Query: What does it mean to be an evergreen tree?
Trees are either evergreen, having foliage that persists and remains green throughout the year, or deciduous, shedding their leaves at the end of the growing season and then having a dormant period without foliage. Most conifers are evergreens, but larches ("Larix" and "Pseudolarix") are deciduous, dropping their needles each autumn, and some species of cypress ("Glyptostrobus", "Metasequoia" and "Taxodium") shed small leafy shoots annually in a process known as cladoptosis. The crown is a name for the spreading top of a tree including the branches and leaves, while the uppermost layer in a forest, formed by the crowns of the trees, is known as the canopy. A sapling is a young tree.
Discovered in 1997 and located near one of the Big Brook tributaries, The Marlboro Tree, a massive black willow tree has been certified by the New Jersey Forest Service as a "State Champion" tree, signifying that it is the largest known tree of its species in the State of New Jersey, and the largest tree of any kind in Marlboro Township. It is about 152 years old and measures high and 19' 8" in circumference. Five grown people must hold hands to fully encircle the tree.
The Marlboro Tree, located in Marlboro Township, New Jersey is certified by the State of New Jersey as the largest known example of this tree in the state. It is about 152 years old and measures in height and in circumference. Five grown people must hold hands to fully encircle the tree.
In the U.S. Pacific Northwest, a major Christmas tree growing region, Douglas-fir has always been the primary species grown. A full one-half of all trees produced in the Pacific Northwest are Douglas-fir. Douglas-firs typically take five to seven years before they are mature enough to sell as Christmas trees. Also common in the region are noble fir, a tree which commands a higher price than Douglas-fir, and grand fir, which accounts for about 10 percent of the annual harvest in the Northwest. Other species collectively account for only 3–5 percent of the total Northwest harvest.
The life cycle of a Christmas tree from the seed to a tree takes, depending on species and treatment in cultivation, between 8 and 12 years. First, the seed is extracted from cones harvested from older trees. These seeds are then usually grown in nurseries and then sold to Christmas tree farms at an age of 3–4 years. The remaining development of the tree greatly depends on the climate, soil quality, as well as the cultivation and how the trees are tended by the Christmas tree farmer.
It is classified as one of the five great cherry trees of Japan (日本五大桜) and one of the three giant cherry trees of Japan (日本三巨大桜). It was designated a national treasure in 1922. Polls frequently rank it as the number one tree in all of Japan.
The Angel Oak is a living Southern live oak tree located on Johns Island. Estimates of the tree's age range from 400 to 1500 years old. The oak is tall, with a trunk circumference of . In spite of the popular belief that the Angel Oak is the oldest tree east of the Mississippi River, there are many baldcypress trees throughout the south which are many hundreds of years older. The Angel Oak stands on part of the land given to Jacob Waight in 1717 as part of a land grant. The Angel Oak was acquired by the City of Charleston in 1991. Today, Angel Oak Park provides visitors a close look at the tree. The park area is complete with a gift shop and picnic tables.
In addition to beech, the oak is another characteristic tree of the Palatinate Forest, albeit botanically speaking they are mainly sessile oak rather than English oak. It is the main tree species of larger, sometimes centuries-old, stands in the regions around Johanniskreuz, Eschkopf and Weißenberg and may also be found further south between Fischbach and Eppenbrunn, where, as well as the plateaus of the central Palatinate Forest, it prefers sunnier slopes (west to south-east facing slopes). But in the rest of Palatinate Forest, it is on the increase and usually forms, together with beech, often very natural, primeval, mixed forest (natural forest), which enjoys special protection as a core zone of the Palatine Forest-North Vosges Biosphere Reserve (see biosphere reserve). In addition, from a forestry point of view the oaks of the Palatinate Forest are a particularly high priority because the wood veneer produced from them is recognized worldwide as being of unique quality.
Despite the decline in its share of the total tree population from 44 to 34 percent in 2008, the pine continues to be a dominant species of the low mountain range. This is due to the historical background, especially in the Haardt area, where they once heavily dominated the scene with 60 to 70 percent share of the forest. It is traditionally planted on dry, sunny, south-facing slopes. Like oak and beech it is an autochthonous member of the forest community, although for the purposes of reforesting devastated areas (see forest history) pine species from other regions have been introduced and mixed with indigenous species. In Waldleiningen in the mid-Palatinate Forest and on the peaty soils at Bitche in the French part of the biosphere reserve "relict" pine forests have survived, in which the character of the original pine forest can be vividly seen.
