As climate change brings warmer winters, our forests face a higher risk of pests. One is the Hemlock Woolly Adelgid (HWA), a small insect native to East Asia. The pest arrived in Eastern Canada in the early 2010s, reaching Nova Scotia as it moved north from the eastern United States.
HWA spreads in several ways, including wildlife migration (attaching itself to fur), wind, and transporting firewood from infested forests, to name a few. Warmer winters also increase the pest's survival rate.
Fortunately, the HWA has not been found in New Brunswick. But our team knows the question is not whether the pest will arrive in NB, but when. Right now, Nova Scotia is dealing with the devastating impacts of the HWA, and our team has supported some of those efforts while learning a lot from the methods being implemented in the province.
One of the first properties we acquired, and therefore a very sentimental place, is Whaelghinbran Forest. Within this forest, there is a special 13-hectare eastern hemlock stand. Composed of about 95% hemlock trees, the stand is highly vulnerable to the HWA. For a few years now, our Forest team has been working on a plan to increase this stand's resilience to the pest we know will come.
We are doing this by harvesting some hemlock trees and freeing up space for other desirable tree species to grow, like white pine and red oak. These species will grow into healthy trees that can continue to absorb and store carbon. Once the pest hits the hemlock trees, we will have more time to address the pest itself while reducing rapid mortality in a 13 ha stand and the resulting considerable release of carbon. The intervention we are implementing was no easy decision. Still, based on our experience so far and consulting with different partners, we believe this is the best way to increase the hemlock stand's resilience to the Hemlock Woolly Adelgid.
