Field Notes
Out and about looking for hemlocks and HWA in areas within 20 miles of the coast (see the Scientist Challenge: http://vitalsignsme.org/forum/hemlock-woolly-adelgid). I'm in a nice, seemingly young and healthy stand of hemlocks, white pines, oaks, and a fun hickory or two. This little forest feels remote, but is steps from homes and busy Route 9 in Cumberland center. It smells so good in here.
For my HWA sampling, I looked at 4 of the 10 hemlock trees I found. I checked the undersides of 5 branches on each tree for white woolly sacs (up to 1m from the tips to trunk). No adelgids here! Keep out.
Supporting Evidence
Do you see any white fluff on the undersides of these healthy green needles? I don't!
Another branch inspected. No sign of the adelgid.
All branches I checked looked similar to this. No white sacs or black pin point buggies.

Comments
Thanks!
It's good to know you are out there looking. One sign to look for this time of year is the settled nymphs at the bases of the needles. Sometimes we use this for confirmation when we see shreds of wool that don't scream "hemlock woolly adelgid."
