Abstract
In Sweden one forestry method, the clear-cutting
method, has been used all over the country despite
differences in climate, topography etc. At present
there is a growing interest in using alternative
methods such as selective felling, which to a
larger extent mimic natural disturbances. In this
study we compare virgin forests with stands which
have been cut with old selective felling
(dimension felling), new selective felling (single
tree selection felling), and clear-cutting with
respect to frequency of characters important to
biodiversity (mainly dead wood). The frequency of
different types of dead wood decreases with
increasing intensity of the cutting method in the
following order: old selective felling, new
selective felling, and clear-cutting. New
selective felling had higher amounts and quality
of dead wood compared to clear-cutting. New
selective felling also showed less differences
compared to virgin forests than clear-cutting.
Dead wood in new selective felling compared to
clear-cutting may offer substrate for different
types of faunas because of the environment
surrounding the dead wood. Even if the new
selective felling method seems to provide higher
amounts of dead wood compared to the clear-cutting
method, further studies of organisms utilising the
dead wood are needed. New selective felling does
not seem to solve the problem of decreasing
availability of dead wood in managed forests and
there is still a need to preserve unmanaged forest
patches in a landscape perspective in order to
offer habitats with a high amount of dead wood. |
