Forest Health

The Manitoba government monitors for various forest pests and diseases, including spruce budworm, jack pine budworm, and Dutch elm disease along with invasive pests, such as emerald ash borer and gypsy moth. Monitoring is done through visual inspections and baited trapping of adult insects. In some cases, control programs are implemented to curb the spread and damage caused by some forest pests and diseases in the province.
