 40 species of mammals have been documented, including the
black bear,
mountain lion,
bobcat,
beaver,
river otter,
black-tailed deer,
elk, and
coyote. Along the coastline,
California sea lions, and
harbor seals live near the shore and on seastacks, rocky outcroppings forming small islands just off the coast.
Dolphins and
Pacific gray whales are occasionally seen offshore. Elk are the most readily observed of the large mammals in the park. Many smaller mammals live in the high forest canopy. Different species of
bats, such as the
big brown bat and other smaller mammals including the
red squirrel and
northern flying squirrel, spend most of their lives well above the forest floor.
[22]
Brown pelicans and
double-crested cormorants are mainly found on cliffs along the coast and on seastacks, while
sandpipers and
gulls inhabit the seacoast and inland areas. Inland, freshwater dependent birds such as the
common merganser,
osprey,
red-shouldered hawk,
great blue heron, and
Stellar's jay are a few of the species that have been documented.
Reptiles and
amphibians can also be found in the parks, with the
northwestern ringneck snake,
red-legged frog,
pacific giant salamander, and the
rough-skinned newt most commonly seen.
[23]
Geology
The northern coastal region of California, which includes RNSP and the adjacent offshore area, is the most
seismically active in the U.S.
[24] Frequent minor
earthquakes in the park and offshore under the Pacific Ocean have resulted in shifting river channels,
landslides, and
erosion of seaside cliffs. The
North American,
Pacific, and
Gorda Plates are
tectonic plates that all meet at the
Mendocino triple junction, only 100 miles (160 km) southwest of the parks. During the 1990s, more than nine
magnitude 6.0 earthquakes occurred along this
fault zone, and there is always potential for a major earthquake.
[25] The park ensures that visitors are aware of the potential for a major earthquake through the use of pamphlets and information posted throughout the parks. The threat of a
tsunami is of particular concern, and visitors to the seacoast are told to seek higher ground immediately after any significant earthquake.
[26]

Coastline area
Both coastline and the
Coast Ranges can be found within park boundaries. The majority of the rocks in the parks are part of the
Franciscan Assemblage, uplifted from the ocean floor millions of years ago. These
sedimentary rocks are primarily
sandstones,
siltstones, and
shales, with lesser amounts of
metamorphic rocks such as
chert and
greenstone. For the most part, these rocks are easily eroded, and can be viewed along the seacoast and where rivers and streams have cut small gorges. Formed during the
cretaceous age, they are highly deformed from uplift and folding processes. In some areas, river systems have created
fluvial deposits of sandstones,
mudstones, and
conglomerates, which are transported into the park from upstream.
Redwood Creek follows the Grogan Fault; along the west bank of the creek,
schist and other metamorphic rocks can be found, while sedimentary rocks of the Franciscan Assemblage are located on the east bank.
[27]
Climate
Weather in RNSP is greatly influenced by the Pacific Ocean. Coastal temperatures generally range between 40 and 60 degrees Fahrenheit (4—15°C) all year round, while further from the coast summers are hotter and drier, and winters are colder. Redwoods mostly grow a mile or two (1.5—3 km) from the coast, but never more than 50 miles (80 km) from it. In this zone they have an abundance of moisture from heavy winter rains and persistent fog for much of the summer. Most of the 100 inches (250 cm) of annual precipitation falls during the winter, but snow is uncommon even on peaks above 1,500 feet (450 m). The higher humidity of the winters and foggy conditions in the summer are essential for redwood forest survival; further inland the life-giving summer fog is less common.
[28]
Fire management

Fog is persistent during the summer, as seen here, and the majority of fires are during the fall.
Wildfires are a natural part of most terrestrial ecosystems. In many ways nature has adapted to fire, and the absence of fire can often be disadvantageous.
