The red colored regions indicate identified hemlock stands, although, as seen in the map, we sampled some in surrounding areas and found some individual hemlock trees. The smallest dots mapped on the stand represent hemlock stands sampled where adelgid was not present.
The blue stars represent the actual locations of CFI points we were able to discover. According to our GPS measurements CFI point 169 in Stand 1, which was supposed to be located at longitude -72.3892, latitude 42.255, was located according to our measurements at latitude-72.2337 and 42.2731 or longitude-72.389318, lattitude 42.412103. CFI point 171 was supposed to be located at longitude -72.389, latitude 42.4626. but we found it at longitude -72.389407, latitude 42.462193 or longitude -72.38947, latitude 42.462232. In Stand 2, CFI point 151 was supposed to be at longitude 72.3991 and latitude 42.412, but we marked it at longitude 72.399052, latitude 42.412103. CFI point 153 which was supposed to be located at longitude -71.3794, latitude 42.4119 was actually located at longitude 72.38, latitude 42.4119.
In the first stand, we discovered no adelgid infestation in the northern portion of the stand, but in the southern portion of the we found a mild infestation, once we moved away from the road and the river. Both canopy and understory trees were infested. Although, the northern portion of the stand seems relatively unaffected, the presence of adelgid in the southern region indicates a likelihood of the adelgid spreading to the northern region and fully infesting the entire stand. The trees of the
We discovered adelgid in most of the trees sampled in the second stand. There were patches where the infestation was less widespread, particularly near CFI point 153, however overall our evalutation shows that adelgid are present throughout the stand.
