Raggytash walnuts, hazelnuts, crab apples, cherry, bilberry,edible fungi....to name but a few. But vehicle emissions and plant take up may put some off foraging. Hedgerows have also been called the long acre when it comes to grazing, especially either side of some of the old drove roads. Uncommon now but I have seen quite a few traveller's horses tethered on the roadside and the odd householder's goat. (where I am now there are feral goats-The story goes that they graze the more inaccessible ledges and the suicidal sheep have to find other avenues of escape)
