English title: The place of spruce-pine mires and oligotrophic spruce mires in Finnish peatland site type classifications

Abstract

In Finland three different mire classification systems can be distinguished: 1) those for ecological purposes based on detailed botanical surveys, 2) those for scientific forestry research purposes, and 3) more extensive systems for practical forestry purposes. All systems are based upon Cajan-der's site-type principle whereby habitats which are ecologically similar are considered to support a similar vegetation. The classification (site type names, analogy/correspondence, nutrient status level) of spruce-pine mires and oligotrophic spruce mires according to the above-mentioned systems is compared. Some criticism concerning especially the confusing naming of the same type is presented. The varying post-drainage suc-cession in these site type groups is also discussed. Finally an attempt to distinguish the more oligotrophic spruce-pine mires from the less oligotrophic ones is made. Keywords: Drainage, mire classification, site type, succession, trophy
