The type of the peatland and its classification as forest site (height-over-age-classification) are important information when the drainage potential of a peatland is defined. The gradient and thickness of peat bed are also significant.
The observations for the study have been collected in state owned forests in middle-Finland. The thickness and gradient variations have no clear differences between different types of peatlands. The results show that from the view of drainage for afforestation, the peatlands that are good or suitable for afforestation are flatter and more even that those less suitable. The more suitable peatlands also have thinner peat bed and bigger gradient.
The volume 34 of Acta Forestalia Fennica is a jubileum publication of professor Aimo Kaarlo Cajander.
The article is based on the work “Metsänhoidon perusteet I” [The fundamentals of Forest management I] by the author (1919 in Finnish). The different processes of the soil and the vegetation are dependent on the climatic conditions, but also affect each other. The article presents the climatic zones of the earth and their most important characteristics in regard of cultivation of (to respective zone) exotic trees species and agriculture.
