This special volume of Acta Forestalia Fennica is published in memory of professor A.K. Cajander (1879-1943), who was one of the founders of the Finnish Society of Forest Science. It contains a short biography, a complete list of his literary works and one of the papers on forest types he has written.

This article contains professor A.K. Cajander’s paper on the theory of forest types in English. The article can be found in Finnish in separate PDF (article id 7695).

The idea of forest types was developed by professor Cajander first in 1904-1909, when he was working as a student in the Evo Forestry Institute. The first publication in 1909 was followed by intensive research and the findings of the investigations were published in 1929 in Acta Forestalia Fennica 29 (Metsätyyppiteoria, The theory of forest types).

When classifying forest growing sites, the purpose is to combine those having the same or approximately same yield capacity, and to separate into different classes those whose yield capacity is widely different. The article states that site quality classification is a necessity in organized forest management as it gives a basis for all forest calculations concerning with yield and profit. The principles of site classification and its meaning in forest management is discussed.

Different birch species hybridize very easily with each other and identifying the species of an individual tree is difficult. The article gives the description of one variant from Russia and the author suggests naming it after Prof. Cajander.

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

Tree stands in the boreal treeline ecotone are, in addition to climate change, impacted by disturbances such as fire, water-related disturbances and logging. We aim to understand how these disturbances affect growth, age structure, and spatial patterns of larch stands in the north-eastern Siberian treeline ecotone (lower Kolyma River region), an insufficiently researched region. Stand structure of Larix cajanderi Mayr was studied at seven sites impacted by disturbances. Maximum tree age ranged from 44 to 300 years. Young to medium-aged stands had, independent of disturbance type, the highest stand densities with over 4000 larch trees per ha. These sites also had the highest growth rates for tree height and stem diameter. Overall lowest stand densities were found in a polygonal field at the northern end of the study area, with larches growing in distinct “tree islands”. At all sites, saplings are significantly clustered. Differences in fire severity led to contrasting stand structures with respect to tree, recruit, and overall stand densities. While a low severity fire resulted in low-density stands with high proportions of small and young larches, high severity fires resulted in high-density stands with high proportions of big trees. At water-disturbed sites, stand structure varied between waterlogged and drained sites and latitude. These mixed effects of climate and disturbance make it difficult to predict future stand characteristics and the treeline position.
