This is an area where I spend a great deal of my spare time. It’s a wild unforbidding place, one that captures the very sprit of the Tees in its upper reaches. Reaching for a single adjective to describe this landscape would be to call it a ‘wilderness’. However, in 1971 this river was tamed by the industries in Teesside when Cow Green reservoir was built. Public knowledge of the rare and diverse specious of plant life that surrounded the proposed reservoir was limited and the conservationists lost their battle against the industrialists. The reservoir no longer serves industry on Teesside. The oil crisis of the early 70’s saw to that. It did however bring to the attention of the media and public, the importance of this environment.
