It's always been my understanding that HWA killed what was often referred to
as NYC's only old growth forest. I moved to NYC in the late 70s and no one
thought hemlocks were in any danger of dying. No one knew then that HWA was
coming to wipe out our hemlocks throughout the region. But HWA can kill
really fast. I've seen forest patches in this region decimated within
5-years of infestation. The trees become totally moth-eaten and awful
looking, but I don't have to tell you that. When we moved from NYC to
Hastings in Westchester County in 1992, the first thing we had to do was cut
down three 50-70 ft dying hemlocks. We managed to save one that is now
maybe 70 ft tall. Basically, already by the early 90s, the only live healthy
hemlocks were yard trees and hedges that were being sprayed regularly by
tree care services.
