Fred
are these various sites reclaimed mining areas? They certainly look good and seem ideal for orchids.
Tony i will answer this because i am not sure i have told Fred the story behind this site,it was never a mining site these fields was owned by a farmer i used to know,he donated the land to the wildlife trust,he never used chemicals on them and they were always used for hay for his cattle,the farmer is no longer a farmer he sold a massive chunk of land to a building developer and made a fortune.