Angel Oak is a Southern live oak ("Quercus virginiana") located in Angel Oak Park on Johns Island near Charleston, South Carolina. The tree is estimated to be 400-500 years old. It stands 66.5 ft (20 m) tall, measures 28 ft (8.5 m) in circumference, and produces shade that covers 17,200 square feet (1,600 m). Its longest branch distance is 187 ft in length. Angel Oak was the 210th tree to be registered with the Live Oak Society.
The oak derives its name from the estate of Justus Angel and his wife, Martha Waight Tucker Angel. Local folklore tells stories of ghosts of former slaves appearing as angels around the tree.
As their Sternberg household dwindled down from eight members to three, Gene began the transition from his professional practice to a new role and a new "hometown." Since 1949, the Sternbergs had enjoyed spending time in summer in a cabin they built in Evergreen, 30 miles into the foothills west of Denver. By 1970, Evergreen was in the process of transformation from a small mountain summer resort to a year-round community within commuting distance of Denver. The Sternbergs sold the cherished home that Eugene had designed for the family in Orchard Hills, and moved into an old log house on the banks of Evergreen's Upper Bear Creek, Colorado with their youngest daughter.
On 23 August 2010, the tree was blown down by high winds during a storm, breaking off approximately above ground. It fell across a garden wall and damaged garden sheds but did not damage anything else. The tree was estimated to be between 150 and 170 years old.
The coast redwood can reach tall with a trunk diameter of . It has a conical crown, with horizontal to slightly drooping branches. The bark can be very thick, up to , and quite soft and fibrous, with a bright red-brown color when freshly exposed (hence the name redwood), weathering darker. The root system is composed of shallow, wide-spreading lateral roots.
There are more than 20,000 North American Christmas tree growers, 95 percent of the trees they produce are sold or shipped directly from the farms. On each of the planted in Christmas trees annually there are usually about 2,000 trees, the number of trees that survive to harvest varies from 750–1,500 depending upon location. Christmas trees take an average of 6 to 10 years (from transplant) to mature for harvest and each year 73 million new Christmas trees are planted.
In the lower elevations and canyons, the California Redwood is often found. Its thick bark, along with foliage that starts high above the ground, protect the species from both fire and insect damage, contributing to the coast redwood's longevity. Fire appears to benefit redwoods by removing competitive species. A 2010 study compared post-wildfire survival and regeneration of redwood and associated species. It concluded that fires of all severity increase the relative abundance of redwood and higher-severity fires provide the greatest benefit.The July 2016 Soberanes Fire was caused by unknown individuals who started and lost control of an illegal campfire in the Garrapata Creek watershed. After it burned 57 homes in the Garrapata and Palo Colorado Canyon areas, fire fighters were able to build lines around parts of the Big Sur community. A bulldozer operator was killed when his equipment overturned during night operations in Palo Colorado Canyon.
Theobroma cacao, also called the cacao tree and the cocoa tree, is a small ( tall) evergreen tree in the family Malvaceae, native to the deep tropical regions of the Americas. Its seeds, cocoa beans, are used to make chocolate liquor, cocoa solids, cocoa butter and chocolate.
The roots are, generally, an underground part of the tree, but some tree species have evolved roots that are aerial. The common purposes for aerial roots may be of two kinds, to contribute to the mechanical stability of the tree, and to obtain oxygen from air. An instance of mechanical stability enhancement is the red mangrove that develops prop roots that loop out of the trunk and branches and descend vertically into the mud. A similar structure is developed by the Indian banyan. Many large trees have buttress roots which flare out from the lower part of the trunk. These brace the tree rather like angle brackets and provide stability, reducing sway in high winds. They are particularly prevalent in tropical rainforests where the soil is poor and the roots are close to the surface.
