This deep, narrow gorge has long been famous for its unique biology. Steep limestone cliffs harbour woods which contain species found nowhere else in the world such as the Bristol Whitebeam. There are many exceptionally rare species, including Bristol rock-cress and some rare sedges. These plants have evolved in the isolation of the gorge, relatively secure from the changes around. Man’s influence has been present but was limited to an Iron Age hillfort, a now abandoned railway track and a small amount of coppicing. In June the bus firm Badgerline announced plans to use the abandoned railway as a bus lane. More tarmac and concrete.
