The Pest Decision-Support Systems Group
- Spruce budworm outbreaks are natural disturbances that cause
significant growth loss and mortality in spruce-fir forests in
eastern Canada. This results in large uncertainty about future
forest structure and productivity.
- The Canadian Forest Service has built upon the results of scientific
research studies about spruce budworm impact to develop the Spruce
Budworm Decision Support System (SBWDSS).
- A major component of SBWDSS is the Protection Planning System
(PROPS), which integrates a geographic information system (GIS),
a stand growth and yield model, and a forest-planning model.
- PROPS determines the marginal timber supply benefits (m3/ha)
and forest structure consequences of alternative management actions,
and facilitates incorporating the effects of insect damage into
forest management planning.
- Spatial data representing forest inventory, historical budworm
defoliation, predicted defoliation, and future harvest plans are
used, along with nonspatial forest management information.
- The SBWDSS is being implemented throughout New Brunswick and
in parts of Quebec, Saskatchewan, Ontario and Alberta.
