Natural variability of forests as a reference for restoring and managing biological diversity in boreal Fennoscandia

TL;DR: To restore some of the essential characteristics of the natural forest’s multiscale heterogeneity, diversification of silvicultural and harvesting treatments, as guided by natural disturbance dynamics, is needed to produce more variation in disturbance severity, quality, extent, and repeatability.

Abstract: In Fennoscandia, use of the natural forest as a reference for restoration and management of forest biodiversity has been widely accepted. However, limited understanding of the structure and dynamics of the natural forest has hampered the applications of the natural variability approach. This is especially the case in areas, where the natural forests have almost totally vanished. This review was motivated by the idea that despite these diffi culties the essential features of the natural forest can be reconstructed based on biological archives, historical documents, research done in adjacent natural areas, and modeling. First, a conceptual framework for analyzing the relationship between forest structure, dynamics and biodiversity is presented. Second, the current understanding of the structure and dynamics of natural forests at different spatiotemporal scales in boreal Fennoscandia is reviewed. Third, the implications of this knowledge, and gaps in knowledge, on research and on practical restoration and management methods aimed at forest biodiversity conservation are discussed. In conclusion, naturally dynamic forest landscapes are complex, multiscaled hierarchical systems. Current forest management methods create disturbance and successional dynamics that are strongly scale-limited when compared with the natural forest. To restore some of the essential characteristics of the natural forest’s multiscale heterogeneity, diversifi cation of silvicultural and harvesting treatments, as guided by natural disturbance dynamics, is needed to produce more variation in disturbance severity, quality, extent, and repeatability.

TL;DR: In this article, the authors synthesize the natural history and conservation needs of wood-inhabiting organisms and present management options for protecting and maintaining the diversity of these species in forests as well as in agricultural landscapes and urban parks.

Understory vegetation as a forest ecosystem driver: evidence from the northern Swedish boreal forest
TL;DR: In this paper, the authors highlight the ecological importance of understory vegetation, both in the short term by influencing tree seedling regeneration, and in the longer term by affecting belowground processes such as decomposition, nutrient flow, and buildup of soil nutrients.

TL;DR: In this paper, the authors consider the dynamics of populations in patchy environments, especially metapopulation persistence in the face of local extinctions, and determine whether these conditions are likely to hold.

Spatial and temporal variation in lightning ignitions in Sweden
TL;DR: In this article, fire statistics revealed that there are steep gradients in the distribution of lightning-caused fire ignitions in Sweden and the highest ignition density was found in the southeastern provinces of Kalmar and Osterg6tland, ca. 0.23/10 000 ha/yr.

A Model of Competition Incorporating Plasticity through Modular Foliage and Crown Development
TL;DR: In this paper, the authors use modular autonomy to incorporate plasticity in plant growth under competition and show that asymmetrical crown development, one form of plasticity, is advantageous to stand productivity and becomes more advantageous as the degree of spatial aggregation in the initial spacing of trees increases.
