Ponderosa Pine
''Pinus ponderosa'', commonly known as the ponderosa pine, bull pine, blackjack pine, western yellow-pine, or filipinus pine is a very large pine tree species of variable habitat native to mountainous regions of western North America. It is the most widely distributed pine species in North America.Safford, H.D. 2013. Natural Range of Variation (NRV) for yellow pine and mixed conifer forests in the bioregional assessment area, including the Sierra Nevada, southern Cascades, and Modoc and Inyo National Forests. Unpublished report. USDA Forest Service, Pacific Southwest Region, Vallejo, CA/ref> ''Pinus ponderosa'' grows in various erect forms from British Columbia southward and eastward through 16 western U.S. states and has been successfully introduced in temperate regions of Europe, and in New Zealand. It was first documented in modern science in 1826 in eastern Washington near present-day Spokane (of which it is the official city tree). On that occasion, David Douglas misidenti ...

Montana
Montana () is a state in the Mountain West division of the Western United States. It is bordered by Idaho to the west, North Dakota and South Dakota to the east, Wyoming to the south, and the Canadian provinces of Alberta, British Columbia, and Saskatchewan to the north. It is the fourth-largest state by area, the eighth-least populous state, and the third-least densely populated state. Its state capital is Helena. The western half of Montana contains numerous mountain ranges, while the eastern half is characterized by western prairie terrain and badlands, with smaller mountain ranges found throughout the state. Montana has no official nickname but several unofficial ones, most notably "Big Sky Country", "The Treasure State", "Land of the Shining Mountains", and " The Last Best Place". The economy is primarily based on agriculture, including ranching and cereal grain farming. Other significant economic resources include oil, gas, coal, mining, and lumber. The health ca ...

David Douglas (botanist)
David Douglas (25 June 1799 – 12 July 1834) was a Scottish botanist, best known as the namesake of the Douglas fir. He worked as a gardener, and explored the Scottish Highlands, North America, and Hawaii, where he died. Early life Douglas was born in Scone, Perthshire, the second son of John Douglas, a stonemason, and Jean Drummond. He attended Kinnoull School and upon leaving found work as an apprentice to William Beattie, head gardener at Scone Palace, the seat of the Earl of Mansfield. He spent seven years in this position, completing his apprenticeship, and then spent a winter at a college in Perth to learn more of the scientific and mathematical aspects of plant culture. After a further spell of working at Valleyfield House in Fife (during which time he had access to a library of botanical and zoological books) he moved to the Botanical Gardens of Glasgow University and attended botany lectures. William Jackson Hooker, who was Garden Director and Professor of Bot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fascicle (botany)
In botany, a fascicle is a bundle of leaves or flowers growing crowded together; alternatively the term might refer to the vascular tissues that supply such an organ with nutrients.Shashtri, Varun. Dictionary of Botany. Publisher: Isha Books 2005. However, vascular tissues may occur in fascicles even when the organs they supply are not fascicled. Etymology of fascicle and related terms The term ''fascicle'' and its derived terms such as ''fasciculation'' are from the Latin ''fasciculus'', the diminutive of ''fascis'', a bundle. Accordingly, such words occur in many forms and contexts wherever they are convenient for descriptive purposes. A fascicle may be leaves or flowers on a short shoot where the nodes of a shoot are crowded without clear internodes, such as in species of ''Pinus'' or '' Rhigozum''. However, bundled fibres, nerves or bristles as in tissues or the glochid fascicles of '' Opuntia'' may have little or nothing to do with branch morphology. In pines Leaf fascicle ...

George Engelmann
George Engelmann, also known as Georg Engelmann, (2 February 1809 – 4 February 1884) was a German-American botanist. He was instrumental in describing the flora of the west of North America, then very poorly known to Europeans; he was particularly active in the Rocky Mountains and northern Mexico, one of his constant companions being another German-American, the botanical illustrator Paulus Roetter. Biography Origins George Engelmann was born in Frankfurt am Main, Germany, the oldest of thirteen children, nine of whom reached maturity. His father, Julius Bernhardt Engelmann, was a member of a family from which for several successive generations were chosen ministers for the Reformed Church at Bacharach-on-the-Rhine. Julius was a graduate of the University of Halle, and was also educated for the ministry, but he devoted his life to education. He established a school for young women in Frankfurt, which was rare at the time. George Engelmann's mother, Julie Antoinette, was the ...

