The southern border of occurrence of high moors is only known for western Finland. In other parts of southern Finland the high moors are bordered with Karelian mixed moor type. The article presents observations on high moor alike moors in middle Finland. The characteristics of these high moors are described and compared with other moor types in the area.
Morphological and hydrographicalas well as vegetation related characters are presented. The most important character of the moors increasingly occurring when moving from south the north is decrease in convexity of the moor. In western part of the country clarity of raises, in eastern part of the country the abundance of large dwarf shrubs are also typical. Climatic differences between west Finland and east Finland seem to cause the differences.
Results indicate that the climatic reasons, meaning the more continental climate in eastern part of the country, is the reason that there are fewer high moors in eastern Finland than in western Finland. The areas with tendency for developing as high moors develop themselves as drier forest high moors. It is reasonable to limit the north border of occurrence of proper high moors further south than what has been done.
