Sitka Spruce
''Picea sitchensis'', the Sitka spruce, is a large, coniferous, evergreen tree growing to just over tall, with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world (behind giant sequoia, coast redwood, kauri, and western red cedar), and the third-tallest conifer species (after coast redwood and South Tibetan cypress). The Sitka spruce is one of only five species documented to exceed in height. Its name is derived from the community of Sitka in southeast Alaska, where it is prevalent. Its range hugs the western coast of Canada and the US and continues south into northern California. Description The bark is thin and scaly, flaking off in small, circular plates across. The inner bark is reddish-brown. The crown is broad conic in young trees, becoming cylindric in older trees; old trees may not have branches lower than . The shoots are very pale buff-brown, almost w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hoh Rainforest
Hoh Rainforest is one of the largest temperate rainforests in the U.S., located on the Olympic Peninsula in western Washington (state), Washington state. It encompasses of low elevation forest along the Hoh River, ranging from . The rainforest receives an average of of annual precipitation—among the rainiest places in the United States. The Hoh River valley was formed thousands of years ago by glaciers and is the ancestral home of the Hoh people. Within Olympic National Park, the forest is protected from commercial exploitation. Between the park boundary and the Pacific Ocean, of river, much of the forest has been logged within the last century, although many pockets of forest remain.

Pulvini
A pulvinus (pl. ''pulvini'') may refer to a joint-like thickening at the base of a plant leaf or leaflet that facilitates growth-independent movement. Pulvinus is also a botanical term for the persistent peg-like bases of the leaves in the coniferous genera ''Picea'' and ''Tsuga''. Pulvinar movement is common, for example, in members of the bean family Fabaceae (Leguminosae) and the prayer plant family Marantaceae. Pulvini may be present at the base of the leaf stalk or on its other end (apex), where the leaf is attached, or in a compound leaf at the place where the leaflets are joined to its middle stem. They consist of a core of vascular tissue within a flexible, bulky cylinder of thin-walled parenchyma cells. A pulvinus is also sometimes called a geniculum (meaning a knee-like structure in Latin). Pulvinar movement is caused by changes in turgor pressure leading to a contraction or expansion of the parenchyma tissue. The response is initiated when sucrose is unloaded from ...

Necanicum River
The Necanicum River is a river on the Pacific coast of northwest Oregon in the United States, approximately long. It drains a timber-producing area of the Northern Oregon Coast Range northwest of Portland. It forms the first estuary south of the mouth of the Columbia River along the Oregon Coast, reaching the Pacific Ocean at Seaside in Clatsop County. History ''Necanicum'' is one of several Indian names in northwest Oregon beginning with ''ne'', meaning ''place''. Necanicum is derived from Ne-hay-ne-hum, the name of an Indian village once on the stream. William Clark named it Clatsop River on January 7, 1806, but the name did not stick. The river was also once known as Latty Creek, for William Latty, an early pioneer in the southern part of Seaside. Watershed and course The Necanicum River rises south of Humbug Mountain (not to be confused with the Humbug Mountain in southwestern Oregon), in south central Clatsop County and south of the Saddle Mountain State Natural A ...

He threw them into the water and from them a man and a woman came forth, who beca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diameter At Breast Height
Diameter at breast height, or DBH, is a standard method of expressing the diameter of the trunk or bole of a standing tree. DBH is one of the most common dendrometric measurements. Tree trunks are measured at the height of an adult's breast, which is defined differently in different countries and situations. In many countries, DBH is measured at approximately above ground. Global variation and scientific precision The height can make a substantial difference to the measured diameter. In the United States, DBH is typically measured at above ground. In some countries, such as Australia, New Zealand, Burma, India, Malaysia, and South Africa, breast height diameter has historically been measured at a height of , but because of much active research into allometrics that are being applied to trees and forests, the convention of is more appropriate. Ornamental trees are usually measured at 1.5 metres above ground. Some authors have argued that the term DBH should be abolish ...

Redwood National And State Parks
The Redwood National and State Parks (RNSP) are a complex of one United States national park and three California state parks located along the coast of northern California. The combined RNSP contain Redwood National Park, Del Norte Coast Redwoods State Park, Jedediah Smith Redwoods State Park, and Prairie Creek Redwoods State Park. The parks' 139,000 acres (560 km2) preserve 45 percent of all remaining old-growth coast redwood forests. Located in Del Norte and Humboldt counties, the four parks protect the endangered coast redwood (''Sequoia sempervirens'')—the tallest, among the oldest, and one of the most massive tree species on Earth—which thrives in the humid temperate rainforest. The park region is highly seismically active and prone to tsunamis. The parks preserve 37 miles (60 km) of pristine coastline, indigenous flora, fauna, grassland prairie, cultural resources, waterways, as well as threatened animal species, such as the Chinook salmon, northern spotted owl, ...

Seed
In botany, a seed is a plant structure containing an embryo and stored nutrients in a protective coat called a ''testa''. More generally, the term "seed" means anything that can be Sowing, sown, which may include seed and husk or tuber. Seeds are the product of the ripened ovule, after the embryo sac is fertilization, fertilized by Pollen, sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote and grows within the mother plant to a certain size before growth is halted. The formation of the seed is the defining part of the process of reproduction in seed plants (spermatophytes). Other plants such as ferns, mosses and marchantiophyta, liverworts, do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological Ecological niche, niches on land, from forests to grasslands both in hot and cold climates. In the flowering plants, the ovary ripens into a fruit which contains the seed and serves to disseminate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conifer Cone
A conifer cone, or in formal botanical usage a strobilus, : strobili, is a seed-bearing organ on gymnosperm plants, especially in conifers and cycads. They are usually woody and variously conic, cylindrical, ovoid, to globular, and have scales and bracts arranged around a central axis, but can be fleshy and berry-like. The cone of Pinophyta (conifer clade) contains the reproductive structures. The woody cone is the female cone, which produces seeds. The male cone, which produces pollen, is usually ephemeral and much less conspicuous even at full maturity. The name "cone" derives from Greek ''konos'' (pine cone), which also gave name to the geometric cone. The individual plates of a cone are known as ''scales''. In conifers where the cone develops over more than one year (such as pines), the first year's growth of a seed scale on the cone, showing up as a protuberance at the end of the two-year-old scale, is called an ''umbo'', while the second year's growth is called th ...
