What The Science Says website checks out another claim:
Claim: 75% of the world's heather moorland is in the UK
This figure is widely quoted by many interested parties, holding different views about the management of such environments:
Ecologist: Grouse Shooters Thrive on Heather Moorlands
Climate News Network: ‘Amazon of UK’ being destroyed for grouse shooting
The Moorland Association
Game & Wildlife Conservation Trust: How much upland heather moorland is in the UK?
BASC: Grouse Moor Landscape
The assertion was recently challenged by Dr Steve Carver on his blog.
