Eastern Moose
The eastern moose (''Alces alces americana'') is a subspecies of moose that currently ranges throughout Eastern Canada, New England and northern New York (state), New York State. It inhabits boreal forests and mixed deciduous forests. It is the third largest North American subspecies, after the western moose and the Alaska moose, Alaskan moose. Males are aggressive during mating season and will Moose attack, attack anything that provokes them. Distribution The eastern moose's range spans a broad swath of northeastern North America, which includes New Brunswick, Newfoundland and Labrador (while it is native to Labrador, it was introduced to Gander Bay, Newfoundland in 1878 and to Howley, NL in 1904), Nova Scotia, Quebec, Eastern Ontario, Maine, New Hampshire, Vermont, Massachusetts, Connecticut, and northern New York. The moose that roam in Cape Breton Highlands National Park are descended from the western moose that originated from Alberta, Alberta's Elk Island National Park. Th ...

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 typically short-lived pioneer species and are widespread in the Northern Hemisphere, particularly in northern areas of temperate climates and in boreal climates. Birch wood is used for a wide range of purposes. 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Willow
Willows, also called sallows and osiers, of the genus ''Salix'', comprise around 350 species (plus numerous hybrids) of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicin, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live, and roots readily sprout from aerial parts of the plant. Lea ...

Forb
A forb or phorb is a herbaceous flowering plant that is not a graminoid (grass, sedge, or rush). The term is used in botany and in vegetation ecology especially in relation to grasslands and understory. Typically, these are eudicots without woody stems. Etymology The word ''forb'' is derived from Greek () 'pasture; fodder'. The Hellenic spelling ''phorb'' is sometimes used, and in older usage this sometimes includes graminids and other plants currently not regarded as forbs. Guilds Forbs are members of a guilda group of plant species with broadly similar growth forms. In certain contexts in ecology, guild membership may often be more important than the taxonomic relationships between organisms. In informal classification In addition to its use in ecology, the term "forb" may be used for subdividing popular guides to wildflowers, distinguishing them from other categories such as grasses, sedges, shrubs, and trees. Some examples of forbs are clovers, sunflowers, daylilie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wetland
A wetland is a distinct semi-aquatic ecosystem whose groundcovers are flooded or saturated in water, either permanently, for years or decades, or only seasonally. Flooding results in oxygen-poor ( anoxic) processes taking place, especially in the soils. Wetlands form a transitional zone between waterbodies and dry lands, and are different from other terrestrial or aquatic ecosystems due to their vegetation's roots having adapted to oxygen-poor waterlogged soils. They are considered among the most biologically diverse of all ecosystems, serving as habitats to a wide range of aquatic and semi-aquatic plants and animals, with often improved water quality due to plant removal of excess nutrients such as nitrates and phosphorus. Wetlands exist on every continent, except Antarctica. The water in wetlands is either freshwater, brackish or saltwater. The main types of wetland are defined based on the dominant plants and the source of the water. For example, ''marshes'' ar ...

Boreal Forest
Taiga or tayga ( ; , ), also known as boreal forest or snow forest, is a biome characterized by pinophyta, coniferous forests consisting mostly of pines, spruces, and larches. The taiga, or boreal forest, is 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 Hokkaido). The principal tree species, depending on the length of the growing season and summer temperatures, vary across the world. The taiga of North America is mostly spruce; Scandinavian and Finland, Finnish taiga consists of a mix of Norway spruce, spruce, pines and Betula, birch; Russian taiga has spruces, ...

Brainworm
''Parelaphostrongylus tenuis'' (also known as meningeal worm or brainworm) is a neurotropic nematode parasite common to white-tailed deer, ''Odocoileus virginianus'', which causes damage to the central nervous system. Moose (''Alces alces''), elk (''Cervus canadensis''), caribou (''Rangifer tarandus''), mule deer (''Odocoileus hemionus''), and others are also susceptible to the parasite, but are aberrant hosts and are infected in neurological instead of meningeal tissue. The frequency of infection in these species increases dramatically when their ranges overlap high densities of white-tailed deer. The lifecycle begins in infected meningeal tissues in the central nervous system (CNS) where adult brainworms lay eggs. The eggs are dislodged from the CNS and pass into the lungs, where they hatch. The larvae are then coughed up, swallowed, and proceed through the gastrointestinal tract. Snails and slugs then serve as intermediate hosts, which are later eaten by ungulates, allowing ...

Dermacentor Albipictus
''Dermacentor albipictus'', the winter tick, is a species of hard tick that parasitizes many different mammal species in North America. It is commonly associated with cervid species such as elk (''Cervus canadensis''), white-tailed deer (''Odocoileus virginianus''), mule deer (''O. hemionus'') and caribou (''Rangifer tarandus'') but is primarily known as a serious pest of moose (''Alces alces''). As early as 1909, Ernest Thompson Seton described the winter tick as a greater enemy of the moose than were "wolves, bears, and cougars." The tick can be found all across North America, and has a large geographic distribution. While it can be found in several different habitats, it is often located in areas with a presence of moose. Some evidence indicates that increasing populations of the winter tick may be responsible for a steep decline in the eastern moose population throughout the southern half of their range. In recent years, heavy infestations up to 75,000 ticks have been seen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reforestation
Reforestation is the practice of restoring previously existing forests and woodlands that have been destroyed or damaged. The prior forest destruction might have happened through deforestation, clearcutting or wildfires. Three important purposes of reforestation programs are for harvesting of wood, for climate change mitigation, and for ecosystem and habitat restoration purposes. One method of reforestation is to establish tree plantations, also called plantation forests. They cover about 131 million ha worldwide, which is 3% of the global forest area and 45% of the total area of planted forests. Globally, planted forests increased from 4.1% to 7.0% of the total forest area between 1990 and 2015. Plantation forests made up 280 million ha (hectare) in 2015, an increase of about 40 million ha in the previous ten years. Of the planted forests worldwide, 18% of that area consists of exotic or introduced species while the rest consist of species native to the country where they are ...

Elk Island National Park
Elk Island National Park is a National Parks of Canada, national park in Alberta, Canada, that played an important part in the conservation of the plains bison. The park is administered by the Parks Canada Agency. This "island of conservation" is east of Edmonton, along the Yellowhead Highway, which goes through the park. It is Canada's eighth smallest in area but largest fully enclosed national park, with an area of . The park is representative of the northern prairies plateau ecosystem and as such, the knob and kettle landscape is a mix of native fescue grassland that has been converted to forage land dominated by non-native grasses, aspen parkland and boreal forest. As well, Elk Island hosts both the largest and the smallest terrestrial mammals in North America, the wood bison and American Pygmy Shrew, pygmy shrew respectively. History Elk Island National Park is situated in the Beaver Hills (Alberta), Beaverhills area, which with its aspen thickets and easy access to w ...

Alberta
Alberta is a Provinces and territories of Canada, province in Canada. It is a part of Western Canada and is one of the three Canadian Prairies, prairie provinces. Alberta is bordered by British Columbia to its west, Saskatchewan to its east, the Northwest Territories to its north, and the U.S. state of Montana to its south. Alberta and Saskatchewan are the only two landlocked Canadian provinces. The eastern part of the province is occupied by the Great Plains, while the western part borders the Rocky Mountains. The province has a predominantly humid continental climate, continental climate, but seasonal temperatures tend to swing rapidly because it is so arid. Those swings are less pronounced in western Alberta because of its occasional Chinook winds. Alberta is the fourth largest province by area, at , and the fourth most populous, with 4,262,635 residents. Alberta's capital is Edmonton; its largest city is Calgary. The two cities are Alberta's largest Census geographic units ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
