Almost at one half of the localities their natural water regime has been substitially changed, at some other localities it has been at least partly changed and only at 2-5 localities the recent state of water regime can be considered more or less natural. 12 localities have been in the past heavily degraded by peat extraction. In spite of the high degree of deterioration, many of the remaining peatbogs can be still considered important for the biodiversity, since they represent important habitats for many rare and threatened plant and animal species. From the restoration measures suggested, the most frequent is the filling (blocking) of drainage ditches (18 localities) and the restoration of the regulated watercourses to increase the ground water tables (13 localities).
