John W. Harshberger. (1929). The forests of the Pacific coasts of British Columbia and Southeastern Alaska. Acta Forestalia Fennica vol. 34 no. 5 article id 7218. https://doi.org/10.14214/aff.7218

The vegetation in the Pacific coasts of British Columbia and Southeastern Alaska resemble the vegetation in the northern Fennoscandia. The national forests have been divided in two parts: Tongass and Chugach national forests. Both of the forests are fairly uniform in their vegetation. The forests have few coniferous tree species as the dominant species from south to north, Sitka spruce (Picea sitchensis (Bong.) Carrière) and western hemloch (Tsuga heterophylla (Raf.) Sarg.). It is difficult to distinguish forest site types, but it is probable that the forest lands in Alaska and British Columbia could be delimited to similar forest site types as professor Cajander established in Finland.

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

Mark L. Anderson. (1929). Forest types in Scotland. Acta Forestalia Fennica vol. 34 no. 2 article id 7215. https://doi.org/10.14214/aff.7215

The primeval forests of Scotland were deforested in the Lowlands by the end of 1500th century, and in the end of the 1800th century also the best forests of the more inaccessible Highlands were exploited. The 1800th century witnessed an outburst of afforestation among the private land owners. With help of nursery work and use of exotic species, the work was successful. Silviculture of Scotland would benefit of a reliable method of site classification. The complexity of the geology and topography, and the lack of mature natural stands complicate the establish a forest type classification similar to the one Prof. Cajander has evolved in Finland. The aim is to establish forest site types which include similar types as in Finland, with possibly additional types in the grass-herb series.

English title: Studies on mensurational significance of forest site types as part of preparation of Finnish growth and yield tables.

New growth and yield tables were prepared for Southern Finland. To finalize the tables, it had to be determined whether the forest site types developed by Cajanus could be used in mensurational research.

Comparative study was performed in 1916-1919 to study the growth of the trees in different forest site types. Total of 467 sample sites were measured in Southern and Central Finland. All the forest site types were found to have a distinctive vegetation typical to the site. It can be concluded that the ground vegetation can be used to determine the forest site type. The growth of trees was different in different forest site types, yet similar within each site type. The forest site types are uniform, natural and easy to determine, and can thus be used to classify the forest stands and used in mensurational research and a basis to growth and yield tables.

The PDF includes a summary in German.

Raf. Björkenheim. (1919). Beiträge zur Kenntnis einiger Waldtypen in den Fichtenwaldungen des deutschen Mittelgebirges. Acta Forestalia Fennica vol. 6 no. 3 article id 7014. https://doi.org/10.14214/aff.7014
English title: Writings on knowledge on forest types in spruce forests of German “Mittelgebirge” (mountainous areas).

The data has been collected in spruce forests in mountainous areas of Germany: Fichtelgebirge and Böhmerwald in Bavaria, Erzgebirge in Saxonia. The studied characteristics of the stand were: growth of the trees in height and diameter, and the ground vegetation. The stands were classified according Cajander’s forest site classification. The article presents the most common plants and other characteristics of every forest site type and studied stands. The relation of the height of the trees and their age is represented in diagrams for every forest type.

The presence of indicator plants is somewhat dependent on the stand age and crown coverage. The amount of species is lowest when the crown coverage is at the greatest.

As conclusion of the study it can be seen that the growth of the stand differentiates clearly depending on the forest site type, being greater at the more nutritious sites. Since the differently growing stands need different management, it would be natural to direct the management of the stand according the forest site type.

English title: About forest site types.

The study is based on research in Germany, Austria, Switzerland, north Russia and Siberia, and Finland in years 1906-1908. The objective of the study is to find means to create forest site classes or forest types to direct practical forest management.

The article presents the classification of forests into site classes (Oxalis-Majanthemum type, Myrtillus type, Vaccinium type and Calluna type). The second part of the article represents different methods to calculate growth and yield tables for different forest site types. The conclusion of the study is that forest areas with similar vegetation and forest type can be handled in one way for forest management.
