Ecosection

Last updated

An ecosection is a biogeographic unit smaller than an ecoregion that contains minor physiographic, macroclimatic or oceanographic variations. They are a virtual ecological zone in the Canadian province of British Columbia, which contains 139 ecosections that vary from pure terrestrial units to pure marine units. [1]

Ecoregion Ecologically and geographically defined area that is smaller than a bioregion

An ecoregion or ecozone is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation.

Ecological classification or Ecological typology is the classification of land or water into geographical units that represent variation in one or more ecological features. Traditional approaches focus on geology, topography, biogeography, soils, vegetation, climate conditions, living species, habitats, water resources, and sometimes also anthropic factors. Most approaches pursue the cartographical delineation or regionalisation of distinct areas for mapping and planning.

Ecology of California

The ecology of California can be understood by dividing the state into a number of ecoregions, which contain distinct ecological communities of plants and animals in a contiguous region. The ecoregions of California can be grouped into four major groups: desert ecoregions, Mediterranean ecoregions, forested mountains, and coastal forests.

Aspen parkland Temperate grasslands, savannas, and shrublands ecoregion of Canada and the United States

Aspen parkland refers to a very large area of transitional biome between prairie and boreal forest in two sections, namely the Peace River Country of northwestern Alberta crossing the border into British Columbia, and a much larger area stretching from central Alberta, all across central Saskatchewan to south central Manitoba and continuing into small parts of the US states of Minnesota and North Dakota. Aspen parkland consists of groves of aspen poplars and spruce interspersed with areas of prairie grasslands, also intersected by large stream and river valleys lined with aspen-spruce forests and dense shrubbery. This is the largest boreal-grassland transition zone in the world and is a zone of constant competition and tension as prairie and woodlands struggle to overtake each other within the parkland.

Peace River Regional District Regional district in British Columbia, Canada

The Peace River Regional District is a regional district in northeastern British Columbia, Canada. The regional district comprises seven municipalities and four electoral areas. Its member municipalities are the cities of Fort St. John and Dawson Creek, the district municipalities of Tumbler Ridge, Chetwynd, Taylor, and Hudson's Hope, and the village of Pouce Coupe. The district's administrative offices are in Dawson Creek.

Shrub–steppe

Shrub-steppe is a type of low-rainfall natural grassland. While arid, shrub-steppes have sufficient moisture to support a cover of perennial grasses or shrubs, a feature which distinguishes them from deserts.

Butler Ridge Provincial Park

Butler Ridge Provincial Park is a provincial park in British Columbia, Canada. Located on the northern shore of the Peach Reach arm of Williston Lake, 20 km northwest of Hudson's Hope, the park covers an area of 6,694 ha. Within the Peace Foothills ecosection, it includes three biogeoclimatic zones: the Engelmann Spruce-Subalpine Fir, the Sub-Boreal Spruce, and the Black and White Boreal Spruce zones. This cold and moist area is used as winter ranges by caribou, Stone's sheep, moose, and elk. It is recognized by the province and the Treaty 8 Tribal Association as an area that has traditionally been used by First Nations people. The park is used for fishing, hunting, trapping, hiking, and wildlife/nature viewing, cross-country skiing. There is a boat launch for Williston Lake, and motorized recreation.

One Island Lake Provincial Park

One Island Lake Provincial Park is a provincial park in British Columbia, Canada.

Union Passage Marine Provincial Park

Union Passage Marine Provincial Park is a provincial park within the asserted traditional territory of the Tsimshian First Nations. The marine protected area is located at the southwest end of Grenville Channel straddling Pitt and Farrant Islands, in British Columbia, Canada.

The Lower Mainland Ecoregion is the biogeoclimatic region that surrounds Vancouver, British Columbia, comprising the eastern edge of the Georgia Depression and extending from Powell River, British Columbia on the Sunshine Coast to Hope at the eastern end of the Fraser Valley. It thus corresponds, for the most part, with the popular usage of the term "Lower Mainland." The Lower Mainland Ecoregion is a part of the Pacific Maritime Ecozone.

An ecoprovince is a biogeographic unit smaller than an ecozone that contains one or more ecoregions. According to Demarchi (1996), an ecoprovince encompasses areas of uniform climate, geological history and physiography. Their size and broad internal uniformity make them ideal units for the implementation of natural resource policies.

Hoodoo Mountain Stratovolcano in British Columbia, Canada

Hoodoo Mountain, less commonly called Hoodoo Volcano, is a potentially active stratovolcano in the Northern Interior of British Columbia, Canada. It is located 25 kilometres northeast of the Alaska–British Columbia border on the north side of the Iskut River opposite of the mouth of the Craig River. With a summit elevation of 1,850 metres and a topographic prominence of 900 metres , Hoodoo Mountain is one of many prominent peaks within the Boundary Ranges of the Coast Mountains. Its flat-topped summit is covered by an ice cap more than 100 metres thick and at least 3 kilometres in diameter. Two valley glaciers surrounding the northwestern and northeastern sides of the mountain have retreated significantly over the last hundred years. They both originate from a large icefield to the north and are the sources of two meltwater streams. These streams flow along the western and eastern sides of the volcano before draining into the Iskut River.

