Trade-offs among intensive forestry, ecosystem services and biodiversity in boreal forests
DisciplineEkologia ja evoluutiobiologia
Finnish forests are used extensively for timber production but are also providers of other ecosystem services and harbor unique biodiversity. The ecosystem services approach has so far been used marginally in the context of Finnish forestry; however, due to the multiple values associated with Finnish forests and the impacts forestry operations have on forest ecosystems, it is clearly applicable in this context. In this thesis, I studied the occurrence and severity of trade-offs among ecosystem services and biodiversity conservation in Finnish forests. I used forest inventory data, forest growth simulations, and multi-objective optimization to reveal how the severity of the trade-offs varies among combinations of ecosystem services, across spatial scales, and across time, and how the trade-offs could be mitigated by forest management planning. Overall, the results showed that there are clear and challenging conflicts between intensive forestry and ecosystem services in Finland. Ecosystem services provided by forests were found to diminish when the forests were used intensively as a source of timber, whereas reducing or refraining from harvests maintained comparatively high levels of multiple non- timber services and biodiversity. Non-timber services and biodiversity were also shown to recover from intensive forestry the slower the longer intensive forestry was continued, suggesting that forestry’s negative impacts may be long-lasting. The use of optimization tools can help planners to identify management strategies that balance conflicting objectives as well as possible, especially if the analyses are conducted at large enough scales. However, the fact that there are trade-offs means that losses in some objectives are inevitable. It is left to forest managers and other stakeholders to consider which of these losses they are willing to accept. ...

Pohjanmies, Tähti; Eyvindson, Kyle; Triviño, María; Bengtsson, Jan; Mönkkönen, Mikko (Springer, 2021)There is ample evidence that intensive management of ecosystems causes declines in biodiversity as well as in multiple ecosystem services, i.e., in multifunctionality. However, less is known about the permanence and ...
Continuous cover forestry is a cost-efficient tool to increase multifunctionality of boreal production forests in Fennoscandia Peura, Maiju; Burgas Riera, Daniel; Eyvindson, Kyle; Repo, Anna; Mönkkönen, Mikko (Elsevier, 2017)Earlier research has suggested that the diversification of silvicultural strategies is a cost-efficient tool to ensure multifunctionality in production forests. This study compared the effects of continuous cover forestry ...

Management diversification increases habitat availability for multiple biodiversity indicator species in production forests Duflot, R.; Eyvindson, K.; Mönkkönen, M. (Springer Science and Business Media LLC, 2022)Context Forest biodiversity is closely linked to habitat heterogeneity, while forestry actions often cause habitat homogenization. Alternative approaches to even-aged management were developed to restore habitat heterogeneity ...
