Data are presented from 1312 km of inventory transect, 6030 relascope sample plots and 21 700 ditches. Of the Finnish peatlands studied, more than 60% were pine mires, almost 20% were spruce mires and less than 10% each were treeless mires and paludified upland forest sites. The survey included the condition of the drainage networks, and the post-drainage development of the tree stands, their structure and silvicultural condition.
