Description

Aerial overview surveys are carried out by observers in fixed-wing aircraft flying at appropriate safe heights above ground level over the forest canopy. Surveys cover extensive areas to detect as many new FHDA-caused disturbances as possible. Surveyors record locations, extent, severity, possible causative agent and host tree species involved in the disturbances. Aerial surveys are cost-effective means of obtaining forest health damaging agent (FHDA) caused disturbance data at the landscape level. These surveys help to manage forests by providing early detection of FHDAs and once detected, by monitoring their trends. Aerial surveys are carried out to record locations, extent and severity of new, FHDA-caused disturbances. changes to known FHDA disturbances for historical and evaluation purposes. background information needed for planning management actions. and, forest health data at the forest area, regional and provincial levels for reporting and inventory update. This dataset...

Mountain Pine Beetle Inventory 2011 - Current

Description

The mountain pine beetle (Dendroctonus ponderosae Hopkins, MPB) is native to western Canada. It attacks all pine including lodgepole, limber, whitebark and jack pine. Over the past 40 years the... More ≫

Description

The mountain pine beetle (Dendroctonus ponderosae Hopkins, MPB) is native to western Canada. It attacks all pine including lodgepole, limber, whitebark and jack pine. Over the past 40 years the range of mountain pine beetle has expanded, possibly due to changes in the area of climatically suitable habitat. Known Limitations: The areas surveyed each year can be different and therefore year over year comparisons may be difficult. the surveyors do not do ground truthing for all disturbances identified, therefore it is not guaranteed that all of the disturbances are caused by MPB. the surveyors do not necessarily map tree patches less than three red trees and therefore the dataset may not include all MPB killed trees. 'grey' attacked trees are not captured. the surveyors attempt to distinguish between 'new' faders and 'old' faders but the accuracy of this distinction is not guaranteed and therefore the data may reflect several years and several generations of MPB attack. Beetle year is...

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...
