Description

Extended periods of extreme cold (below -38°C) can cause up to 95 per cent mortality of over-wintering mountain pine beetles, which is required to suppress populations. These maps display predicted per cent mortality, based on a mountain pine beetle overwinter mortality model used by the province to predict per cent mortality based on winter temperatures and location data. These mortality predictions, combined with aerial surveys and ground assessments conducted in August/September, help the province prioritize areas for single tree treatment and timber harvest control tactics implemented in the fall and winter.

Description

To ensure sustainable management of our forest ecosystems, Alberta Forestry Division maintains a network of permanent sample plots (PSPs) across the forested regions of the province. The growth of a stand can be estimated directly by taking measurements of the same trees at periodic intervals. These plots provide a steady flow of measurement data to document forest growth and health over the long-term. PSP data support growth and yield modeling, inventory calibration, determination of the sustainable timber supply, stewardship reporting, and are a source of forest dynamics data sought by research organizations for innovation in forest monitoring and modeling.
