Literature knows a variety of forest and timber related balances and even wider variety of calculations concerning the themes. The article presents forest and timber balances divided into three categories, based on their purpose.
The three categories are: 1) (national) economic balances for calculating the sustainability of forest use and sufficiency of forest resources; 2) balances of yearly harvesting rates for mostly commercial purposes, but also economic uses; and 3) balances of timber demand and those for balance between supply and demand, especially for foreign trade.
Finally the author critically views the use of balances to describe the amounts of wood used in industry.The PDF contains a summary in Finnish.
The article contains three parts and a summary. The first part presents the common foundations of forest economics and forest management. The second part critically discusses the concept of sustainability and the third part takes critical view on the theories on profitability.
The author concludes by stating that the literature shows there are some old principles of forest management that always arise when the forest science progresses. The economics of forest management has been neglected in the sense that it should be acknowledged as self and not as mathematical problem as it has been handled in many theories of national economy, e.g. land rent theory. The science seems the turn back to previous findings as they are proved right again.

Studies by G. König are the main source for the profitability theories of forestry. He was one of the first economists developing the forestry practices more towards profitability aspects. His doctrine presented the first steps of current forest related trend of ideas and hence so significant in the later development of the discipline.
The article presents the life of G. König and two of his most important works: “Anleitung” (introduction) from the year 1813 and “Forstmathematik” (Mathematics of forest) from years 1835 and 1854

The article has two parts: the first are the common principles of forestry and forest economics and the second part presents different theories of forest economics. The aim of the study is to find out how the best possible economic result can be achieved from forest management and use of forest resources.
The first part presents the economic foundations of forestry; the division between following the concept of economic profitability in forestry and forest management; concepts of capital and operating result in forestry; and productivity and profitability. It discusses the idea of economy as a dynamic entity instead of static.
In the second part the different economic theories related to forestry and forest economics are presented. Theory on the highest interest on forest capital, theory of sustained yield management system, land rent theory, theory on forest profitability and dynamic economic theory are discussed.The PDF contains a summary in Finnish.
To achieve a continuous and constant timber flow over a longer time period, the forest holding structure should be close to normal forest or regulated forest. Concept of normal forest is presented as the model of achieving the highest possible sustainable yield and hence also the best economic return. The article discusses the regulations on the management of a forest holding with the view on regulating the forest yield.
Felling need to be planned according to the forest site and tree species. The main tree species for silvicultural purposes are pine, spruce and birch. After the widely used controlled burning of forests the state of Finnish forests is mostly weak and far from the “normal forest”. Majority of forests are of young and there are lots of broadleaved forests. Because of the great variation of the forest sites and their productivity as well as the small size of holdings in Finland, the selection of forest management regime, mainly the felling style (clear cut or light selection) is also important. The idea of management plans is represented.
