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 Phase 3 Forest Inventory Program commenced in 1970 and the initial data collection was completed in 1984 as per a 1966 federal-provincial task force recommendation that a provincial forest inventory should be completed before private company timber harvest quotas came up for renewal in 1986. The inventory was initiated by the Alberta Forestry, Lands and Wildlife Department and was intended to facilitate future forest management plans and the revision of annual allowable cuts. The extent of the Phase 3 Forest Inventory reflects the extent of Alberta's Green Area and fringe areas at that time minus three Forest Management Units in the north (A13, F10 and F20), the Cold Lake Air Weapons Range (L9), the Federal Indian Reserves and the Wilderness Areas. Under the Phase 3 Forest Inventory Program, the cover types were interpreted from aerial photography (mainly 1:15 000 black and white) to generate a hardcopy map base. These maps are not available as geo-referenced rectified images or...

Description

The Phase 1 (Broad Scale) Forest Inventory was initiated in 1949 and completed by 1956. The Phase 1 (Broad Scale) Forest Inventory included all publicly owned forested lands in the province except Indian lands, national parks, and an area known as the Rocky Mountains Forest Reserve. The Phase 1 (Broad Scale) Forest Inventory was used to define lands suitable for agriculture, to determine timber harvest levels and plan forest protection and timber and industrial development. Through aerial photo interpretation, land was classified as productive, potentially productive, or non-productive. On productive forest land, homogeneous groups of trees were classified by 'cover types'. Cover types included crown density, height and tree species. Burned, harvested or cultivated land was identified as potentially productive. Non-productive lands included areas with organic soils, barren rock and lakes. No ages or site classes are associated with the polygons. The minimum polygon size was 65 ha....

Description

The Phase 2, or Detailed, Forest Inventory is the second provincial level forest inventory conducted in the province of Alberta. The Phase 1 (Broad Scale) Forest Inventory (initiated in 1949 and completed by 1956) preceded the Detailed Inventory. The Phase 2 (Detailed) Forest Inventory was undertaken to cover lands where commercial timber commitments existed that were not inventoried as part of the Phase 1 (Broad Scale) Forest Inventory. The Phase 2 (Detailed) Forest Inventory utilized aerial photography from 1956 to 1966 to capture attribution similar to the Phase 1 (Broad Scale) Forest Inventory but at a more detailed level. A minimum stand size of 16.2 ha (40 acres) was used and the information was largely mapped at a scale of 1:31 680. Detailed information collected through the Phase 2 Inventory included species composition, stand density, stand heights, site class and the maturity or year of stand establishment. Cover type volume tables (CTVT) were developed, each applicable to...
