Krumholtz
''Krummholz'' (german: krumm, "crooked, bent, twisted" and ''Holz'', "wood") — also called ''knieholz'' ("knee timber") — is a type of stunted, deformed vegetation encountered in the subarctic and subalpine tree line landscapes, shaped by continual exposure to fierce, freezing winds. Under these conditions, trees can only survive where they are sheltered by rock formations or snow cover. As the lower portion of these trees continues to grow, the coverage becomes extremely dense near the ground. In Newfoundland and Labrador, the formation is known as tuckamore. ''Krummholz'' trees are also found on beaches such as the Oregon coast, where trees can become much taller than their subalpine cousins. Species Common trees showing ''krummholz'' formation include European spruce, mountain pine, balsam fir, red spruce, black spruce, subalpine fir, subalpine larch, Engelmann spruce, whitebark pine, limber pine, Bristlecone pine, and lodgepole pine. Instances of the ''krummholz'' for ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pinus Albicaulis 7872
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. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue River-Si ...

Whitebark Pine
''Pinus albicaulis'', known by the common names whitebark pine, white bark pine, white pine, pitch pine, scrub pine, and creeping pine, is a conifer tree native to the mountains of the western United States and Canada, specifically subalpine areas of the Sierra Nevada, Cascade Range, Pacific Coast Ranges, and Rocky Mountains. It shares the common name "creeping pine" with several other plants. The whitebark pine is typically the highest-elevation pine tree found in these mountain ranges and often marks the tree line. Thus, it is often found as ''krummholz'', trees growing close to the ground that have been dwarfed by exposure. In more favorable conditions, the trees may grow to in height. Identification Whitebark pine is a member of the white pine group, the ''Pinus'' subgenus ''Strobus'', and the section ''Strobus''; like all members of this group, the leaves (needles) are in fascicles (bundles) of five with a deciduous sheath. This distinguishes whitebark pine and its r ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pinus Flexilis
''Pinus flexilis'', the limber pine, is a species of pine tree-the family Pinaceae that occurs in the mountains of the Western United States, Mexico, and Canada. It is also called Rocky Mountain white pine. A limber pine in Eagle Cap Wilderness, Oregon, has been documented as over 2,000 years old, and another one was confirmed at 1,140 years old. Another candidate for the oldest limber pine was identified in 2006 near the Alta Ski Area in Utah; called "Twister", the tree was confirmed to be at least 1,700 years old and thought to be even older. Description Its pliant branches gives it the common name "limber" and specific epithet ''flexilis''. Its needles are about long and a dark, blueish green. Its bark is heavily creased and dark grey. Its pale wood is lightweight and soft. ''Pinus flexilis'' is typically a high-elevation pine, often marking the tree line either on its own, or with whitebark pine (''Pinus albicaulis''), either of the bristlecone pines, or lodgepole pine ...