Forestry
Forestry is the science and craft of creating, managing, planting, using, conserving and repairing forests, woodlands, and associated resources for human and environmental benefits. Forestry is practiced in plantations and natural stands. The science of forestry has elements that belong to the biological, physical, social, political and managerial sciences. Forest management play essential role of creation and modification of habitats and affect ecosystem services provisioning. Modern forestry generally embraces a broad range of concerns, in what is known as multiple-use management, including: the provision of timber, fuel wood, wildlife habitat, natural water quality management, recreation, landscape and community protection, employment, aesthetically appealing landscapes, biodiversity management, watershed management, erosion control, and preserving forests as " sinks" for atmospheric carbon dioxide. Forest ecosystems have come to be seen as the most important componen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxa
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinus Lambertiana
''Pinus lambertiana'' (commonly known as the sugar pine or sugar cone pine) is the tallest and most massive pine tree, and has the longest cones of any conifer. The species name ''lambertiana'' was given by the Scottish botanist David Douglas, who named the tree in honour of the English botanist, Aylmer Bourke Lambert. It is native to coastal and inland mountain areas along the Pacific coast of North America, as far north as Oregon and as far south as Baja California in Mexico. Description Growth The sugar pine is the tallest and largest ''Pinus'' species, commonly growing to tall, exceptionally to tall, with a trunk diameter of , exceptionally . The tallest recorded specimen is tall, is located in Yosemite National Park, and was discovered in 2015. The second tallest recorded was "Yosemite Giant", an tall specimen in Yosemite National Park, which died from a bark beetle attack in 2007. The tallest known living specimens today grow in southern Oregon and Yosemite Nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portland, Oregon
Portland (, ) is a port city in the Pacific Northwest and the largest city in the U.S. state of Oregon. Situated at the confluence of the Willamette and Columbia rivers, Portland is the county seat of Multnomah County, the most populous county in Oregon. Portland had a population of 652,503, making it the 26th-most populated city in the United States, the sixth-most populous on the West Coast, and the second-most populous in the Pacific Northwest, after Seattle. Approximately 2.5 million people live in the Portland metropolitan statistical area (MSA), making it the 25th most populous in the United States. About half of Oregon's population resides within the Portland metropolitan area. Named after Portland, Maine, the Oregon settlement began to be populated in the 1840s, near the end of the Oregon Trail. Its water access provided convenient transportation of goods, and the timber industry was a major force in the city's early economy. At the turn of the 20th century, the ...

Oregon
Oregon () is a U.S. state, state in the Pacific Northwest region of the Western United States. The Columbia River delineates much of Oregon's northern boundary with Washington (state), Washington, while the Snake River delineates much of its eastern boundary with Idaho. The 42nd parallel north, 42° north parallel delineates the southern boundary with California and Nevada. Oregon has been home to many Indigenous peoples of the Americas, 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 expeditions to the Pacific Northwest, 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 ...

Arborist
An arborist, tree surgeon, or (less commonly) arboriculturist, is a professional in the practice of arboriculture, which is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants in dendrology and horticulture. Arborists generally focus on the health and safety of individual plants and trees, rather than managing forests or harvesting wood (forestry or silviculture). An arborist's scope of work is therefore distinct from that of either a forester or a logger. Scope of work In order for arborists to work near power wires, either additional training is required or they need to be certified as a Qualified Line Clearance Arborist or Utility Arborist (there may be different terminology for various countries). There is a variety of minimum distances that must be kept from power wires depending on voltage, however the common distance for low voltage lines in urban settings is 10 feet (about 3 metres). Arborists who climb (as no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Michael Taylor (forester)
Michael W. Taylor (born 25 April 1966, in Los Angeles) is a leading discoverer of champion and tallest trees - most notably coast redwoods. In 2006, Taylor co-discovered the tallest known tree in the world, a coast redwood (''Sequoia sempervirens'') now named " Hyperion". He also discovered "Helios" and "Icarus", the 2nd and 3rd tallest. National Geographic made a video about the discovery and measuring of Hyperion. The discovery made headlines. Taylor has discovered 50 coast redwoods over tall, and co-discovered approximately 100 more with Chris Atkins and Stephen Sillett, who is the first holder of the Kenneth L. Fisher Chair in Redwood Forest Ecology at Humboldt State University. Taylor and Sillett have collaborated and measured remarkable previously unknown redwoods. Their discoveries have fueled research and public interest in coast redwoods, which are now a World Heritage Site. Michael is a main character of the non-fiction book (2007) ''The Wild Trees''.
