The Creation of Redwood National and State Parks
Redwood National and State Parks—an unusual name for an unusual park. It’s a unique federal-state cooperation agreement between Prairie Creek Redwoods State Park (founded in 1923), Del Norte Coast Redwoods State Park (founded in 1925), Jedediah Smith Redwoods State Park (founded in 1929), and Redwood National Park (founded in 1968), which controls large sections of forest adjacent to the state parks.
In 1994 the four parks signed the historic cooperation agreement that allows them to share resources and tasks, bringing increased efficiency and a better experience for park visitors.
Redwood National and State Parks: United Nations World Heritage Site
In 1980 Redwood National Park was designated a United Nations World Heritage Site, and the designation was extended to all of Redwood National and State Parks after the cooperation agreement of 1994. A ceremony marking the honor occurred near the trailhead of the Lost Man Creek trail in 1992.
Coast Redwood Facts
The coast redwood, with its red bark, massive girth, and soaring height, is one of the world’s most magnificent trees.
Scientific Name: Sequoia sempervirens
Sequoia sempervirens is the only living species of the genus Sequoia.
There are two related species. Sequoiadendron giganteum is the “giant sequoia” that grows in certain groves of California’s Sierra Nevada mountain range. Metasequoia glyptostroboides, also known as the “dawn redwood,” grows in Hubei Province, China.
What Does “sempervirens” Mean?
Sempervirens is a Latin term that means “ever living,” “always alive,” or more generally “ever green.”
What Is the Current Habitat/Range of the Coast Redwood?
Coast redwoods inhabit a strip of land near (but not on) the coast and stretching a bit inland from southern Oregon (just across the California border along the Chetco River near Brookings) down to Monterey County. The inland distance from the coast is determined by several factors, the most important being overall moisture availability, including the presence of summer fog.
These trees’ geographic range is determined primarily by moisture availability. Precipitation amounts of up to one hundred inches per year are common in Del Norte and Humboldt Counties, which contain Redwood National and State Parks. The availability of summer fog is key to redwood survival: the trees absorb moisture through both leaves and bark during the long months of summer drought.
How Long Do Coast Redwoods Live?
Up to 2000 years!
And as a species, they have been in existence for 200+ million years. Fossils have been found with imprints of twigs and leaves.
How Big Can a Coast Redwood Get?
The Hyperion Tree in Redwood National Park is the current record holder at 380 feet high.
Heights over 200 feet are quite common. The biggest trees grow on and near flats beside streams, where soil conditions are optimal, with size diminishing on slopes and ridges.
Diameters can be as much as 30 feet!
How Do Coast Redwoods Reproduce/Grow?
They commonly grow from seeds and can grow rapidly, up to sixty feet or more, in their first couple of decades of life. They can also reproduce asexually, including from stumps, burls (thick, woody knobs) on trunks, and from fallen trees.
Want to Explore This Area?
Then I suggest getting my book Hike the Parks: Redwood National & State Parks from your favorite bookseller or your library. It covers 38 trails in and near the parks, plus includes information on campgrounds, whale watching, tide pools, beach walks, and much more, nearly all of it accessible from Highway 101 in Humboldt County and Del Norte County.
