Some years ago, when we lived in Wales, some local 'tree-huggers' decided they wanted to stop a planning application so they got hold of a 'footprint' of an otter, there was a stream running alongside the land subject to the planning applcation and they thought a few "otter prints" would stop the application.
They got away with it for some time until :
Someone pointed out that not only did the Otter have a 3 foot stride but it had 4 front feet and all of them were the front right foot.
We had a Badger sett on the farm and somehow the 'news' got out - we had an almost non-stop stream ,of trespassers breaking down the fences, we subsequently had horses get out and run free on the road because of it. After complainng to the Police it turned out that the local 'badger watch' had carte-blanche Government permission to access any land which was known to have Badgers on it - they visited the Sett every week to make sure we had not killed or dug the Badgers - they were the worst lot for breaking down the fences.
I respect the countryside, but it is better managed by the likes of Gamekeepers than it is by Tree-Huggers
