Abstract | View details | Full text in PDF | Author Info

The principal method of transporting timber for long distances in Finland is floating. It is supplemented in the principal forest districts by transport in ships, by rail and lorries. However, in north-eastern and northern parts of the country the main water systems flow into Arctic Ocean, and floating cannot be used to transport timber. The area does not have railroad and road network is sparse. The poor accessibility has hindered the use of forest in the area. A division of the Tuntsa-Oulanka and Arctic Ocean water system area into supply areas is presented.

Abstract | View details | Full text in PDF | Author Info

The valuation of forest land for financial accounting purposes is usually performed only when using methods that are based on wood resources. In the yield based methods, the book value of forest land and wood resources form one totality. In the first case, forest land in a separate land account usually has same value in the beginning and end of the accounting year. For instance, the costs of forest improvement are considered capital costs. Forest land can be valued either by multiplying the average hectare price of land with the hectares, or using separate unit prices for the different forest site types. Different ways to value forest land are presented, comparing the forest site type classification developed in Finland and the traditional method based on average height of the trees used in Central Europe. The study shows that values of forest land has relative nature.

Abstract | View details | Full text in PDF | Author Info

The drained peatlands regenerate usually well, and artificial regeneration by sowing or planting has been rare. Field trials of Norway spruce (Picea abies (L.) H. Karst.) were established in northern Satakunta in Western Finland in three drained peatlands in 1934. Sowing trials of Norway spruce consisted of patch and broadcast sowed sample sites in treeless bogs and under protective forest. The seedlings of spruce were planted either under protective forest or in treeless peatland.

The results show that artificial regeneration of Norway spruce succeeds best under protective forest. The best tree species for upper storey is Betula sp. which grows fast and controls growth of ground vegetation. The peat is relatively decomposed on those peatlands that are suitable for spruce, and breaking of the surface of the peat is not recommended. In the sowing trials, breaking of the upper layer of the peat caused frost heaving, cracking of the dried surface and sticking of mud in the seedlings in the patch sown sample site. The shoot and root growth of seedlings of the broadcast sown site was better than seedlings of the patch sown site. The planted spruce seedlings seemed to be more susceptible for spring frost than the seedlings in the sown site. The plants of seed origin succeeded in general better than the planted seedlings.

E. A. Martin Hagfors. (1939). Critical views on the economic theory on forestry: with special consideration on Nord-European circumstances. Silva Fennica vol. 47 no. 2 article id 7342. https://doi.org/10.14214/aff.7342

Abstract | View details | Full text in PDF | Author Info

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.
