Abstract

For a long time the primary aim of forestry in Sweden has been the production of timber, but in recent decades other functions, such as biodiversity, have been increasingly recognised by society. Sweden has ambitious goals for forest management, aimed at serving public interests, providing valuable timber yields and preserving biodiversity. Achieving the level of various goods that forests shall provide, under such goals, is thus rather complex. This thesis focuses on trade-offs between production of timber and the maintenance of biodiversity in forests, and the effects of information on benefits, costs and biological traits. In Paper I the benefit of forest land protection was estimated based on a nation wide contingent valuation survey. Paper II examined and compared, through survey data, the attitudes among private forest owners and forest officers. Papers III and IV used data from a field inventory in old growth forests (>110 years of age) of Norway spruce (Picea abies [L.] Karst.) in the county of Gävleborg, Sweden. In Paper III the relative importance of information about costs and biological traits in reserve selection was examined. In Paper IV the cost-efficiency of different strategies for setting aside forests, using different biodiversity targets, were analysed. The thesis revealed a positive willingness to pay for forest land protection among Swedish citizens, and also a positive attitude among private forest owners to biodiversity as well as timber production. The views of forest owners and forest officers did not always coincide. Moreover, the relative importance of including data on costs and conservation benefits depended on how the conservation goal of the reserve network was formulated. There was also a difference in cost-effectiveness between different nature conservation strategies and biodiversity targets. The results emphasise the importance of achieving cost-effective solutions in biodiversity conservation through the proper use of information about biological traits and costs, as well as considering values and attitudes held by different interest groups in society.
