I doubt they were involved in any way, but see:

If the Woodlands Trust advises people on how to object to planning applications, that could cost some companies a lot of money, and cause them lots of problems. Details of WT membership might indicate where objections to plans are likely to be raised and by whom. I suspect there may be unscrupulous people out there who would like to be forewarned of such possible adversaries.