Since the Ontario forests are so plentiful the wood resource would be sustainable for some time. Most companies are doing their own part to help ensure that there is enough lumber within Ontario to support numerous generations to come. Tembec Industries has invested a large amount of time and money into planting trees. Tembec recently celebrated their 250 millionth tree planted in Ontario. The Ontario Government’s land use strategy helps protect and sustain all of Ontario’s natural resources, including wood products. The Ontario Forest Accord provides security by forcing the forest industry and the environmental community to establish protected areas, while at the same time meeting the needs of the forestry industry.
Blue-leaved stringybark is a koala food tree. A field study conducted in the Campbelltown district southwest of Sydney published in 2000 found that koalas preferred Blue-leaved Stringybark and Grey Gum but only when the two tree species were growing on shale-based rather than sandstone soils. Stringybarks are some of the most difficult of all eucalyptus plants to identify. However, the bluish colour of the leaves makes this species fairly easy to identify.
It is 22 metres high and 47 metres in circumference. The trunk diameter was 10.64 metres (only the Glencoe Baobab up to its 2009 split was larger), and the crown diameter is 30.2 metres. The trunk consists of two connected sections, each with its own enormous hollow, and these are connected by a narrow passage. One third of the Boabab tree collapsed in August 2016. This was ascribed to age and the natural hollowing of the trunk with time. The property owners intend to leave the fallen trunk section as it fell, allowing natural processes to reshape and assimilate the feature.
While some of the symbols are unique to Washington, others are used by multiple states. For example, the willow goldfinch (also known as the American goldfinch), Washington's state bird, is also an official symbol for Iowa and New Jersey. Washington's state grass, bluebunch wheatgrass, is also a symbol for the state of Montana. The square dance and apple are commonly used state dances and state foods, respectively. While most states have an official motto and nickname, Washington's motto ("Al-ki", meaning "by and by" in Chinook Jargon) and nickname ("The Evergreen State") have never been officially adopted by the Legislature.
Japan gave 3,020 cherry blossom trees as a gift to the United States in 1912 to celebrate the nations' then-growing friendship, replacing an earlier gift of 2,000 trees which had to be destroyed due to disease in 1910. These trees were planted in Sakura Park in Manhattan and line the shore of the Tidal Basin and the roadway in East Potomac Park in Washington, D.C. The first two original trees were planted by first lady Helen Taft and Viscountess Chinda on the bank of the Tidal Basin. The gift was renewed with another 3,800 trees in 1965. In Washington, D.C. the cherry blossom trees continue to be a popular tourist attraction (and the subject of the annual National Cherry Blossom Festival) when they reach full bloom in early spring. Just outside of Washington, D.C., the suburb of Kenwood in Bethesda, Maryland has roughly 1,200 trees that are popular with locals and tourists.
This tree's characteristics (evergreen attractive foliage; fruits that are not fleshy and therefore will not cause a mess; and a gentle non-invasive root system that will not damage paving) mean that "Apodytes dimidiata" is an ideal tree to plant around paved areas, near swimming pools, next to buildings, in small gardens and also anywhere that may need shade throughout the year.
Deciduous trees predominate in most of these forests, and during the drought a leafless period occurs, which varies with species type. Because trees lose moisture through their leaves, the shedding of leaves allows trees such as teak and mountain ebony to conserve water during dry periods. The newly bare trees open up the canopy layer, enabling sunlight to reach ground level and facilitate the growth of thick underbrush. Trees on moister sites and those with access to ground water tend to be evergreen. Infertile sites also tend to support evergreen trees. Three tropical dry broadleaf forest ecoregions, the East Deccan dry evergreen forests, the Sri Lanka dry-zone dry evergreen forests, and the Southeastern Indochina dry evergreen forests, are characterized by evergreen trees.
In Norse mythology, Yggdrasill was often seen as a giant ash tree. Many scholars now agree that in the past, an error had been made in the interpretation of the ancient writings, and that the tree is most likely a European yew ("Taxus baccata"). This mistake would find its origin in an alternative word for the yew tree in the Old Norse, namely needle ash ("barraskr"). In addition, ancient sources, including the Eddas, write about a "vetgrønster vida", which means "evergreen tree". An ash sheds its leaves in the winter, while yew trees retain their needles. The first man, Ask, was formed from the "ash tree".
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers, live oak, and holly in cold climates, eucalypts, acacias and banksias in more temperate zones, and rainforest trees in tropical zones.
