This industry has been well aware of the problems directly caused by wind turbine noise since 1987, when Dr Neil Kelley's research [12] establishing direct causation of annoyance symptoms from infrasound and low frequency noise was presented at the American Wind Energy Association conference.

The consequences of exposure to impulsive infrasound and low frequency noise generated by wind turbines were also clearly well known to the global wind industry, because of the dramatic change in design which resulted, and because the results were presented at the AWEA sponsored conference.

At present, the northernmost woodlands and krummholz are less susceptible to burning and being destroyed by fire owing to the still cool and humid climatic conditions prevailing in the northern part of the forest tundra, where fire frequency is very low, and the lack of extensive forest fuels.
