In reply to jim jones:
The guide mentions preservation of scree slopes in the Craig Arthur access section.
Believe it or not limestone scree is actually quite rare in this country and the scree slopes of the Eglwyseg valley are an important wildlife habitat. Further all the crags in the valley are part of the Clywdian SSSI.
I kindly request that all climbers and walkers please adhere to the access and approach routes described in the guide.
