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.
Treatments for the most recent season (2020)
In 2020, a total of 35,000 hectares of forest was treated with Bacillus thuringiensis (Bt) and Tebufenozide. This was an increase from 25,000 hectares in 2019. For the most up-to-date information, go to the map section of the Healthy Forest Partnership website.
