    Human Activities in Ecosystems - Mining Sites

    In Canada, mines are most heavily concentrated in the Mixedwood Plains, Boreal Shield, Prairie, and Montane Cordillera ecozones. Mines require accessibility, and are therefore strongly correlated with transportation routes. While most mines are designed as closed systems, occasionally water...

    Percentage of Ecoregion Protected

    Protected areas are defined as legally established areas, both land and water, that are regulated and managed for conservation objectives. They include parks, wildlife and forest reserves, wilderness and other areas designated through federal, provincial, and territorial legislations. While there...

    Ecosystem Components: Wetland Diversity

    Wetlands are lands where water saturation is the dominant factor. Wetlands occupy about 18% of Canada, and Canada has about 25% of the world’s wetlands. Wetlands foster the growth of hydrophytic vegetation and other biological activities such as the sustenance of large numbers of waterfowl,...

    Ecosystem Components - Endemic Plant Diversity

    Endemic plants are those plants found only in Canada. These plants have genetically adapted to these particular environmental conditions. Because these are found nowhere else, Canada has a special obligation to ensure these plants do not become extinct. The map shows the number of endemic plants...

    Ecosystem Components: Land Cover Diversity

    Ecoregions vary in their make up and complexity. Some are relatively uniform in their composition, structure and processes. Others contain extreme variations in relief, soils, climate, vegetation, and species. This map shows the number of land cover types (up to 29 types are possible) per...

    Threats to Ecosystems - Population Variation by Ecoprovince, 1971 to 1996

    The higher the concentration of people in an ecoprovince, the higher the chance of loss of habitat and species. To better evaluate and minimize population impacts on the environment, it is necessary to study the distribution and variation of population within ecological areas. The map shows the...

    Human Activities in Ecosystems - Productive Forest Land Use

    Forests sustain hundreds of economies across Canada. The forest industry is an active player in the conservation and sustainability of forested ecosystems. Forests are managed from a legal perspective by provincial and territorial legislation. The primary objective of forest management is timber...

    Threats to Ecosystems - Road Density

    Transportation activities have a great impact on the environment because they fracture natural habitats and create pollution. Roads intrude into natural habitats, separating ecosystems and permanently altering the landscape. Road building has undesirable effects on species that require large...

    Threats to Ecosystems - Industrial Discharge Sites

    Industrial activities generate waste that is discharged into water bodies, the air or ends up in landfill sites. Air is the most common release medium. Ammonia, methanol, sulfur dioxide, and nitrogen dioxide are by far the most common industrial pollutants released in Canada. Industrial discharge...

    Ecosystem Components - Rare Plant Diversity

    Some plants are rare because they naturally occur in very specialized habitats or in very low numbers; others may be rare because they have suffered setbacks because of natural processes or pressures from human activities. The highest number of rare plant species is in southern Ontario, where...
