Native Trees In Toronto
Native trees in Toronto are trees that are naturally growing in Toronto and were not later introduced by humans. The area that presently comprise Toronto is a part of the Carolinian forest, although agricultural and urban developments destroyed significant portions of that life zone. In addition, many of Toronto's native trees have been displaced by non-native plants and trees introduced by settlers from Europe and Asia from the 18th century to the present. Most of the native trees are found in the Toronto ravine system, parks, and along the Toronto waterway system. The type of trees growing across the city varies based on the soil condition in the area. Tree cover in the city prior to European settlement started from the shore line back. Settlement resulted in trees being cut for use in building homes and ships and for heating by early residents. The current tree cover (or canopy) in Toronto is estimated to be between 26.6 and 28% and many trees are not native to the city. The city ...

Populus Grandidentata
''Populus grandidentata'', commonly called large-tooth aspen, big-tooth aspen, American aspen, Canadian poplar, or white poplar, is a deciduous tree native to eastern North America. Name The name ''Populus'' is from the Latin for poplar, and ''grandidentata'' refers to the coarse teeth on the leaves (''grandis'' meaning "large", and ''dentata'' meaning "toothed"). Description ''Populus grandidentata'' is a medium-sized deciduous tree native to North America, found mostly in the northeastern United States and southeastern Canada. Leaves are similar to ''Populus tremuloides'', but slightly larger and having larger teeth. The leaves tremble in the wind as ''P. tremuloides'' does. Bark of younger trees is olive-green, thin and smooth; after 30–40 years, the bark is gray, thick and rough with grooves. Reproduction Bigtooth aspens produce seeds from wind-pollinated flower clusters, known as catkins. The tree is dioecious, meaning that male and female flowers are on separate tr ...

Cornus
''Cornus'' is a genus of about 30–60 species of woody plants in the family Cornaceae, commonly known as dogwoods, which can generally be distinguished by their blossoms, berries, and distinctive bark. Most are deciduous trees or shrubs, but a few species are nearly herbaceous perennial subshrubs, and some species are evergreen. Several species have small heads of inconspicuous flowers surrounded by an involucre of large, typically white petal-like bracts, while others have more open clusters of petal-bearing flowers. The various species of dogwood are native throughout much of temperate and boreal Eurasia and North America, with China, Japan, and the southeastern United States being particularly rich in native species. Species include the common dogwood ''Cornus sanguinea'' of Eurasia, the widely cultivated flowering dogwood ''(Cornus florida)'' of eastern North America, the Pacific dogwood ''Cornus nuttallii'' of western North America, the Kousa dogwood ''Cornus kous ...

American Chestnut
The American chestnut (''Castanea dentata'') is a large, fast-growing deciduous tree of the beech family native to eastern North America. As is true of all species in genus Castanea, the American chestnut produces burred fruit with edible nuts. The American chestnut was one of the most important forest trees throughout its range and was considered the finest chestnut tree in the world.Davis, Donald E"Historical Significance of American Chestnut on Appalachian Culture and Ecology" ''www.ecosystem.psu.edu'', 2005. Retrieved October 28, 2015. During the early to mid 20th century, American chestnut trees were devastated by chestnut blight, a fungal disease that came from Chinese chestnut trees that were introduced into North America from East Asia. It is estimated that the blight killed between 3 and 4 billion American chestnut trees in the first half of the 20th century, beginning in 1904.Griffin, Gary"Recent advances in research and management of chestnut blight on American chest ...

Chestnut
The chestnuts are the deciduous trees and shrubs in the genus ''Castanea'', in the beech family Fagaceae. They are native to temperate regions of the Northern Hemisphere. The name also refers to the edible nuts they produce. The unrelated horse chestnuts (genus ''Aesculus'') are not true chestnuts, but are named for producing nuts of similar appearance that are mildly poisonous to humans. True chestnuts should also not be confused with water chestnuts, which are tubers of an aquatic herbaceous plant in the sedge family Cyperaceae. Other species commonly mistaken for chestnut trees are the chestnut oak ('' Quercus prinus'') and the American beech (''Fagus grandifolia''),Chestnut Tree in chestnuttree.net. both of which are also in the Fagaceae family. |
Thuja Occidentalis
''Thuja occidentalis'', also known as northern white-cedar, eastern white-cedar, or arborvitae, is an evergreen coniferous tree, in the cypress family Cupressaceae, which is native to eastern Canada and much of the north-central and northeastern United States. It is widely cultivated as an ornamental plant. Common names Its additional common names include swamp cedar, American arborvitae, and eastern arborvitae. The name arborvitae is particularly used in the horticultural trade in the United States; it is Latin for 'tree of life' – due to the supposed medicinal properties of the sap, bark, and twigs.''Thuja'', American Cancer Society, last revised 6/19/2007available online/ref> It is sometimes called white-cedar (hyphenated) or whitecedar (one word) to distinguish it from ''Cedrus'', a distantly related genus of trees also known as cedars. Description Unlike the closely related western red cedar (''Thuja plicata''), northern white cedar is only a small or medium-sized tree ...

