English title: What do the forest types stand for?
Original keywords: Waldtypen; Begriff; Zweck
English keywords: forest type; concept; purpose

The article aims to clarify the terminology and concepts related to forest type classification. The silvicultural meaning of forest type classification is to create classes so that the forests in one class have proximately same growth and yield conditions. The article describes the meaning of silvicultural forest type classification with seven objectives: to create a common height over age -site classification for all tree species; to achieve a common site classification practice for different countries; to achieve the natural height over age –site classifications that are easy to take into account by map drawing; to be able to treat the data for every class separately; to achieve a simple but illustrative description of the site characteristics; to have a foundation for special (applied) silviculture; to create as uniform classification of forests as possible for silvicultural, forest planning or forest policy purposes.

English title: Internal rate of return in forestry.

The concept of the internal rate can be defined as the rate of interest, which if applied to expenditures incurred at different times, gives a compounded sum equal to revenues compounded at the same rate for the same time. This concept has long been used in forestry, particularly concerning the development of a stand, because in this case there is a time difference between many items of expenditure and revenue. Several terms have been used or the notions derived on this basis. The term internal rate of return has begun to appear only recently. This article explains different variations of the concept and its different names, together with some related concepts and terms.

The PDF includes a summary in English.
