Abstract [en]

In this case study of Swedish boreal forestry, we analyze the implementation in practical management of a sustainable forest management that includes the continued capacity of ecosystems to also provide non-timber services. In the Swedish national forest policy, the equal goals of timber production and biodiversity conservation have increased the responsibility of landowners and managers to modify practical management. We compiled written information from three larger FSC-certified forestry companies combined with semi-structured interviews with forest management personnel at regional offices to map what data and information the companies collect and use. We examined to what extent obtainable information from the forest companies captures composition, structure, and function of boreal ecosystems at patch, stand and landscape scale. This was done using 47 indicators compiled from literature and grouped into five categories based on nationally identified deficiencies in the managed boreal forest compared to unmanaged forest. We found that the recording of data describing different aspects of the forest ecosystem were separated in two largely uncoordinated systems, Ecological Landscape Plans and stand registers. While there is a need for conservation-oriented data across scales, collected statistics was largely production-oriented and related to the stand scale. We also identified information gaps regarding different ecosystem structures and their spatial distribution such as dead wood and habitat networks. The knowledge base available to future management decisions also seems to lack information on connectivity in the landscape, habitat at smaller spatial scales and the effectiveness of reserved areas. To reach the ecological goals of sustainable forest management, there is a need to further coordinate existing data and information but also to fill gaps in particular regarding cross-scale information.

Abstract [en]

Maintaining species diversity, ecosystem functioning, and socioeconomic values requires continued ecosystem heterogeneity across scales. This thesis aims to bridge gaps between ecological theory, environmental goals, and practical application of sustainable forest management needed to maintain such heterogeneity. Included case studies of boreal Sweden concern three challenges in the cross-scale understanding of heterogeneity: matrix qualities and composition; acquiring and incorporating historical information; and interactions between forest composition and management. Paper I cover three large-scale forest companies in four boreal counties today, outlining available information on matrix qualities and composition from the companies. Papers II-III cover the village scale from 1720s–1850s–present in Dalarna County and papers IV-V the parish scale from 1860s–present in the same county. Geographic Information Systems were used to integrate historical maps with present data, perform spatiotemporal analyses, and extract data for statistical testing in primarily generalized linear models. For the practical realization of sustainable forest management, the results indicate a need for further monitoring across scales to understand matrix composition, especially in relation to small voluntary reservations in a larger spatiotemporal perspective. Historical material can provide information on temporal connectivity and spatial separation between the past and present forest composition from analysis of change trajectories respectively interacting variables. This thesis suggests that models of forest dynamics are more relevant for local implementation of sustainable forest management efforts if including interactions between forest dynamics and ownership as an approximate driver of local change.
