Conservation value of low-productive forests measured as the amount and diversity of dead wood and saproxylic beetles
In many managed landscapes a major part of all remaining unmanaged land is low-productive. Low-productive land is also often over-represented within protected areas, as it is less expensive to set aside. Despite this the relationship between productivity and conservational value of a site is not well known, although it has been hypothesized that biodiversity generally increases with productivity due to higher resource abundance and heterogeneity. If biodiversity is indeed higher in more productive land, there is a risk that an important part of diversity will remain unprotected when mainly low-productive land is set aside. We examined the conservational value of low-productive forest land b…
The effects of logging residue extraction for energy on ecosystem services and biodiversity: a synthesis
This presentation is based on a paper in press in Journal of Environmental Management. We review the consequences for biodiversity and ecosystem services from the industrial-scale extraction of logging residues (tops, branches and stumps from harvested trees and small-diameter trees from thinnings) in managed forests. Logging residue extraction can be used in place of fossil fuels, and thus contribute to climate change mitigation. The additional biomass and nutrients removed, and soils and other structures disturbed, have several potential environmental impacts. To evaluate potential impacts on ecosystem services and biodiversity we reviewed 279 scientific papers that compared logging resid…
