Effects of forest-fuel harvesting on the amount of deadwood on clear-cuts
Forest residue left after clear-cutting is increasingly being used as biofuel in Sweden. Deadwood is an important habitat for many species and a crucial resource for forest biodiversity. On eight clear-cuts in eastern central Sweden, the amount of Picea abies (L.) Karst. deadwood left on the ground was compared with the amount collected in piles for fuelwood extraction. It was found that 65% of the volume, 77% of the surface area and 84% of the pieces of slash were to be extracted. In another study on 23 clear-cuts in the same region, it was found that 36% of the logs left outside piles after clear-cutting were later removed. These studies indicate that a considerable amount of potential substrate is lost during slash extraction.
