Stubbrytning - ett hot mot vedskalbaggar?

Abstract

Stump harvest after clear felling is a new method to extract bioenergy from the forest. However, removing coarse dead wood from the forest landscape might be in conflict with preserving the saproxylic (wood-living) biodiversity. This paper summarizes results from research investigating what effect we can expect on wood-living beetles. Species lists from 10 studies comprising a total of 549 beetle species were compiled. Of these species, 320 were classified as saproxylic. In spruce stumps the studies detected 44% of the Swedish saproxylic beetle fauna that has been categorized as ”living in spruce wood”. However, deciduous stumps seem richer in red-listed species. Some species associated with sun-exposed wood have a large proportion of their populations in clear-felling stumps. This indicates that a large-scale removal of the stumps will potentially threaten many species. The present focus to target spruce at stumps harvest, is well motivated from the saproxylic beetles’ view.
