Are there any rules that I need to know about with regard to the number of trees you can cut down in a given year? (assuming you've not in any SFP scheme or the like) and are the limits based on a % of your total acreage or anything like that?
Wales appears to have gone absolutely mad with what you can and can't do on your own land . Any oak is automatically protected , if you are in an SSI , a national park , a place that the RSPCA , RSPB or any other busybody who has registered ( usually unknown to you ) an interest in your land or if you live in or close to area of so called outstanding beauty you might come unstuck.
Most of the council & county councils have a lot of such info on their websites so if you borrow someone else's computer , you should be able to have a good look for such things and not have it tied to your name or email address .
I pretty certain that I've read something fairly recently that reported someone got slapped for several thousands of pounds for each tree they cut down tree plus a fine as well . I can't remember if it was done without planning being consulted or that a planning refusal was ignored ( Google for it )
