Half a century of multiple anthropogenic stressors has altered northern forest understory plant communities
The boreal forests constitute the largest forest biome in the northern hemisphere. These forests are under increasing anthropogenic impact from intensified forest management, eutrophication and climate change, which may change their ecosystem functions and the services they provide. Swedish forests cover a long climatic gradient, receive highly variable rates of nitrogen deposition, and have a long history of forest use. Extensive systematic long-term data on vegetation from the National Forest Inventories (NFI) make Sweden an ideal area to study how species composition and function of other, more pristine boreal forests, might change under increased anthropogenic impact. We used NFI-data t…
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…
