New Brunswick organizations leading the monitoring, detection and application of treatments

The monitoring, detection and application of treatments is conducted using a collaborative approach through the Healthy Forest Partnership. The monitoring (branch sampling for overwintering larvae (L2)) and pheromone traps (male moths) is carried out by the Federal and Provincial Governments and the forest industry. The samples, are analyzed in laboratories located at the Canadian Forest Service and the New Brunswick Department of Energy and Resource Development.

In addition to populations sampling, the New Brunswick Department of Energy and Resource Development conducts aerial surveys for defoliation in late summer. The populations surveys and defoliations surveys are available on the Healthy Forest Partnership website.

Planning for treatments is based on the results of population and defoliation surveys. The treatments are collaboratively planned by the research team, government partners and Forest Protection Limited.  Communication support is provided by the Healthy Forest Partnership communication committee.