Cascadia (bioregion)

The concept of Cascadian bioregionalism is closely identified with the environmental movement. In the early 1970s, the contemporary vision of bioregionalism began to be formed through collaboration between natural scientists, social and environmental activists, artists and writers, community leaders, and back-to-the-landers who worked directly with natural resources. A bioregion is defined in terms of the unique overall pattern of natural characteristics that are found in a specific place. The main features are generally obvious throughout a continuous geographic terrain and include a particular climate, local aspects of seasons, landforms, watersheds, soils, and native plants and animals. People are also counted as an integral aspect of a locale's life, as can be seen in the ecologically adaptive cultures of early inhabitants, and in the activities of present-day reinhabitants who attempt to harmonize in a sustainable way with the place where they live.

Level Mountain Volcanic complex in British Columbia, Canada

Level Mountain is a large volcanic complex in the Northern Interior of British Columbia, Canada. It is located 50 kilometres north-northwest of Telegraph Creek and 60 kilometres west of Dease Lake on the Nahlin Plateau. With a maximum elevation of 2,164 metres , it is the second-highest of four large complexes in an extensive north–south trending volcanic region. Much of the mountain is gently-sloping; when measured from its base, Level Mountain is about 1,100 metres tall, slightly taller than its neighbour to the northwest, Heart Peaks. The lower, broader half of Level Mountain consists of a shield-like structure while its upper half has a more steep, jagged profile. Its broad summit is dominated by the Level Mountain Range, a small mountain range with prominent peaks cut by deep valleys. These valleys serve as a radial drainage for several small streams that flow from the mountain. Meszah Peak is the only named peak in the Level Mountain Range.

Okanagan Desert

The Okanagan Desert is the common name for a semi-arid shrubland located in the southern region of the Okanagan Valley in British Columbia and Washington. It is centred around the city of Osoyoos and is the only semi-arid shrubland in Canada. Part of this ecosystem is referred to as the Nk'mip Desert by the Osoyoos Indian Band, though it is identical to the shrublands elsewhere in the region. To the northwest of this area lies an arid shrubland near Kamloops.

Montane Cordillera

The Montane Cordillera Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is an ecozone in south-central British Columbia and southwestern Alberta, Canada. A rugged and mountainous ecozone spanning 473,000 square kilometres, it still contains "two of the few significant agricultural areas of the province", the Creston Valley and the Okanagan Valley. Primarily a mountainous region, it consists of rugged ecosystems such as alpine tundra, dry sagebrush and dense conifer forests. The interior plains are encircled by a ring of mountains. The area has a mild climate throughout the year, with typically dry summers and wet winters.

Boreal Plains Ecozone (CEC) An ecozone

The Boreal Plains Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a terrestrial ecozone in the western Canadian provinces of Manitoba, Saskatchewan and Alberta. It also has minor extensions into northeastern British Columbia and south-central Northwest Territories. The region extends over 779,471 km2, of which 58,981 km2 is conserved.

Pacific Maritime Ecozone (CEC)

The Pacific Maritime Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a Canadian terrestrial ecozone, spanning a strip approximately 200 kilometres wide along the British Columbia Coast, then narrowing along the border with Alaska. It also includes all marine islands of British Columbia and a small portion of the southwestern corner of the Yukon. Fourteen ecoregions comprise the Ecozone, ranging from the Mount Logan Ecoregion in the north to the Cascade Ecoregion and Lower Mainland Ecoregion in the south.

Alberta–British Columbia foothills forests Temperate coniferous forests ecoregion of Alberta and British Columbia, Canada

The Alberta–British Columbia foothills forests are a temperate coniferous forests ecoregion of Western Canada, as defined by the World Wildlife Fund (WWF) categorization system. This ecoregion borders Canada's taiga and contains a mix of subarctic forest and temperate forest species as a result. This makes the region an ecotone region, or a region that acts as a buffer between two other biomes.

Okanagan dry forests Temperate coniferous forest ecoregion in British Columbia, Canada and Washington, United States

Okanagan dry forests is a temperate coniferous forest ecoregion in the Pacific Northwest of North America, as defined by the World Wildlife Fund (WWF) categorization system. It is closely associated with the Okanagan region of British Columbia and Washington. Only 20% of the ecosystem is still intact, and continues to be under threat for preservation due to land clearing and urban expansion, alongside the increasing threats of fire and extreme weather due to climate change.
