Ecological sites of the Subalpine subregion. Second approximation

The Subalpine Natural Subregion is a Rocky Mountain altitudinal vegetation zone extending from an elevation of 1575 m to 2175 m at its southernmost occurrence and 1365 m to 2000 m near Grande... More ≫

Description

The Subalpine Natural Subregion is a Rocky Mountain altitudinal vegetation zone extending from an elevation of 1575 m to 2175 m at its southernmost occurrence and 1365 m to 2000 m near Grande Cache. This approximation of the guide represents the analysis of over 3400 plots described in the Subalpine subregion. In this subregion it was found there were distinct differences between the community types and ecological sites between the Central and Northern Foothills and Mountains (west of Sundre, Hinton, Grande Cache and Jasper national park), and the Southern Rocky Mountains (south and west of Calgary and Banff national park). As a result the Subalpine plant communities are identified into two ecosections (south and north). The dominant plant species, canopy cover, environmental conditions and response to grazing, are outlined for each plant community type for each ecosection.

Description

The Lower Foothills Natural Subregion occupies a broad northwest-to-southeast belt between the Bow River Valley to the south and Grande Prairie to the north, with outliers in the Swan Hills and Pelican Mountains to the east, and the Saddle Hills to the north. This guide represents the analysis of 2082 plots described in the Lower Foothills subregion, representing 116 community types. These community types were described in 15 ecological sites. The various community types fit within these broad categories of disturbed and undisturbed forested and non-forested types.

Description

The Peace River Parkland Natural Subregion accounts for only 0.5 percent of the province and is characterised by gently rolling cultivated plains and steep south-facing grassy and forested slopes along the Peace River and its tributaries. Vegetation is a mosaic and dominated by forests of aspen and white spruce, wetlands and small remnant grasslands on the uplands, and dry grasslands and aspen forests on valley slopes. This guide represents the analysis of 345 plots described in the Peace River Parkland subregion. These 345 plots represent 70 observed and described plant community types. An analysis of successional changes in the presence and absence of grazing disturbance for the grasslands (Appendix 1) and aspen (Appendix 2) dominated community types for the Peace region is also outlined in Appendices 1 and 2.

The purpose of this guide was to develop a framework that would easily group the ecological sites and vegetative community types in the Dry Mixedwood Natural Subregion of the province. Ecological... More ≫

Description

The purpose of this guide was to develop a framework that would easily group the ecological sites and vegetative community types in the Dry Mixedwood Natural Subregion of the province. Ecological site classification helps to organize our current understanding about ecosystem function. This organization is achieved by grouping research plots into similar and functional units that respond to disturbance in a similar and predictable manner.The ecological site classification system outlined in this document organizes ecological information into a format that facilitates understanding and provides a structure for ecologically based management. The system has been developed primarily as a field tool to complement the user's knowledge about ecological site classification, soil description, and plant identification.

Description

The Lower Foothills subregion is a classic example of multiple use land. The land provides summer range for livestock, primary habitat for wildlife, productive watersheds, timber and recreational areas. The purpose of this guide was to develop a framework that would easily group the ecological sites and vegetative community types in the subregion. This guide represents the analysis of 1,950 plots representing 115 community types. The dominant plant species, canopy cover and environmental conditions are outlined for each type.

Description

The province of Alberta is covered by a broad spectrum of vegetation regions and have been classified into 6 natural regions and 21 subregions for the province (Natural Regions and Subregions of Alberta 2006). Each of the regions consists of groups of plant communities which are influenced by environmental conditions and human impacts. This guide represents the preliminary analysis of 129 plots described in the Athabasca Plain subregion. The 129 plots represent 36 plant community types. The dominant plant species, canopy cover, soil and environmental conditions are outlined for each plant community type.
