Abstract
During a period of 2 years and 3 months (1 January 2001 - 20 March 2003) Mycoteam had 3161 consultations in buildings in southern Norway, 1428 revealing damage from decay fungi. One consultation often revealed several occurrences of fungi, and the total number of occurrences of decay fungi was 3434. Thirty-five different species/genera/groups of decay fungi were recorded. During this period brown rot was more frequent (77.4 %) than soft rot (19.2 %) and white rot (3.4 %). Coniophora puteana (16.3 %) and Serpula lacrymans (16 %) were the most frequently identified species. Different species of the genus Antrodia were recorded in 18.4 % of the occurrences, while the group Corticiaceae accounted for 5.7 % and soft rot for 15.8 %. Investigations of damaged structural parts of buildings showed that decay fungi were most common in walls (18.3 %). Floor damage accounted for 13.4 % of the damaged structures and roofs for 8.8 %. Nearly all species and groups of the investigated fungi were most common indoors. Gloeophyllum sepiarium on the other hand was most common outdoors, and Dacrymyces stillatus was exclusively found outdoors. The Norwegian data were compared with published time series data from Denmark (1946-66, 1966-71, 1974-75, 1982) and Finland (1978-84, 1985-88). S. lacrymans and C. puteana were the most frequent species in these datasets too. Antrodia spp. were also common in the Finnish reports, but barely recorded (as identified species) in Denmark. In both the Danish and the Finnish data, damage to floors is the most frequently recorded structural damage in buildings.

Abstract
Economic externalities of mitigating measures to reduce sheep losses to carnivores are not sufficiently addressed in Norwegian nature management. Evaluating such measures involves a "scale” problem: outfield (i.e. open range) grazing sheep have quite small home ranges, large carnivores from hundred to several thousand km2. Because these ranges are a different order of magnitude, exposure to mitigating measures taken in any sheep home range area might influence predatory behaviour outside that area. These external effects impact on society, the environment and other farmers and could outweigh any advantages. Scale consideration is of crucial importance in designing field research projects to explore such issues.

SNS-meeting 2004 in Nordic Forest Inventory was held at Sjusjøen, Norway, September 6-8, 2004. This publication is a collection of all the subjects dealt with at the meeting. The articles are written by the speakers on the meeting. The subjects were country and team reports, lidar measurements in forest inventory, national forest inventory, remote sensing studies, forest planning and current topics in forest modelling.

Entrepreneurship can be defined as the process of transformation of new economic opportunities into values in the markets. It has become the engine of economic and social development throughout the world. Rural areas have some fundamental disadvantages for enterprises and entrepreneurship: they provide less skilled labor, less non-traded inputs to industry and at a higher cost, and finally but perhaps most importantly, rural areas are less attractive in terms of access to knowledge and information than concentrations of industries and population.Often the actions for new entrepreneurship in rural areas are targeted to the production and use of natural resources e.g. in agriculture, fishery, forestry, processing and nature-based tourism. Rural areas also have some fundamental advantages for enterprises and entrepreneurship as they provide cheap location for the enterprises, good quality of life for the employees and reliable unskilled labor.Entrepreneurship policies can be divided into policies that support the demand or supply for entrepreneurial activities.The (i) demand side policies aim to elaborate the opportunities to engage actors in entrepreneurial activity. They include, for example, deregulation of entry in the markets, privatization of public services and promotion of firm linkages or clustering. The (ii) supply side policies focus on promoting the capabilities of individuals and firms and facilitating access to resources, for example, via education and training, incubators, micro-credits and other financial incentives and various promo-campaigns. Entrepreneurship policy can also (iii) change the risk-reward profile of an entrepreneur by shaping taxes, subsidies, labor market rules and bankruptcy regulations. The aim of this paper is to consolidate the knowledge on the applied entrepreneurship policies (i-iii) in forestry in Finland, Norway, Japan, Australia, the Philippines and the United States. Aside this, the paper aims for identifying research needs and gaps of knowledge on forest sector entrepreneurship to suggest approaches for future research.
Abstract
Up to ca. 1960, the forest sector was the largest export sector in Norway. Since then its importance has decreased, until in 2003 the export value totalled only 2,5 % of the export sector. The import of forest products constituted a relatively higher share of the total import value than the export (about 3,3%). Pulp and paper, mainly newsprint, is the most important export product. The annual cut has declined 30 per cent over the last decade and in 2003 totalled about 7.5 million cubic metres. The reasons for this decline are not fully understood, but changes in ownership structure, low unemployment rates and good job opportunities outside of the forest sector and the abolition of cost-share programs are certainly some of the explanation. Private non industrial owners own 78,5 % of the forest area and the average size of a forest property is 57 hectares. Almost all fellings are certified, and there is an intensive ongoing debate on the need for protection of a larger forest area. There is a large potential for developing non-wood products and services, and the forest owners association have companies and organisations dealing with this. There is a demand from both domestic and foreign customers for non-wood products and services but the cooperation with the domestic tourist industry still has to be improved to coordinate this effectively. There is a weak entrepreneurship culture in the forest products industry, with a few regional exceptions. The culture is mainly production oriented and market competence and international orientation is needed. Compared with other industries in Norway the level of education is low in the forest products industry. A large public program was started in 2002 to stimulate innovation and competence building activities in the forest products sector.
