I would be interested to see the research on lynx habitat permanently impacted by windfarms. I have seen prior references that the resurgence of Lynx in Maine was aided by clear cutting as it improved the snowshoe hare habitat, but cant cite any specific studies.
When the spotted owl became the symbol against cutting trees in the NW there was an attempt by regional groups to identify the "spotted owl of the east", initially Pine martens were identified, but subsequently rejected as there were studies in place that they like regnerated softwood stands. The next candidate was the Lynx but I believe they too were established to prefer regrowing clear cuts. Although it doesnt impact western Maine significantly, I think the Atlantic Salmon listing trumped the effort.
I expect there was an impact during construction, but once the turbines are in operation it would be hard to imagine that the wildlife in the area would not become tolerant.
Granted it does subjectively despoil an area from a distance but given its past as a working forest (a good way to get a view of its recent history is to use the history function on Google Earth), it has not been pristine forest in a long time.
With regard to access to the area, I am not sure of the current status. They had indicated that access would be limited during construction but their project manager had stated publicly that the area would be reopened to the public after constuction. Do note that they dont own the surrounding land and the current owner, John Mallone's firm, could elect to keep the gates locked.
