English title: The zoogeographical significance of the birch zone in Fennoscandia.

The subarctic-subalpine mountain birch forest zone discerns Fennoscandia from other northern regions. The zone offers protection against wind to animal life, protects soil from evaporation and increases humidity. The article reviews distribution of vertebrate and butterfly species in the birch forest zone. There are no vertebrates that occur solely in the birch forest zone, and only few live mostly in the zone. Many species live either both on the birch forest zone and the treeless fell area above it, or in the birch forest zone and coniferous zone below it. Similarly, no butterflies occur only in the birch forest zone, but the zone is the main habitat for some species. Consequently, the subarctic-subalpine birch forest zone cannot be considered to be an independent ecozone but a transitional zone between regio silvatica and regio arctica that is nearer to the northern coniferous zone than the fell region

K. J. Valle. (1929). Können die südfinnischen Seen vermittels der umgebenden Vegetation und Flora bonitiert werden. Acta Forestalia Fennica vol. 34 no. 23 article id 7236. https://doi.org/10.14214/aff.7236
English title: Can the seas in southern Finland be classified according the productivity by means of surrounding vegetation and flora.

The aim of the study is to define to which extent the productivity of seas in south Finland, and especially the production of animals in sea bottom, can be determined according the forest site classification given to the land areas around the sea, meaning that the productivity class is the same for the forest and the sea. The data for the study has been collected in state owned forests in Evo in middle Finland, in Karelia around the Finnish and Russian border and in southern parts of Karelia.

Where the forests are more barren, VT or Ct types, also the seas have lower productivity, they are oligotrophic or mesotrophic. However, the less barren surrounding forests are not a clear sign of the productivity of the sea. As a result the productivity level of a sea can be estimated relatively good by the fertility of the surrounding areas, though not in all cases. 

The volume 34 of Acta Forestalia Fennica is a jubileum publication of professor Aimo Kaarlo Cajander.

The PDF contains a summary in German.

English title: Studies on fishing grounds in State forest Evo.
The aim of the article is to describe the different fishing grounds of state owned areas in Evo and to compare them with each other. Seven lakes (Valkea-Mustajärvi, Iso Mustajärvi, Ylimmäinen Rautjärvi, Kaitalampi, Hautajärvi, Syrjänalunen and Onkimajärvi) are presented. The nutrition production of the lakes and the regulation of the fish stock in the lakes are discussed.
