The forest site classification system used in Finland is based on ground vegetation rather than the wood production capacity. A. K. Cajander has presented a detailed classification of different forest site classes in different parts of the country. This study focuses on the forest site types of Northern Finland, which are less well defined. The article presents detailed vegetation analysis and lists of plant species in different forest site types in Northern Finland. In contrast to southern parts of Finland, both the natural Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies (L.) H. Karst) stands are uneven-aged in the north. The forests are also relatively thin. There is a marked difference in height of trees between the richest and poorest sites, but the dominant trees of the same site type were of similar height both in the north and south part of the study area. The differences in the height of dominant trees seem to be smaller than in Southern Finland. Also, in windy areas prone to snow damage, climate conditions can affect tree growth more than the forest site type. In more sheltered areas forest site type determines forest growth.
