An SSSI and a Special Area Of Conservation, the vegetation in the gorge area is especially important. Among the rare species to be found in the area are Scarce Turf-moss, Tunbridge Filmy-fern, Deratocarpon miniatum and Rock Fingerwort. The rock face and exposures are also nationally important geological features. Vegetation clearance and modification of the rock faces is to be avoided without prior consent from the Forestry Commisson and the clearance of trees and undergrowth has in the past has led to the real threat of access restrictions.
Groups are advised to contact the Forestry Commisson before using the site, and a formal concordat for the use of the gorge and the rocks has been agreed between the Forestry Commisson and outdoor centres. Forestry Commisson contact for more information on the concordat, contact Paul Dann on 01558 690325, mobile 07789 651026.
