In reply to olddirtydoggy:
> I remember the foot and mouth thing a few years back and wildlife return to areas that had not seen reclusive species for a while.
During the Foot and Mouth outbreak, the effect was to keep both humans and grazing animals off upland ground. So, for example, bracken growth got naturally reduced during the period since other species of flora were finally able to compete with it without being eaten by sheep.
My recollection is that Ring Ouzels returned to Stanage during the Foot and Mouth outbreak, and now breed there every year.
