Among the heather - Simon Thorp intereged us with the ecological impact of the heather and grassland moors around the UK.  The importance of peat and the need to keep it moist as it retains massive amounts of CO2, the upland moors provide an estimated 70% of our drinking water, they provide entertainment - hillwalking, cycling shooting to ame but a few - wildlife and pasture. 

I had never really thought of the diversity and advanced management that goes into apparently barn ground

Thanks Simon.