Larix Lyallii
''Larix lyallii'', the subalpine larch, or simply alpine larch, is a deciduous, coniferous tree native to northwestern North America. It lives at high altitudes, from , in the Rocky Mountains of Idaho, Montana, British Columbia, and Alberta. There is a disjunct population in the Cascade Range of Washington. Subalpine larch is hardy and can survive at low temperatures and on thin rocky soils, often being found near the tree line. It can grow in a variety of soils as long as the soil is moist but well drained. However, it is relatively shade intolerant. David Lyall seems to have discovered the species between 1858 and 1861. John Bernhard Leiberg described it in 1900. Description ''Larix lyallii'' is a small tree, growing from tall and shorter at higher elevations. It has a straight trunk with a sparse and somewhat conical crown. The branches are horizontal, perpendicular to the trunk, irregularly spaced and twisted. The twigs are finely hairy. The needles are four-angled, lo ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pinophyta
Conifers are a group of cone-bearing seed plants, a subset of gymnosperms. Scientifically, they make up the division Pinophyta (), also known as Coniferophyta () or Coniferae. The division contains a single extant class, Pinopsida. All extant conifers are perennial woody plants with secondary growth. The great majority are trees, though a few are shrubs. Examples include cedars, Douglas-firs, cypresses, firs, junipers, kauri, larches, pines, hemlocks, redwoods, spruces, and yews.Campbell, Reece, "Phylum Coniferophyta". Biology. 7th. 2005. Print. P. 595 As of 1998, the division Pinophyta was estimated to contain eight families, 68 genera, and 629 living species. Although the total number of species is relatively small, conifers are ecologically important. They are the dominant plants over large areas of land, most notably the taiga of the Northern Hemisphere, but also in similar cool climates in mountains further south. Boreal conifers have many wintertime adaptations. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Vermont
Vermont () is a state in the northeast New England region of the United States. Vermont is bordered by the states of Massachusetts to the south, New Hampshire to the east, and New York to the west, and the Canadian province of Quebec to the north. Admitted to the union in 1791 as the 14th state, it is the only state in New England not bordered by the Atlantic Ocean. According to the 2020 U.S. census, the state has a population of 643,503, ranking it the second least-populated in the U.S. after Wyoming. It is also the nation's sixth-smallest state in area. The state's capital Montpelier is the least-populous state capital in the U.S., while its most-populous city, Burlington, is the least-populous to be a state's largest. For some 12,000 years, indigenous peoples have inhabited this area. The competitive tribes of the Algonquian-speaking Abenaki and Iroquoian-speaking Mohawk were active in the area at the time of European encounter. During the 17th century, Fr ...

Green Mountains
The Green Mountains are a mountain range in the U.S. state of Vermont. The range runs primarily south to north and extends approximately from the border with Massachusetts to the border with Quebec, Canada. The part of the same range that is in Massachusetts and Connecticut is known as The Berkshires or the Berkshire Hills (with the Connecticut portion, mostly in Litchfield County, locally called the Northwest Hills or Litchfield Hills) and the Quebec portion is called the Sutton Mountains, or ' in French. All mountains in Vermont are often referred to as the "Green Mountains". However, other ranges within Vermont, including the Taconic Mountains in southwestern Vermont and the Northeastern Highlands, are not geologically part of the Green Mountains. Peaks The best-known mountains—for reasons such as high elevation, ease of public access by road or trail (especially the Long Trail and Appalachian Trail), or with ski resorts or towns nearby—in the range include: # Mount ...

White Mountains (New Hampshire)
The White Mountains are a mountain range covering about a quarter of the state of New Hampshire and a small portion of western Maine in the United States. They are part of the northern Appalachian Mountains and the most rugged mountains in New England. The range is heavily visited due to its proximity to Boston, New York City, and Montreal. Most of the area is public land, including the White Mountain National Forest and a number of state parks. Its most famous mountain is Mount Washington, which is the highest peak in the Northeastern U.S. and for 76 years held the record for fastest surface wind gust in the world ( in 1934). Mount Washington is part of a line of summits, the Presidential Range, that are named after U.S. presidents and other prominent Americans. The White Mountains also include the Franconia Range, Sandwich Range, Carter-Moriah Range and Kinsman Range in New Hampshire, and the Mahoosuc Range straddling the border between it and Maine. In all, there are 48 peak ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Boreal Forest
Taiga (; rus, тайга́, p=tɐjˈɡa; relates to Mongolic and Turkic languages), generally referred to in North America as a boreal forest or snow forest, is a biome characterized by coniferous forests consisting mostly of pines, spruces, and larches. The taiga or boreal forest has been called the world's largest land biome. In North America, it covers most of inland Canada, Alaska, and parts of the northern contiguous United States. In Eurasia, it covers most of Sweden, Finland, much of Russia from Karelia in the west to the Pacific Ocean (including much of Siberia), much of Norway and Estonia, some of the Scottish Highlands, some lowland/coastal areas of Iceland, and areas of northern Kazakhstan, northern Mongolia, and northern Japan (on the island of Hokkaidō). The main tree species, depending on the length of the growing season and summer temperatures, vary across the world.
