A strip survey was made to define the forest and peatland site class distribution and the condition of the forests in Savo and Karelia in central and eastern parts of Finland. According to the survey, 24% of the forested lands are peatlands. Fresh mineral soil sites (26%) were the most common mineral soil site type. Intermediately dry forest soil sites covered 22% of the area, forest sites with grass-herb vegetation 12,79%, rich grass-herb forest soil sites 3,16% and dry forest soil sites 9,59% of the forested area. The most common tree species were Scots pine (Pinus sylvestris L.), 39%, Betula sp., 26%, Norway spruce (Picea abies (L.) H. Karst.), 18%, and grey alder (Alnus incana (L.) Moench), 10% of the forest land. The article includes a review about the wood harvesting in the forests, and their present silvicultural state. According to the study, about 30% of the forested lands (not including peatlands) were unproductive; mostly mixed alder and birch stands of poor quality or open lands.

The article presents a survey on distribution of fertile lands, soil types and site classes in Savo and Karelia in the central and eastern parts of Finland. The survey was based both in existing publications and statistics, a line survey, and visual observations during field trips. The site quality classification is based on the vegetation and occurrence of indicator plant species. The article lists distribution of indicator species in different forest site types on maps of the area. In addition, a review of history of land use and agriculture give indications of the location of the fertile lands in the area. A map of the forest site types in different parts of the area illustrate the data collected from the different sources.
