The city of Oslo is surrounded by large forest areas, the socalled Oslomarka, which are intensively used for recreational purposes. During the autumn of 1992 and 1993 surveys were done among the users of Oslomarka to collect information about the reasons for visiting a particular area, the main purpose of the visit to the forest, the attitude on how the forest is influenced by the management practices, and the willingness to pay for increased restrictions on the management practices. A main hypothesis to be tested was if there were any differences in responses among users of private forests, which were judged more intensively managed for timber production, and users of municipal forests which have been managed with explicit multiple-use objectives during the last twenty years. Minor differences in responses among users of private forests and users of municipal forests were found. Only the attitude toward a statement saying that passability is not much affected by twigs and branches from forest operations could support a hypothesis that the users of private forests are more discontent (see Table 4). A smaller share of respondents in private forest agreed to this statement compared with the respondents in municipal forests, and a larger share disagreed. In both subsamples relatively more respondents agreed with positive statements about landscape attributes caused by forest management and disagreed with negative statements. Yet, 60% of the respondents gave at least one answer to the 7 or 9 statements indicating a negative view toward one aspect of the current management practices. The majority of the users gave reasons for visiting the forest which are not unique for forest areas, like calm and relaxation, be together with friends/family and exercise (see Table 2). Easiest access was the reason most of the users gave for visiting the specific area (see Table 3). This reason varied significantly with answers indicating a welfare reduction if the area where the interview took place was assumed to be reallocated from forestry and closed for recreational purposes (see Table 5). Yet, it was not given a clear definition of the size of the area connected to this question. Mean willingness to pay (WTP) for more cautious management practices in the Oslomarka, through an environmental tax on wood-products, was estimated to NOK 286 per household per year in 1992 (open-ended question) and NOK 235 in 1993 (conditional mean of a dichotomous choice). The only sosioeconomic variables varying significantly with WTP in both surveys were age (-), and expressing a negative view about the landscape in the area on at least 3 of 7/9 statements (). The regression analysis performed on the WTP-data indicated a stronger theoretical validity for responses in the 1992-sample than the 1993-sample, since WTP in 1992 varied significantly and positively with gross household income.
