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...

Potential of rangelands to sequester carbon in Alberta

Description

Large amounts of organic carbon are present in Alberta rangelands. One hectare of rangeland contains 50-200 tonnes of carbon in soil organic matter, 2-10 tonnes carbon in plant biomass and 1-2... More ≫

Description

Large amounts of organic carbon are present in Alberta rangelands. One hectare of rangeland contains 50-200 tonnes of carbon in soil organic matter, 2-10 tonnes carbon in plant biomass and 1-2 tonnes carbon in litter. Total organic carbon levels in rangeland soils are considerably greater than the amount of carbon present in the atmosphere above these soils or exchanged with the atmosphere each year. Total organic carbon in the 7 million hectares of native pasture in Alberta is equivalent to about three times the current annual emissions of all greenhouse gases in Canada.