[29] Wildfire eliminates dead and decayed plant and tree matter, enriching the soil and ensuring that healthier trees have less competition for limited nutrients. Until the arrival of European settlers, wildfires periodically burned sections of the redwood forest. From 1850, however, fires were combatted by logging interests, who were concerned both with a loss of their commodity and with the threat to personal safety that fire presented. Miners and loggers who came to the region set out to ensure that all fires would be suppressed as quickly as possible, and the net result was a buildup of dead and decaying
flora. During the 1970s, research indicated that there was an immediate need to allow natural fires to burn, so long as personal safety and structures were not compromised. Later, man-made fires were deliberately set to burn off plant matter and reduce the risk of a major
firestorm. In the RNSP, a fire management plan monitors all fires, weather patterns and the fuel load (dead and decaying plant material). This fuel load removed from areas near structures and where fire poses high risk to the public, and controlled burns are used elsewhere.
[30] The
National Interagency Fire Center provides additional firefighters and equipment in the event of a large fire.
Fire is also used to protect prairie grasslands from invasion by
exotic species and to keep out forest encroachment, ensuring sufficient rangeland for elk and deer. The oak forest regions also benefit from controlled burns, as Douglas fir would otherwise eventually take over and decrease
biodiversity. The use of fire in old growth redwood zones reduces dead and decaying material, and lessens the mortality of larger redwoods by eliminating competing vegetation.
[31]
Recreation
Other than the DeMartin Redwood Youth Hostel, a low-amenities shared lodging facility, there are no
hotels or
motels within the parks. Nearby towns such as
Eureka and Crescent City have accommodation facilities. The park is 340 miles (550 km) north of
San Francisco, California, and 330 miles (530 km) south of
Portland, Oregon, and
U.S. Route 101 passes through it from north to south. The
Smith River National Recreation Area, part of the
Six Rivers National Forest, is adjacent to the north end of RNSP.
While the state parks have front country campsites that can be driven to, the federal sections of the park do not, and hiking is the only way of reaching back country campsites. These are at Mill Creek campground in Del Norte Coast Redwoods State Park and Jedediah Smith campground in Jedediah Smith Redwoods State Park, which together have 251 campsites, the Elk Prairie campground in Prairie Creek Redwoods State Park which has 75, and the Gold Bluffs Beach campground which has 25 campsites. Other nearby state parks have additional front country camping.
[32] Back country camping is by permit only and is only allowed in designated sites, except on gravel bars along
Redwood Creek.
The back country is highly regulated to prevent overuse and to permit as many groups as possible to explore the forest. Camping in the back country is therefore limited to five consecutive nights, and 15 nights in any one year. Proper food storage to minimize encounters with bears is strongly enforced,
[33] and hikers and backpackers are required to take out any trash they generate.
Almost 200 miles (320 km) of hiking trails exist in the parks, but during the rainy season some temporary footbridges are removed, as they would be destroyed by high streams. Throughout the year, trails are often wet and hikers need to be well prepared for rainy weather and consult information centers for updates on trail conditions.
Horseback riding and
mountain biking are popular but are only allowed on certain trails.
Kayaking is popular along the seacoast and in the various rivers and streams. Kayakers and canoeists frequently travel the
Smith River, which is the longest un
dammed river remaining in California.
Fishing for
salmon and
steelhead, (a highly prized
rainbow trout over 16 inches (40 cm) long), is best in the Smith and
Klamath rivers. A California sport fishing license is required to fish any of the rivers and streams. Hunting is not permitted anywhere in the parks, but is allowed in nearby
National Forests.
The park has two visitor centers and three additional information points. At the visitor centers, guided nature walks and general information is available. Each campground offers campfire talks during the summer months as well as guided tours. The parks have many
picnic areas, which are all easily accessed by vehicle.
In films
The park has served as location shots for numerous films. The
Endor scenes for the
Star Wars movie ''
Return of the Jedi'' (Episode 6) were filmed in the Tall Trees Redwood Grove in the northern part of Humboldt County. Scenes for '' as well as the movie ''
Outbreak'', were filmed at the nearby
Prairie Creek Redwoods State Park and at Patrick's Point State Park.
