English title: Studies on the microbiological differences in soil between the forest types.

Earlier studies show that different kind of biological processes occur in the soil of different forest types. These differences may be due differences in microbiology of those soils. This article studies these differences.

Soil samples from five different forest types were collected from the Ruotsinkylä research forest in three different seasons: in January, March and September.

The amount of bacteria in the samples is at the lowest in March and highest in September.   During the winter more anaerobic bacteria were found. The amount of denitrifying bacteria is higher in the soil than amount of nitrifying bacteria.

The results indicate that the species composition of soil varies between the forest types in the same manner than the vegetation composition above the soil. However, this study is only a preliminary and more knowledge is needed about the discipline before practical implications can be drawn.

The PDF contains a summary in Finnish.

English title: Knowledge on the forest types in Estonia.

The article summarizes the observations about forest types from different parts of Estonia. The chosen examples represent the normal forest where age class division is natural and the species composition has not been altered through felling or grazing. These are mainly found in the areas of earlier manors of the nobility. The samples are only from mineral soils. Vegetation analysis and middle-European height-over-age-survey were made.

Because of the great share of herb-rich-forest the forest type classification for Estonia is complex. There are many types that have not been described earlier.

The study describes the characteristics and the vegetation types of the heath forests, fresh forests, half-herb-rich-forests and herb-rich-forests.        

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

English title: Forest types in Latvia.

The article discusses the different methods to classify forest sites and applies the methods to classify forests in Latvia. The three methods are: height-over-age classification, from standpoint of floristic (botanical- plant geographical standpoint), and forest types. A good classification method must: describe the main characters of a site illustratively, the classification units need to relate to each other, and the classification method is easy to use in practice. In contrast to other methods, by forest type classification the stand and the site are considered as whole and hence it is considered as the best of the three.

There is one classification system for the whole Latvia. The forests can be divided into permanent and transition types. In the permanent types the site factors stay rather unchanged and the site characters tally with the requirements of the dominant species. sites where the current tree species produces less than optimum growth are classified as transition types.

The forest types have changed over the time because of leaching of the nutrients from the soil.
