If, as the owner claims, they've been doing it for years, i don't quite see a problem. I'm just surprised that this bloke's wife who 'used to regularly jog around the forest' hasn't encountered one of these naturists before now. For all we and her husband know, she's chosen that place to go jogging (yes, that's a 'j') in the hope of spotting one or two?
And i know it's Sherwood but the naturists are not all men as the headline would have us believe. some are merry women :-)
