Old Growth Cumulative Effects Reporting

To support decision-making in the management of B.C.s forests, the Province is producing reports on the current condition of old growth forests and forest biodiversity throughout B.C. These reports contribute to public reporting on old growth recommended by the Old Growth Strategic Review Panel.

These reports are produced under the Cumulative Effects Framework (CEF). The Cumulative Effects Framework helps B.C. measure the effects of human activities and natural processes on forests, wildlife species, and aquatic ecosystems, as part of its commitment to sustainable resource management.

Learn more about the strategic review's 5th recommendation in relation to better public data.

​Old Growth and Forest Biodiversity Current Condition Reports

Old Growth Current Condition Reports identify:

• The amount of old forest or old and mature forest in an area (e.g., natural resource district, timber supply area or strategic plan area), and how this compares to established legal and policy targets for that area
• The amount of old forest in defined old growth management areas (OGMAs)
• The amount of human disturbance in OGMAs, relative to established legal or policy limits

Forest Biodiversity Current Condition Reports estimate:

• The effects of landscape change on biodiversity by comparing current to historic forest conditions. Conditions examined include the amount of different forest age classes (young, mature, old) distributed across the landscape, habitat connectivity, and how habitat alteration affects wildlife behaviour, biology and interactions.

Together, the Old Growth and Forest Biodiversity Current Condition Reports provide a comprehensive overview of the condition of biodiversity on forested landscapes and our management relative to policy and legal direction. Until recently, these reports have been prepared separately, but going forward they will be published concurrently to provide an ecologically-based picture of the state of biodiversity and distribution of forest ages in the context of current approaches to management.

Reports underway and completed

In addition to the reports outlined below, reports for other areas of the province are planned and details will be added when available.

Reports will be made available on the old growth forest value page or the forest biodiversity value page when complete.
