The impact of carbon sequestration on the financial profitability of four tree plantation cases in Finland and the Philippines were examined. On the basis of stem wood growth; the accumulation of carbon in forest biomass, the formation and decomposition of litter, and the carbon flow in wood-based products were assessed for each reforestation case representing boreal (Finland) and moist tropical conditions (the Philippines). Using different unit values for carbon sequestration the profitability of reforestation was estimated for a fixed 100-year period on a per hectare basis. The financial profitability of reforestation increased notably when the sequestered carbon had high positive values. For example, when the value of carbon sequestration was set to be Twenty-five United States Dollar per megagram of carbon (25 USO/Mg C), the internal rate of return (IRR) of a reforestation investment with Norway spruce (Picea abies (L.) H. Karst.) in Finland increased from 3.2% to 4.1 %. Equally, the IRR of reforestation with mahogany (Swietenia macrophylla King) in the Philippines increased from 12.8% to 15.5%. The present value of carbon sequestration ranged from 39–48% and from 77–101% of the present value of the reforestation cost in Finland and the Philippines, respectively when a 25 USO/Mg C shadow price and a 5% discount rate were applied. Sequestration of one mg of carbon in reforestation in Finland and the Philippines was estimated to cost from 10.5–20.0 and from 4.0–13.6 USO, respectively.

According to 459 and 350 questionnaires sent in 1983 and in 1985, respectively, the households in the Rovaniemi region located in the Arctic Circle in Northern Finland, eagerly picked wild berries. In both years, four out of five households picked at least one species of berry. In 1983 the total amount of wild berries picked was 29.2 kg per capita. In 1985 it was 15.0 kg per capita. Three species, the lingonberry (Vaccinium vitis-idaea L.), cloudberry (Rubus chamaemorus L.) and bilberry (Vaccinium myrtillus L.) made up 96% of all the wild berries picked during both years. Most of these berries were picked for the family’s own use, but many were also picked for sale. In 1983, 43% of all berries picked were sold, in 1985, 19% were sold. The cloudberry, although difficult to find, is the most important commercial species and also for household use it is the most sought after wild berry. Only very small amounts of edible mushrooms were collected, 1.0 kg per capita in 1983 and 1.3 kg in 1985.

Temporal variations in use of an illuminated skiing route located near a town was examined. Three time-patterns (monthly, daily, hourly) were determined on the basis of empirical data. Preliminary data about the participation rates on Sundays of population living near the route was given. More than four thousand people reside within 0.5 km of the route. It can be supposed that on the best Sunday about 18% of the population participated in skiing.

The object of the study was to give a tentative indication of the realized economic significance of the principal forest (forestry land) uses in Finnish Lapland. Data concerns the years of the 1970s. Nowadays timber harvesting generates a major part of the total value of production. Recreation (tourism) is in second place. Reindeer husbandry, collection of berries and mushrooms and hunting together produce, in the best years, an output value which is about one fifth of that of timber harvesting. Non-timber uses together produce a rather significant portion on the total value of the integrated forestry output.

The purpose of this study was to gain an insight into research problems and themes in multiple use of forests from a practical viewpoint. An inquiry concerning multiple use problems was sent to 597 organizations whose work related to multiple use of forests. Replies yielded 1,857 suggested research themes which were divided between different uses of forests. About half of the suggestions concerned the relations between timber production and the other uses of forests. The many propositions are due to the fact that timber production in its intensity has strong influence on the other uses of forests. The results of the study have been used in the planning of research in the multiple use of forests.

The article is a summary of a long-term research programme which has been prepared at the Finnish Forest Research Institute. The objective of the programme was to define and subdivide the field of multiple use research to be done at the institute, and so improve both the research planning and the coordination of the work in this field between the different research departments.

The profitability of fast-growing trees (Eucalyptus camaldulensis Dehnh., Acacia mangium Willd. and Melia azedarach L.) was investigated in the north-eastern and eastern provinces of Thailand. The financial, economic, and tentative environmental-economic profitability was determined separately for three fast-growing plantation tree species and for three categories of plantation managers: the private industry, the state (the Royal Forest Department) and the farmers. Fast-growing tree crops were also compared with teak (Tectona grandis L. f.), a traditional medium or long rotation species, and Para rubber (Hevea brasiliensis (Willd. ex A. Juss.) Müll. Arg.) which presently is the most common cultivated tree in Thailand.
The optimal rotation for Eucalyptus camaldulensis pulpwood production was eight years. This was the most profitable species in pulpwood production. In sawlog production Acacia mangium and Melia azedarach showed a better financial profitability. Para rubber was more profitable and teak less profitable than the three fast-growing species. The economic profitability was higher than the financial one, and the tentative environmental-economic profitability was slightly higher than the economic profitability.
The profitability of tree growing is sensitive to plantation yields and labour cost changes and especially to wood prices. Management options which aim at pulpwood production are more sensitive to input or output changes than those options which include sawlog production. There is an urgent need to improve the growth and yield data and to study the environmental impacts of tree plantations for all species and plantation types.
