20210626 01094300 1.0 TRUE TRUE Mountain pine beetle operations 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 (killed this year by MPB) and therefore the dataset may not include all MPB killed trees; "grey" (old) 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 August 15 of current year - August 14 of following year.Contact: for-info@gov.ab.ca Inventory of mountain pine beetle (MPB) attacks on all pine including lodgepole, limber, whitebark and jack pine in Alberta. The purpose of the point-level helicopter surveys is to detect locations of current MPB activity to inform management decisions.
