Results summary

The short-term (1-8 years) effects of conservation thinning are
mainly positive or neutral for biodiversity. In several cases, responses in the taxa to cutting could not have been detected without our minimal intervention plots. In addition, species turnover was high also under minimal intervention. After 8-10 years, conservation thinning seems to favour regeneration of shrubs (e.g. Corylus, Rhamnus, Lonicera) rather than trees such as oaks – see our photo series. Planting of oak seedlings is one management possibility. While our results so far at least partly support non-traditional management, long-term data are needed to evaluate the management alternatives, including unpredictable events. We suggest that at least 30% of this kind of forest in the region should be reserved for minimal intervention.

Species effectsA summary of the effect of conservation thinning on the different species groups studied in the Swedish Oak Project. Plus means that the species group benefitted, plus/minus means no discernible or significant effect, minus means that the species group was disfavoured (although the negative effects have turned out to be small, and disappear with time). Note that timber harvesting may reduce the amount of dead wood in a forest in the long run, which could disfavour some species groups.
