Management of the wet heaths is required to restore favourable condition by bringing about structural divergence and by suppressing scrub. It is also vital to prevent the drying out of these areas. Without the instigation of some kind of sympathetic management on this part of the heath the conservation value will continue to decline rapidly. Burning of wet heath can be helpful , but due to the wet nature of the ground, the use of machinery for cutting is not always appropriate or possible. The most sympathetic and effective management of such areas is to graze them. The management options for these parts of the common will need to be appraised as part of the stakeholder engagement process. 45
