More conservation-oriented forest management practices have been implemented recently in the Nordic countries The goal of this ecological forest landscape management is to reconcile the commercial harvesting of boreal forests with biodiversity conservation Management aims at maintaining viable populations of the full array of naturally occurring species in an area while still keeping the timber flow as maximal as possible Basic ecological tools of managing landscape for biodiversity are (1) to mimic natural disturbance regimes, (2) to set aside areas in permanent or temporary nature reserves, and (3) to enhance dispersal of organisms by creating habitat corridors and stepping stones The ecological basis of this management system is not well founded, and much more empirical and theoretical research is needed to justify and further develop forest landscape management It has also proved difficult to assess the economic consequences of more conservation-oriented forest management because the market economy largely fails to give value to forest products other than fibre Considerable methodological development in the valuation of non-timber goods has occurred in recent years, but there is still much controversy over the justification of the valuation procedure in principle It seems that both economic and moral approaches to the issue of valuation are inseparable from the choices and decisions we have to make about ecological systems Perhaps the most fruitful outcome can be achieved by using moral and economic arguments in parallelread more

Long‐Term Effects of Forestry on Birds of the Eastern Canadian Boreal Forests: a Comparison with Fennoscandia
TL;DR: In this paper, the authors used life-history traits from habitat, nesting site, and geographical range to calculate an index of sensitivity to changes induced by modern forestry for boreal species of each region and provided an assessment of the long-term effects of forestry on eastern Canadian birds of the boreal forest.

Are fragments islands? Landscape context and density-area relationships in boreal forest birds.
TL;DR: Forest fragments do not function as true islands as the result of compensatory effects of the surrounding matrix in terms of availability of resources and enhanced connectivity (matrix quality hypothesis), and the characteristics of the habitat matrix should be explicitly incorporated into the assessment of species' responses to habitat fragmentation.

Alternative harvesting methods and boreal carabid beetles (Coleoptera, Carabidae)
TL;DR: The authors studied carabid-beetle assemblages in boreal spruce-forest stands representing early secondary succession, produced by three different logging methods, in central Finland in 1995-1998.

Co-variation and indicators of species diversity: Can richness of forest-dwelling species be predicted in northern boreal forests?
TL;DR: The data show that there is probably not a single taxonomic or forest structural characteristic to be used as a general biodiversity indicator or surrogate for all the species, and the results support the view that different indicators shall be used for different forest types and taxonomic groups.

TL;DR: In this paper, the authors have estimated the current economic value of 17 ecosystem services for 16 biomes, based on published studies and a few original calculations, for the entire biosphere, the value (most of which is outside the market) is estimated to be in the range of US$16-54 trillion (10^(12)) per year, with an average of US $33 trillion per year.

Species Diversity in Space and Time
TL;DR: In this article, the authors present a hierarchical dynamic puzzle to understand the relationship between habitat diversity and species diversity and the evolution of the relationships between habitats diversity and diversity in evolutionary time.

Effects of habitat fragmentation on birds and mammals in landscapes with different proportions of suitable habitat: a review
TL;DR: Simulations of patterns and geometry of landscapes with decreasing proportion of the suitable habitat give rise to the prediction that the effect of habitat fragmentation on e.g. population size of a species would be primarily through habitat loss in landscape with a high proportion of suitable habitat.

The Role of Riparian Corridors in Maintaining Regional Biodiversity
TL;DR: It is argued that riparian corridors should play an essential role in water and landscape planning, in the restoration of aquatic systems, and in catalyzing institutional and societal cooperation for these efforts.
