Experts warn public about invasive tree-killing insect found in N.S.
“HWA, also known as hemlock woolly adelgid, is a small insect pest of hemlock species in North America,” said Natural Resources Canada research scientist, Lucas Roscoe. “It’s originally from Japan and is considered an invasive species in the eastern United States.”
The insect, which causes serious damage to hemlock trees, was first discovered in N.S. in 2017. The arrival of the species causes great concerns due to the rich Acadian forests in the province.
