Pinus Ponderosa
''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 Unpublished report.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 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 misidentified it as ' ...

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, Scone, Perthshire, the second son of John Douglas, a stonemason, and Jean Drummond. At around the age of seven, he attended a school in a neighboring parish, where he became known for his tardiness and truancy, preferring to explore the countryside during his two-mile walk to class. He attended school in Kinnoull, on the eastern banks of the River Tay, and upon leaving found work as an apprentice to William Beattie, head gardener at nearby Scone Palace, the seat of the David William Murray, 3rd Earl of Mansfield, 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 ...

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 fasc ...

Natural Resources Conservation Service
Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers. Its name was changed in 1994 during the presidency of Bill Clinton to reflect its broader mission. It is a relatively small agency, currently comprising about 12,000 employees. Its mission is to improve, protect, and conserve natural resources on private lands through a cooperative partnership with State governments of the United States, state and Local government in the United States, local agencies. While its primary focus has been agriculture, agricultural lands, it has made many technical contributions to soil surveying, soil classification, classification, and water quality improvement. One example is the Conservation Effects Assessment Project (CEAP), set up to quantify the benefits of agricultural conservation efforts pr ...

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Author Citation (botany)
In botanical nomenclature, author citation is the way of citing the person or group of people who validly published a botanical name, i.e. who first published the name while fulfilling the formal requirements as specified by the ''International Code of Nomenclature for algae, fungi, and plants'' (''ICN''). In cases where a species is no longer in its original generic placement (i.e. a new combination of genus and specific epithet), both the authority for the original genus placement and that for the new combination are given (the former in parentheses). In botany, it is customary (though not obligatory) to abbreviate author names according to a recognised List of botanists by author abbreviation, list of standard abbreviations. There are differences between the botanical code and the normal Author citation (zoology), practice in zoology. In zoology, the publication year is given following the author names and the authorship of a new combination is normally omitted. A small number o ...

Arborist
An arborist, or (less commonly) arboriculturist, is a professional in the practice of arboriculture, which is the Plant cultivation, 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 (silviculture or forestry). An arborist's scope of work is therefore distinct from that of either a forester or a lumberjack, 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).

Michael Taylor (forester)
Michael W. Taylor (born 25 April 1966) is an American forester who is notable for being a leading discoverer of champion and tallest trees - most notably coast Sequoia sempervirens, redwoods. In 2006, Taylor co-discovered the tallest known tree in the world, a coast redwood (''Sequoia sempervirens'') now named "Hyperion (tree), 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 C. Sillett, 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.
