WWF Terrestrial Ecoregions Collection
The Alberta Mountain forests ecoregion lies entirely within Canada and almost fully within the province of Alberta, but hugs the Alberta-British Columbia border from Banff northward to Jasper and Kakwa. The ecoregion is classified within the Temperate Coniferous Forests biome.
Mean annual temperature in the Eastern Continental Ranges is 2.5°C, mean summer temperature is 12°C and mean winter temperature is -7.5°C. Precipitation increases from east to west and also with elevation, from 600-800 millimetres (mm) per year. Valley regions are marked by warm, dry summers and mild, snowy winters, and subalpine areas have cool, showery summers and cold, snowy winters.
This region covers the Rocky Mountains of Alberta, incorporating the eastern flanks of the Continental Ranges. The major peaks cluster... More »
Canadian Rocky Mountain Parks, CanadaLast Updated on 2014-12-08 19:23:12The contiguous national parks of Banff, Jasper, Kootenay and Yoho, with the adjoining Mount Robson, Hamber and Mount Assiniboine provincial parks (50°34'-53°28'N, 115°10'-119°32'W), are World Heritage Sites located at the continental divide of the central Rocky Mountains at their highest point. They protect an approximate linear extent of 400 kilometres (km) of forested mountain landscape studded with dramatic peaks, glaciers, lakes, cascades, canyons and limestone caves,. The Burgess Shale fossil site, inscribed as a World Heritage site in 1980 and noted for its fossil remains of soft-bodied marine fauna, is within Yoho National Park.
The parks are a 400 km long continuous belt of protected areas bestriding the central Rocky Mountains at their highest, along the British Columbia-Alberta border. The ridge axis extends from north to south: Jasper... More »
OverfishingLast Updated on 2014-12-07 17:22:32Overfishing is the human act of extracting aquatic (that is, marine and freshwater) fauna from natural water bodies at a rate greater than the reproductive and recruitment functions can replace that extraction. While there is some evidence that localized overfishing may have occurred in prehistoric eras, the bulk of overfishing has taken place in the last 150 years as the human population has expanded greatly and fishing technologies have enabled harvesting of many species at rates not imagined in earlier times. For over a century man's role in the depletion of certain regional fisheries has been noted. A functional definition of overfishing is sometimes given as the reduction in catch per unit effort by fishermen. Typically the concept of overfishing is linked to an individual aquatic species, and this issue is most often discussed within a specific marine or lacustrine province... More »

Comoé National Park, Côte d'IvoireLast Updated on 2014-07-09 15:50:49
Comoé National Park (8°32' - 9°32'N, 3°01' - 4°24'W) is a World Heritage Site. One of the largest protected areas in West Africa, this park is characterized by its great plant diversity. Due to the presence of the Comoé river, it contains plants which are normally only found much farther south, such as shrub savannas and patches of thick rainforest.
The present unrest in Côte d'Ivoire is having an adverse effect on the site, as is poaching of wildlife and fires caused by poachers, over-grazing by large cattle herds and the absence of effective management.
Located in the far northeast of the country south of the border with Burkino Faso between the towns of Bouna and Kong, 350-450 kilometers (km) north of Abidjan: 8°32' - 9°32'N, 3°01' - 4°24'W.
