Sir, -When there is talk of "over-grazing" on the mountains of the West, I wonder if people really realise what it is like.I enclose a couple of photographs of a mountainside near the Bangor trial in Mayo. Twenty-five years of wild flowers - bellheather, sasxifrage, bedstraw, orchids, milkwort and many others. Now it is trampled mud, with a few tufts of scrubby grass - and there are still herds of sheep trying to graze on the land.How are people supposed to enjoy the beauties of the countryside when they are subjected to this wasteland? -Yours, etc.,Mrs Rosalind Davies, Newport, Co Mayo.
