The District is working hard to save our Hemlock trees from the invasive species, Hemlock Woolly Adelgid (HWA). We hope this work will prevent the death of the trees and eliminate the need for any cutting and removal in the future — this is the risk if the pest is allowed to remain and trees are left untreated.
What is the Hemlock Woolly Adelgid (HWA) ?
Hemlock woolly adelgid is an aphid-like insect (aphids suck fluid from plants) that attacks and kills hemlock trees by feeding on nutrient and water storage cells at the base of needles. In Canada, eastern provinces are at-risk due to proximity to HWA populations in the states. In 2017, HWA was found and is now being closely monitored in the southwestern Nova Scotia counties of Digby, Queens, Shelburne, Yarmouth, Annapolis, and, most recently, Lunenburg in 2020.
What can I do to limit the spread of HWA?
- Wear clean footwear and clothes when going into forested areas.
- Clean campers, cars, and gear, including lint rolling and washing clothing when leaving potentially infested areas. This is especially important when travelling from Southwest Nova Scotia to other parts of the province or into other provinces.
- Do not collect or move materials from one site to another, including firewood.
- Do not transport lumber from potentially infested areas.
Are the pesticides being used safe for the public?
The pesticide being used is approved for use by Health Canada and is safe to use.
