Description

The Peace River Parkland Natural Subregion accounts for only 0.5 per cent of the province and is characterized 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 378 plots described in the Peace River Parkland subregion. These 378 plots represent 73 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. Included in this approximation is a crosswalk table to the Alberta Wetland Classification System (AWCS) and a list of ecological sustainable stocking rates for each plant...

Ecological sites of the Dry Mixedwood subregion. Third approximation

The Dry and Central Mixedwood subregions cover nearly 40 per cent of the province and are dominated by aspen, with jack pine on coarse textured soils, and black spruce, willows, and sedges in the... More ≫

Description

The Dry and Central Mixedwood subregions cover nearly 40 per cent of the province and are dominated by aspen, with jack pine on coarse textured soils, and black spruce, willows, and sedges in the poorly drained areas. The vegetative communities in these subregions are important because they provide summer range for livestock, prime habitat for many species of wildlife, productive watersheds, recreational areas and timber production. As a result guides like this were developed to provide a framework that will easily group the vegetative community types. It is hoped these classification systems can be used by resource managers to assess the ecology of the sites and develop integrated management plans within each region. This guide represents the analysis of 1110 plots described within the Dry Mixedwood subregion. The dominant plant species, canopy cover, soils and environmental conditions are outlined for each type. Included in this approximation is a crosswalk table to the Alberta...

Ecological sites of the Subalpine subregion. Second approximation

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... 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 Upper Foothills Natural Subregion includes about 34 per cent of the Foothills Natural Region area. It occupies a narrow belt between the Lower Foothills Natural Subregion at lower elevations and the Subalpine Natural Subregion at higher elevations, with one outlier on the highest elevations of the Swan Hills. This guide represents the analysis of over 2250 plots described in the Upper Foothills subregion, representing 106 community types. The dominant plant species, canopy cover, environmental conditions and response to grazing are outlined for each type.

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.
