- P>1. Forest reserves are established to preserve biodiversity, and to maintain natural functions and processes. Today there is heightened focus on old-growth stages, with less attention given to early successional stages. The biodiversity potential of younger forests has been overlooked, and the cost-effectiveness of incorporating different age classes in reserve networks has not yet been studied.2. We performed a reserve selection analysis in boreal Sweden using the Swedish National Forest Inventory plots. Seventeen structural variables were used as biodiversity indicators, and the cost of protecting each plot as a reserve was assessed using the Heureka system. A goal programming approach was applied, which allowed inclusion of several objectives and avoided a situation in which common indicators affected the result more than rare ones. The model was limited either by budget or area.3. All biodiversity indicators were found in all age classes, with more than half having the highest values in ages >= 100 years. Several large-tree indicators and all deadwood indicators had higher values in forests 0-14 years than in forests 15-69 years.4. It was most cost-effective to protect a large proportion of young forests since they generally have a lower net present value compared to older forests, but still contain structures of importance for biodiversity. However, it was more area-effective to protect a large proportion of old forests since they have a higher biodiversity potential per area.5. The geographical distribution of reserves selected with the budget-constrained model was strongly biassed towards the north-western section of boreal Sweden, with a large proportion of young forest, whereas the area-constrained model focussed on the south-eastern section, with dominance by the oldest age class.6. Synthesis and applications. We show that young forests with large amounts of structures important to biodiversity such as dead wood and remnant trees are cheap and cost-efficient to protect. This suggests that reserve networks should incorporate sites with high habitat quality of different forest ages. Since young forests are generally neglected in conservation, our approach is of interest also to other forest biomes where biodiversity is adapted to disturbance regimes resulting in open, early successional stages.

Factors Influencing the Choice of Management Strategy among Small-Scale Private Forest Owners in Sweden

Tidskriftsartikel (refereegranskat)abstract
- Half of the productive forest area in Sweden is owned by small-scale private forest owners. However, there is a lack of comprehensive information that would allow categorizing small-scale private forest owners according to their management strategy. In this study, we surveyed small-scale private forest owners in Sweden to determine the proportions who applied various management strategies. We analyzed the results using chi-square tests to identify the most relevant factors affecting the management strategy choices of individual forest owners. We found that. soft. factors, such as the importance of income from the forest, membership in a forest owners' association, certification and an interest in and knowledge of forestry issues, had a stronger impact on the choice of management strategy than most. hard. factors related to the owner or the property, such as gender and distance between the owner's residence and the property. However, property size was the most important factor and was associated with the importance of income derived from the forest and several other soft factors.

Krav på beslutsstöd för deltagande och konflikthantering vid skoglig planering
- 2010
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Denna rapport avser att, utifrån erfarenheter kring skogliga konflikter och intressemotsättningar, belysa vad ett beslutsstödssystem kan behöva ha för egenskaper. Erfarenheterna bygger i allt väsentligt på arbete som utförts inom ramen för projektet ”Konflikthantering i skogar med hög nyttjandetäthet” som finansierats av Skogssällskapet.