Thuja
''Thuja'' ( ) is a genus of coniferous tree or shrub in the Cupressaceae (cypress family). There are five species in the genus, two native to North America and three native to eastern Asia. The genus is monophyletic and sister to ''Thujopsis''. Members are commonly known as arborvitaes (from the Latin term for 'tree of life'), thujas or cedars. Description ''Thuja'' are evergreen trees growing from tall, with stringy-textured reddish-brown bark. The shoots are flat, with side shoots only in a single plane. The leaves are scale-like and long, except young seedlings in their first year, which have needle-like leaves. The scale leaves are arranged in alternating decussate pairs in four rows along the twigs. The male cones are small, inconspicuous, and are located at the tips of the twigs. The female cones start out similarly inconspicuous, but grow to about long at maturity when 6–8 months old; they have 6-12 overlapping, thin, leathery scales, each scale bearing 1–2 small se ...

Fagus Grandifolia
''Fagus grandifolia'', the American beech or North American beech, is a species of beech tree native to the eastern United States and extreme southeast of Canada. Description ''Fagus grandifolia'' is a large deciduous tree growing to tall, with smooth, silver-gray bark. The leaves are dark green, simple and sparsely-toothed with small teeth that terminate each vein, long (rarely ), with a short petiole. The winter twigs are distinctive among North American trees, being long and slender ( by ) with two rows of overlapping scales on the buds. Beech buds are distinctly thin and long, resembling cigars; this characteristic makes beech trees relatively easy to identify. The tree is monoecious, with flowers of both sexes on the same tree. The fruit is a small, sharply-angled nut, borne in pairs in a soft-spined, four-lobed husk. It has two means of reproduction: one is through the usual dispersal of seedlings, and the other is through root sprouts, which grow into new trees. ...

Beech
Beech (''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to temperate Europe, Asia, and North America. Recent classifications recognize 10 to 13 species in two distinct subgenera, ''Engleriana'' and ''Fagus''. The ''Engleriana'' subgenus is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known ''Fagus'' subgenus beeches are high-branching with tall, stout trunks and smooth silver-grey bark. The European beech (''Fagus sylvatica'') is the most commonly cultivated. Beeches are monoecious, bearing both male and female flowers on the same plant. The small flowers are unisexual, the female flowers borne in pairs, the male flowers wind-pollinating catkins. They are produced in spring shortly after the new leaves appear. The fruit of the beech tree, known as beechnuts or mast, is found in small burrs that drop from the tree in autumn. They are small, roughly triangular, and edible, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betula Alleghaniensis
''Betula alleghaniensis'', the yellow birch, golden birch, or swamp birch, is a large tree and an important lumber species of birch native to northeastern North America. Its vernacular names refer to the golden color of the tree's bark. In the past the species name was ''Betula lutea''. ''Betula alleghaniensis'' is the provincial tree of Quebec, where it is commonly called ''merisier'', a name which in France is used for the wild cherry. Description It is a medium-sized, typically single stemmed, deciduous tree reaching tall (exceptionally to ) with a trunk typically in diameter, making it the largest North American species of birch. Yellow birch is long-lived, typically 150 years and some old growth forest specimens may last for 300 years. It mostly reproduces by seed. Mature trees typically start producing seeds at about 40 years but may start as young as 20. The optimum age for seed production is about 70 years. Good seed crops are not produced every year, and tend to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betula Papyrifera
''Betula papyrifera'' (paper birch, also known as (American) white birch and canoe birch) is a short-lived species of birch native to northern North America. Paper birch is named for the tree's thin white bark, which often peels in paper like layers from the trunk. Paper birch is often one of the first species to colonize a burned area within the northern latitudes, and is an important species for moose browsing. The wood is often used for pulpwood and firewood. Description It is a medium-sized deciduous tree typically reaching tall, and exceptionally to with a trunk up to in diameter. Within forests, it often grows with a single trunk but when grown as a landscape tree it may develop multiple trunks or branch close to the ground. Paper birch is a typically short-lived species. It handles heat and humidity poorly and may live only 30 years in zones six and up, while trees in colder-climate regions can grow for more than 100 years. ''B. papyrifera'' will grow in many so ...

Birch
A birch is a thin-leaved deciduous hardwood tree of the genus ''Betula'' (), in the family Betulaceae, which also includes alders, hazels, and hornbeams. It is closely related to the beech-oak family Fagaceae. The genus ''Betula'' contains 30 to 60 known taxa of which 11 are on the IUCN 2011 Red List of Threatened Species. They are a typically rather short-lived pioneer species widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Description Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. The fruit is a small samara, although the wings may be obscure in some species. They differ from the alders (''Alnus'', another genus in the family) in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
