Forest Health Conditions in Ontario, 2006

 

The Forest Health Monitoring Program in Ontario is a partnership between the Ontario Ministry of Natural Resources (MNR) and the Canadian Forest Service (CFS).

 

The program provides 6 MNR and 6 CFS field staff for regular forest health monitoring in 12 work areas covering the province of Ontario.

Forest health in Ontario has been monitored since the 1930s in partnership with the federal government. Until 1998, the field monitoring and reporting was conducted by the Canadian Forest Service or its predecessors. The province provided support in the form of advice, use of aircraft, land for field stations, funding for specific projects, and occasional assistance with surveys. Since 1998, the program has been conducted jointly by the Ministry of Natural Resources (MNR) and the Canadian Forest Service (CFS).

Under this partnership approach to forest health monitoring, the province is Forest divided into 12 work areas for which MNR and CFS each provide six field staff. Each technician does the work of both organizations. The overall health of the forest is monitored through systems of plots that address either specific problems, such as aspen decline and drought, or ecosystem health, such as that of spruce-fir forests.

Major factors affecting forest health are monitored each year. The annual monitoring detects, identifies, quantifies, assesses and reports on major forest disturbances.

Detection is typically done through reconnaissance work, such as aerial surveys, ground checks, and investigating reports from MNR staff, the forest industry, and the public.

Identification, although often performed on-site, is verified by specialists within the CFS.

Quantification involves mapping major disturbances from the air, and ground checks to collect samples, determine population density, and collect data on impacts on tree growth and mortality.

Assessment involves estimating impacts on forest values, such as wood supply, recreation and tourism; analysing historical trends; making forecasts of insect or disease incidences; and predicting the impact on forest values.

The results are reported informally through one-on-one contacts with forest resource managers. A number of formal reports prepared annually also address forest health, such as the Status of Factors Affecting Forest Health in Ontario, annual Regional Forest Health Reports and the Annual Forest Health Review. In addition, staff make presentations at various meetings, workshops and conferences.

The reports are complemented by annual estimates of the amount of wood volume lost to insects, disease, and abiotic factors. Volume losses are calculated based on field assessments or data contained in scientific literature.
