We should be concerned about the Hemlock Wooly Adelgid as
well here in NC. As of 2001, there were at least 18 NC counties
(and one in SC) with known HWA infestations, including some in
the Piedmont (e.g Orange, Alamance, and Forsyth). This is an
increase from *six* known infestations in the prior two years. I
would hate to see them get into the really good Blackburnian spots
here, such as Trout Lake...but I fear it's only a matter of time, if
they're not there already.
The Forest Service has a page on the Hemlock Wooly Adelgid at:
http://www.fs.fed.us/na/morgantown/fhp/hwa/hwasite.html
I, for one, find our prospects for ever digging out from under all the
invasive species rather depressing...but I'll keep hoping all the
same.
Good birding all,
