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.

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

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.

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

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.

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

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.

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

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.

Abstract | Full text in HTML | Full text in PDF | Author Info
The perception of the Finns about forests and forestry has been tracked over a period of more than 15 years. The results of this survey constitute the longest sequence of data of this type at the national level anywhere in the world. The people’s perception of reality represents a factor that influences decisions about policy. For this reason, it deserves monitoring and analysis. Forests in Finland are highly meaningful to the people, who are generally well informed and link their opinions to the facts that they are able to observe. The variability of the responses over the years of the survey is not significant. Silviculture and forest management are perceived as good by most Finns. Finns are aware that more forest grows than is harvested, and they also know that some raw material is still imported. However, they demand that more forest be protected. Finns are aware that their forest industry is not performing well at the international level. They also demand an increased wood supply for building construction. Forest harvesting is viewed as a source of employment and welfare.

Abstract | View details | Full text in PDF | Author Info
This study reports on national survey results concerning mushroom picking in Finland during four separate years: 1997–1999 and 2011. The material was collected by mailed questionnaire surveys amongst Finnish households. The sample size varied from 1858 (in 1998) to 6849 households (in 1997) and the response rates varied from 51% (in 2011) to 70% (in 1999). The results indicate that both the rate of participation in mushroom picking and estimates of the quantities collected varied greatly depending on whether the survey was conducted in a favourable or unfavourable year. In 1998, when the mushroom crop was abundant, a total of 47% of all households were engaged in picking and the total harvest was 16.1 million kg. In 1999, when the crop was poor, the estimates were the lowest (23% and 3.3 million kg, respectively) and in a year with a relatively abundant crop (2011), the estimates were 42% and 15.0 million kg, respectively. Mushrooms were collected mainly for home use, which accounted for 85–90% of the total harvest depending on the year. Only a small proportion of all households (0.3–1.3%) were engaged annually in commercial mushroom picking. In 1997–1999, milk caps formed the major part of the total amount picked (i.e. 37–53% depending on the year), whilst in 2011 their share was approximately one fifth of the total harvest. The results also indicate that the proportion of ceps in commercial picking has increased since the 1990s

Keywords: bilberry; cowberry; total berry yield; yield variation; utilisation of wild berries
Abstract | View details | Full text in PDF | Author Info
So far, only rough estimates for the utilisation rates of wild berries in Finland have been available. One reason for this is that there has been a lack of empirical-knowledge-based studies concerning total yields of wild berries and their yield variations. This study had three aims: 1) total bilberry and cowberry yields of an average crop year were calibrated for different (abundant and poor) crop years using the inventory data on wild berries collected by the Finnish Forest Research Institute (1997–2008); 2) national utilisation rates of bilberries and cowberries were calculated for three different berry years 1997–1999; and 3) regional utilisation rates of these berry species were calculated for the year 1997. According to calculations, annual bilberry yields in Finland vary from 92 to 312 million kg. For cowberry, the range of variation in total berry yields is from 129 to 386 million kg. It was also found that approximately the same proportion of the total yield of bilberries (i.e. 5–6%) was collected between 1997 and 1999. Utilisation rates of cowberries were also quite constant varying from approximately 8% to nearly 10%. In 1997, bilberries and cowberries were utilised most intensively in the eastern parts of the country and in the Oulu-Kainuu region. The results of this present study describe the situation before the phenomenon of foreign pickers. It can be presumed that commercial wild berry picking by migrant collectors has so far affected both national and regional utilisation rates of wild berries.

Abstract | View details | Full text in PDF | Author Info
Costs generated by nature conservation are repeatedly under discussion. Most often the costs of conservation are estimated as aggregate figures at the national or regional level or alternatively, for a forest owner. In this study they were examined at the local level, in the forestry dependent municipality of Ilomantsi in Eastern Finland. The estimations of lost net revenues (stumpage income less silvicultural costs), wages, entrepreneurial income and profits, employment and value added were based on alternative forest management plans calculated for conservation areas. The annual losses as regards employment during the first decade were estimated to be 5.7–20.4 jobs. Later, the employment effects were estimated to be 2.4–6.3 lost jobs. Although the value added lost during the first decade was estimated to be at maximum only 3.4% of the present total value added of the municipality, the share of the value added of forestry was estimated to be higher than the mere protected forest land share would indicate. The use of conservation areas for forestry would create a moderate increase of employment in forestry, i.e. 3.8–14%, during the first decade, but it would later stabilise at a much lower level. Employment impacts at the municipal level were estimated as very small (at maximum 0.9%), but on the other hand, for some villages even single jobs may matter. The main reasons for the minor impacts were the high mechanisation rate of logging and the major flow of stumpage income outside the locality.
