The main features of the Finnish landscape are a result of preglacial erosion processes and the structural lines of the bedrock. The microstructure of the landscape was created by the Ice Age and its melting processes. Upon this base, human activities have created a palimpsest of cultural landscapes. The article describes the effects of slash-and-burn cultivation, tar production, cattle ranging and some other forest uses to the forest landscape. 

The paper is based on a lecture given in the seminar ‘The forest as a Finnish cultural entity’, held in Helsinki in 1986. The PDF includes a summary in English.

The landscape preferences and attitudes of inhabitants of Puolanka, north-eastern Finland, to the effects of silvicultural practice on the forest landscape were studied by a postal inquiry. The effect of silvicultural practice on the forest landscape was mainly negative. Birch (Betula sp.) stands and mixed coniferous and deciduous tree species were the most preferred by the Puolanka inhabitants. The landscape preferences were related to socio-economic background of the inhabitants. The quality of the living environment also influenced the preferences, since uncommon features in the living environment were favoured most.

The article describes the two approaches which are evident in planning and management of nature and landscape. One is based on traditional architectural thinking, emphasizing the significance of subjective intuition and practical creative work. The other has evolved from the study of the economic utilization of natural resources, emphasizing the significance of rational thinking and scientific analysis.

This paper was presented in the ‘Man and the Biosphere’ programme project 2 seminar held on August 24–25 1978 in Hyytiälä research station of University of Helsinki.

The study deals with economic significance of forest landscape planning models used in regional planning in Finland. The »judge»-method is used among professional foresters working on private forestry boards in Southern Finland to define their view of what would be moderate level of costs of landscape management for private forest owners. A sample of 154 forest professionals working in district forestry boards in Southern Finland was sent a sociological questionnaire.

It was possible to form three hierarchical moderation classes by statistical grouping of judgement distributions. Prolongations in rotation ages and restrictions concerning ditching of forested bogs, forest read building and clear-cutting were considered the most immoderate models. Rather or wholly insignificant were evaluated such management models, which mean restrictions in »old fashioned» methods or which are already used in practice.

This paper deals with the problem of optimal multiple use of forests. The concept of attractive visual environment is analysed following the framework of conditional reflexes and conditionalization of needs. Uniformity of landscape preferences among a group of persons, forest professionals working in district forestry boards in Southern Finland, who have similar education and working environment is studied in empirical part of this paper. The sample of 154 persons were sent a sociological questionnaire.

The preference distribution of forest officers and forest technicians were found very similar. Only poor condition for wood production as a landscape feature was considered clearly negative. The answers show the demand for rational and active working environment as a factor directing the landscape preferences.

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

Two approaches were applied in measuring the scenic value of forest landscapes. In the field, the scenic value of forest lands representing clear cut areas, as well as young closed stands and mature stands with varying tree species composition, were assessed. In the laboratory, the scenic value of the same stands was measured with the help of photographs of the same stand. The same persons representing forest students (36 persons) and city dwellers (25 persons) made the evaluation.

Stands of moderate density containing individual tall trees and a coniferous undergrowth had the greatest scenic value, independently of the tree species composition. However, birch was preferred to Scots pine and Norway spruce. Measurements made in the field by means of interviews, and in the laboratory based on photographs, gave very similar results. Photographs seem to represent a reliable tool for estimating the scenic value of forest landscapes.

The environmental preferences of recreationists were studied at the forest stand level in this study. The hypothesis which has been drawn up on the basis of the literature has been studied by attempting to elucidate the environmental preferences of groups using two recreation areas owned by the City of Helsinki using interviews and questionnaires. The material consisted of 1,323 interviews supplemented by questionnaires.

The replies to the questionnaires showed that recreationists consider birch and Scots pine to be more beautiful than Norway spruce, and stands made up of several tree species to be more beautiful than stands of single tree species. They also consider mature stands to be more beautiful than young stands.

During the interviews, the attention of the recreationists was directed at the view formed by the interview stand. The scenic preferences for the stands were measured using adjectives which the interviewee was asked to use in describing his or her impression of the view which was pointed out. First of all, the results clearly indicated that from the point of view of the scenic value of the stand, the way in which the stand is organised to form a scenic aspect or a stand view is more important than its ecological structure. However, it is obvious that stands containing large sized trees in particular are in many ways more preferred than stands which are younger in their development stage. This should therefore be the case when changes in the stand view resulting from management measures are insignificant or difficult to see. The main tree species in the stand does not seem to have from the point of view of scenic preference as much significance as would have been expected judging by the questionnaire material.

Cavity trees contribute to diverse forest structure and wildlife habitat. For a given stand, the size and density of cavity trees indicate its diversity, complexity, and suitability for wildlife habitat. Size and density of cavity trees vary with stand age, density, and structure. Using Forest Inventory and Analysis (FIA) data collected in western Oregon and western Washington, we applied correlation analysis and graphical approaches to examine relationships between cavity tree abundance and stand characteristics. Cavity tree abundance was negatively correlated with site index and percent composition of conifers, but positively correlated with stand density, quadratic mean diameter, and percent composition of hardwoods. Using FIA data, we examined the performance of Most Similar Neighbor (MSN), k nearest neighbor, and weighted MSN imputation with three variable transformations (regular, square root, and logarithmic) and Classification and Regression Tree with MSN imputation to estimate cavity tree abundance from stand attributes. There was a large reduction in mean root mean square error from 20% to 50% reference sets, but very little reduction in using the 80% reference sets, corresponding to the decreases in mean distances. The MSN imputation using square root transformation provided better estimates of cavity tree abundance for western Oregon and western Washington forests. We found that cavity trees were only 0.25 percent of live trees and 13.8 percent of dead trees in the forests of western Oregon and western Washington, thus rarer and more difficult to predict than many other forest attributes. Potential applications of MSN imputation include selecting and modeling wildlife habitat to support forest planning efforts, regional inventories, and evaluation of different management scenarios.
