Often it's not the wind farm that causes the trouble but the extremely difficult to see anemometer masts that are erected all over the place while they try to establish where best to site the turbines. More often than not these masts do not require to be pre notified or NOTAM'd, are temporary in nature and are at heights that could make your eyes water!
Many FW and RW aircraft operating in the low level environment have had very late spots and I believe many mil flying units now maintain their own charts depicting these obstructions...once spotted.
