Pinus Ponderosa Var. Willamettensis
The Willamette Valley ponderosa pine is a population of the ponderosa pine (''Pinus ponderosa'') native to the Willamette Valley in Oregon. It is adapted for Western Oregon's wet winter and dry summer. History The Willamette Valley ponderosa variant only grows on the valley floor, unlike the Douglas-fir, which grows on hillsides, and the wood is softer and easier to mill than the native hardwoods. Because of this, when early settlers used wood from the trees to build homes and cleared land for agriculture, the population was "decimated". Prior to restoration efforts, the pine survived only in scattered stands between Hillsboro and Cottage Grove.

Willamette Valley
The Willamette Valley ( ) is a long valley in Oregon, in the Pacific Northwest region of the United States. The Willamette River flows the entire length of the valley and is surrounded by mountains on three sides: the Cascade Range to the east, the Oregon Coast Range to the west, and the Calapooya Mountains to the south. The valley is synonymous with the cultural and political heart of Oregon and is home to approximately 70 percent of its population including the five largest cities in the state: Portland, Eugene, Salem, Gresham, and Hillsboro. The valley's numerous waterways, particularly the Willamette River, are vital to the economy of Oregon, as they continuously deposit highly fertile alluvial soils across its broad, flat plain. A massively productive agricultural area, the valley was widely publicized in the 1820s as a "promised land of flowing milk and honey." Throughout the 19th century, it was the destination of choice for the oxen-drawn wagon trains of emigra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oregon
Oregon () is a state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many indigenous nations for thousands of years. The first European traders, explorers, and settlers began exploring what is now Oregon's Pacific coast in the early-mid 16th century. As early as 1564, the Spanish began sending vessels northeast from the Philippines, riding the Kuroshio Current in a sweeping circular route across the northern part of the Pacific. In 1592, Juan de Fuca undertook detailed mapping and studies of ocean currents in the Pacific Northwest, including the Oregon coast as well as the strait now bearing his name. Spanish ships – 250 in as many years – would typically not land before reaching Cape M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Western Oregon
Western Oregon is a geographical term that is generally taken to mean the part of the U.S. state of Oregon within of the Oregon Coast, on the west side of the crest of the Cascade Range. The term is applied somewhat loosely, however, and is sometimes taken to exclude the southwestern areas of the state, which are often referred to as "Southern Oregon". In that case, "Western Oregon" means only the counties west of the Cascades and north of and including Lane County. Western Oregon, being in area, is about the same size as New England minus Maine. Unlike the climate of Eastern Oregon, which is primarily dry and continental, the climate of Western Oregon is generally a moderate Mediterranean climate. See also * Northwest Oregon Northwest Oregon is a geographic and cultural region of the U.S. state of Oregon, composed of Clatsop, Columbia, and Tillamook counties.

Douglas-fir
The Douglas fir (''Pseudotsuga menziesii'') is an evergreen conifer species in the pine family, Pinaceae. It is native to western North America and is also known as Douglas-fir, Douglas spruce, Oregon pine, and Columbian pine. There are three varieties: coast Douglas-fir (''P. menziesii'' var. ''menziesii''), Rocky Mountain Douglas-fir (''P. menziesii'' var. ''glauca'') and Mexican Douglas-fir (''P. menziesii'' var. ''lindleyana''). Despite its common names, it is not a true fir (genus '' Abies''), spruce (genus '' Picea''), or pine (genus ''Pinus''). It is also not a hemlock; the genus name ''Pseudotsuga'' means "false hemlock". Description Douglas-firs are medium-size to extremely large evergreen trees, tall (although only ''Pseudotsuga menziesii var. menziesii'', common name coast Douglas-firs, reach heights near 100 m) and commonly reach in diameter, although trees with diameters of almost exist. The largest coast Douglas-firs regularly live over 500 years, with th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hillsboro, Oregon
Hillsboro ( ) is the fifth-largest city in the U.S. state of Oregon and is the county seat of Washington County. Situated in the Tualatin Valley on the west side of the Portland metropolitan area, the city hosts many high-technology companies, such as Intel, locally known as the Silicon Forest. At the 2020 census, the city's population was 106,447. For thousands of years the Atfalati tribe of the Kalapuya lived in the Tualatin Valley near the later site of Hillsboro. The climate, moderated by the Pacific Ocean, helped make the region suitable for fishing, hunting, food gathering, and agriculture. Settlers founded a community here in 1842, later named after David Hill, an Oregon politician. Transportation by riverboat on the Tualatin River was part of Hillsboro's settler economy. A railroad reached the area in the early 1870s and an interurban electric railway about four decades later. These railways, as well as highways, aided the slow growth of the city to about 2,000 peo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cottage Grove, Oregon
Cottage Grove is a city in Lane County, Oregon, United States. Its population was 10,643 at the 2020 census. It is the third largest city in Lane County. It is on Interstate 5, Oregon Route 99, and the main Willamette Valley line of the CORP railroad. History Cottage Grove post office was established in 1855 east of present-day Creswell. It was named by its first postmaster, G. C. Pearce, whose home was in an oak grove. In 1861, the office was moved to the present site of Saginaw; then in the late 1860s, to the southwestern-most part of present-day Cottage Grove, on the west bank of the Coast Fork Willamette River. When the Southern Pacific railroad was built through the area in the 1870s, Cottage Grove station was placed more than half a mile northeast of the post office, on the river's east side. This was the start of a neighborhood dispute that lasted for nearly 20 years. The people living near the post office did not want it moved to the railroad station, so a new office was ...

Lewis's Woodpecker
Lewis's woodpecker (''Melanerpes lewis'') is a large North American species of woodpecker which ornithologist Alexander Wilson named after Meriwether Lewis, one of the explorers who surveyed the areas bought by the United States of America as part of the Louisiana Purchase and discovered this species of bird. Taxonomy Lewis's woodpecker was described and illustrated in 1811 by the American ornithologist Alexander Wilson in his ''American Ornithology; or, the Natural History of the Birds of the United States''. Wilson based his description on some bird skins that had been collected on an expedition across the western portion of the United States led by Meriwether Lewis and William Clark in 1803–1806. Wilson coined the English name "Lewis's woodpecker" and the binomial name ''Picus torquatus''. Unfortunately, the specific epithet was preoccupied by the ringed woodpecker, ''Celeus torquatus'' (Boddaert, 1783) and so in 1849 the English zoologist George Robert Gray coined a new ...

Pinus
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS.

Trees Of The Northwestern United States
In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a trunk and branches as a way to tower above other plants to compete for sunlight. The majority of tree species are angiosperms or hardwoods; of the rest, many are gymnosperms or softwoods. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years. It is estimated that there are some three trillion mature trees in the world. A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
