Effect On Migratory Birds
And:
I'm not particularly surprised by this aspect of the ruling. Most ornithologists, when asked to rank causes behind the decline in NA bird populations over the past several decades, wouldn't even put wind farms on their top ten list. In fact, if people really wanted to make a difference re saving endangered bird species they'd kill their pet cat (in particular if its an outdoor cat); each of these vicious little bastards kill about as many birds per year as an average turbine, and they can't heat your house.
Bats
This was the most interesting aspect of the decision for me. As noted, "there is very little scientific research available on the impact of wind turbines on bats, partly because bats are extremely difficult to study." Some highlights of the testimony included:
And this, with respect to mitigating the effect of turbines:
In the end, the Tribunal concluded:
Monarch Butterflies
The project was to be located near Prince Edward Point National Wildlife Area, which is a International Monarch Butterfly Reserves. Concerns were raised that it would negatively impact Monarch populations. The Tribunal didn't buy it:
Similarly with the local plant life: the project would not cause “serious and irreversible harm”. I'm not going to excerpt that bit, because lets face it plants are boring.
And I'll don't think I'll excerpt the bits about
Blanding's Turtle either, even though these considerations finally put a stop to the project. Its important to note, however, that the presence of turbines was not itself an issue. Rather, the problem lay with a road network that would have been built in order to construct and maintain them. This network would have been smack dab in the middle of the turtle's habitat; the beasts would have been forced to cross these roads on multiple occasions and at multiple points during their life cycle. Since the network would have been publicly accessible, more ATV and other traffic would have been drawn to the area. Furthermore, available mitigation measures were judged ineffective. Nobody obeys road signs, for example. And culverts where the turtles might safely cross under the road depend on the species having crossing "hot spots"--preferred road crossing points--where these devices might be installed. Unfortunately, Blanding's Turtles do not use their habitat in the appropriate manner.
So there you have it. A win for the anti-windfarm faction, but really more bad than good news in the ruling. Claims re the negative health effects of turbines continue to gain no traction. The
recent study by
Nissenbaum, which garnered so much media attention, is referenced a whole one time in the ruling. In practical terms it has clearly had no effect on the debate. Furthermore, the judgement's position re IBA's suggests that turbines can probably operate safely within protected areas. That's a pretty important point going forward.
