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...

The Boreal Subarctic Natural Subregion is found on elevated plateaus of far northern Alberta, and encompasses about three per cent of the Boreal Forest Natural Region. It is dominated by open... More ≫

Description

The Boreal Subarctic Natural Subregion is found on elevated plateaus of far northern Alberta, and encompasses about three per cent of the Boreal Forest Natural Region. It is dominated by open black spruce bogs and peatland complexes with frozen organic soils and permafrost terrain. This guide represents the analysis of 142 grass, shrubland, conifer and deciduous plots described in the Boreal Subarctic Natural Subregion. The 142 plots represent 53 community types within 11 ecological sites. 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 Wetland Classification System and new soil type descriptions.

Description

The second approximation of this guide represents the current analysis of 482 plots described in the Lower Boreal Highlands Natural Subregion. The boreal ecosection includes 227 plots that represent 37 plant community types and the foothills ecosection includes 255 plots that represent 47 plant community types. The dominant plant species, canopy cover, soil and environmental conditions are outlined for each plant community type, ecological site and ecological site phase. Included in this approximation is a crosswalk table to the Alberta Wetland Classification System and new soil type descriptions.

Description

Derived Ecosite Phase (DEP) is a digital and spatial representation of ecological sites and phases in those areas of Alberta where both Alberta Vegetation Inventory (AVI) and lidar are available. AVIE and a lidar-derived slope position were created by Agriculture and Forestry. Rules used to classify the data were developed by Environment and Parks. DEP v2.0 includes updated AVI, new lidar and an Alberta Wetlands Classification System field.

Method comparison and method calibration applicable to forest measurements and model predictions

Description

In forest mensuration, forest inventory and forest modeling, it is common to compare the agreement between two sets of quantitative measurements. One set could be from a commonly-accepted reference method, the other from a new or alternative method, device, or model. If the measurements are statistically the same or practically "close enough" to each other, the more complex, more destructive and/or costly method can be replaced by the simpler, less destructive and/or more efficient method. Traditional statistical approaches used for such comparisons based on bias, correlation coefficient, coefficient of determination and significance tests are inadequate and not really relevant for agreement analysis. Various agreement measures proposed for agreement analysis are also insufficient and not pertinent in many respects. An alternative approach based on the limits of agreement proposed by Bland and Altman (1986) is introduced and demonstrated in this study, along with the method...

Description

Highlights work done by the Alberta Phosphorus Watershed Project between 2013-2017. The purpose of the project was to determine if widespread adoption of agricultural beneficial management practices would improve water quality at the watershed scale, and to develop the Alberta Phosphorus Management Tool as a means to identify highest risks for phosphorous loss. Results are presented in a detailed technical science report and an overview and key findings fact sheet.
