Fern Canyon
Fern Canyon is a canyon in the Prairie Creek Redwoods State Park in Humboldt County, California, western United States. The park is managed in cooperation with other nearby redwoods state parks and Redwood National Park. It is named for the ferns growing on the high walls, through which runs Home Creek. Fern Canyon is recognized as a World Heritage Site and an International Biosphere Reserve. History Fern Canyon was donated by the Pacific Lumber Company to the State to add to Prairie Creek State Park. Ferns Fern Canyon has California native ferns covering the sheer walls, giving a primeval habitat quality. Some species include: *''Adiantum aleuticum'' *''Blechnum spicant'' *''Polypodium californicum'' *''Polypodium glycyrrhiza'' *''Polystichum munitum'' Access A hiking trail follows the canyon and creek. The start of Fern Canyon Trail is reached at the bottom of the canyon by hiking a quarter mile north up California Coastal Trail from Fern Canyon Day Use Area, which is ...

Fern Canyon In Redwood National Park, California With Tree Upside Down
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns.

Polypodium Glycyrrhiza
''Polypodium glycyrrhiza'', commonly known as licorice fern, many-footed fern, and sweet root, is a summer deciduous fern native to western North America, where it is found in shaded, damp locations. Spores are located in rounded sori on the undersides of the fronds, and are released in cool weather and high humidity. Description Licorice fern grows single fronds scattered along a thick creeping rhizome; the genus name ''Polypodium'' (many-footed) refers to this characteristic. The fronds are once-divided and triangular in shape, with finely-toothed margins and pointed leaflets. They are usually at least one foot in length, but may grow to be over two feet long, and may be much smaller when growth conditions are less ideal. They also display parallel venation. When sori are present on the leaf underside, they correspond with small bump-like protrusions on the top side of the leaves. The rhizome is creeping and the fronds appear to have random placement, originating at variou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Canyons And Gorges Of California
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examples of mountain-type c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redwood National And State Parks
The Redwood National and State Parks (RNSP) are a complex of one national park and three state parks, cooperatively managed, located in the United States along the coast of northern California. Comprising Redwood National Park (established 1968) and California's State Parks: Del Norte Coast, Jedediah Smith, and Prairie Creek (dating from the 1920s), the combined RNSP contain , and feature old-growth temperate rainforests. Located within Del Norte and Humboldt Counties, the four parks, protect 45 percent of all remaining coast redwood (''Sequoia sempervirens'') old-growth forests, totaling at least . These trees are the tallest, among the oldest, and one of the most massive tree species on Earth. In addition to the redwood forests, the parks preserve other indigenous flora, fauna, grassland prairie, cultural resources, waterways, and of pristine coastline. In 1850, old-growth redwood forest covered more than of the California coast. The northern portion of that area wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roosevelt Elk
The Roosevelt elk (''Cervus canadensis roosevelti)'', also known commonly as the Olympic elk and Roosevelt's wapiti, is the largest of the four surviving subspecies of elk (''Cervus canadensis'') in North America by body mass (although by antler size, both the Boone and Crockett (rifle) and Pope and Young (bow) records have Rocky Mountain elk being larger; none of the top 10 Roosevelt elk would score in the top 20 of Pope and Young's Rocky Mountain elk. In both species, mature bulls weigh from 700 to 1200 lbs. with very rare large bulls weighing more.) Its geographic range includes temperate rainforests of the Pacific Northwest, extending to parts of northern California. It was introduced to Alaska's Afognak, Kodiak, and Raspberry Islands in 1928 and reintroduced to British Columbia's Sunshine Coast from Vancouver Island in 1986. In December 1897, mammalogist C. Hart Merriam named the species after his friend Theodore Roosevelt, then Assistant Secretary of the US Navy. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Red-legged Frog
The northern red-legged frog (''Rana aurora'') is a species of amphibian, whose range is the coastal region stretching from southwest British Columbia to southern Mendocino County in Northern California, and is protected in Oregon and California.''California Wildlife, Volume I: Amphibians and Reptiles'', ed. by D.C. Zeiner et al., published by the California State Department of Fish and Game, 2 May 1988 As a member of the genus ''Rana'', this species is considered a true frog, with characteristic smooth skin and a narrow waist. This frog requires still waters for breeding, and is rarely found at any great distance from its breeding ponds or marshes. Northern red-legged frog adults may attain a length of ; they have dark facial masks and single characteristic light stripes along their jawlines. Stebbins, R.C.

Walking With Dinosaurs
''Walking with Dinosaurs'' is a 1999 six-part nature documentary television miniseries created by Tim Haines and produced by the BBC Science Unit the Discovery Channel and BBC Worldwide, in association with TV Asahi, ProSieben and France 3. Envisioned as the first "Natural History of Dinosaurs", ''Walking with Dinosaurs'' depicts dinosaurs and other Mesozoic animals as living animals in the style of a traditional nature documentary. The series first aired on the BBC in the United Kingdom in 1999 with narration by Kenneth Branagh. The series was subsequently aired in North America on the Discovery Channel in 2000, with Avery Brooks replacing Branagh. ''Walking with Dinosaurs'' recreated extinct species through the combined use of computer-generated imagery and animatronics that were incorporated with live action footage shot at various locations, the techniques being inspired by the film ''Jurassic Park (film), Jurassic Park'' (1993). At a cost of £6.1 million ($9.9 million), ''W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jurassic Park
''Jurassic Park'', later also referred to as ''Jurassic World'', is an American science fiction media franchise centered on a disastrous attempt to create a theme park of cloned dinosaurs. It began in 1990 when Universal Pictures and Amblin Entertainment bought the rights to Michael Crichton's novel ''Jurassic Park'' before it was published. The book was successful, as was Steven Spielberg's 1993 film adaptation. The film received a theatrical 3D re-release in 2013, and was selected in 2018 for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant". A 1995 sequel novel, ''The Lost World'', was followed by a film adaptation in 1997. Subsequent films in the series, including ''Jurassic Park III'' (2001), are not based on the novels. In 2015, a second trilogy of films began with the fourth film in the series, ''Jurassic World.'' The movie was successful, becoming the first film to ...
