Well I did wonder that the other day flowerofthewest. I was expounding the theory that in most parts of England the land that was previously wooded has been heavily farmed for a long time. On the train from Crewe to MK the other day it was fields all the way, lot of them monoculture grass/cereal. Hardly a bluebell or other wild flower in sight. Even the few where you could see the mediaeval ridges will have been farmed for 1000 years or more. In Wales there has never been such intensive farming - but much deforestation of hillsides etc for firewood or to fuel small furnaces. Glad I was thinking along right lines
