Hemlock Wooly Adelgid

I have no idea if there's any similar hope that the same may be true of EAB, but I have personal hope, at least. And of course, with climate change, who knows whether future winters will be a limiting factor for the adelgid, either.

I think from what I can remember from a Cornell Forest Connect, HWA is already here in NY.

I don't know off the top of my head exactly why, but I recall it's not very severe... yet. I do recall the Adelgid having a crazy life cycle and that it was being studied intensely at Cornell to try to limit spread or infestation here.

I'd be devastated if it took out the Adirondacks. I seem to recall a number of older, large Hemlocks, mostly around lakes and ponds, that would be terrible to lose.

And I think the issue around here is that they generally grow, or can really only compete along seasonal streams and glens, where apparently they lower the temperature of the water. I'd assume that's where the impact to the fish could be substantial.

I'd assume, from pics I've seen of PA's creeks and glens, they'd have the same issue. Looks exactly like southern FLR.
