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. |
