forest management and dead wood characteristics Doctoral dissertation ISSN 1652-6880, ISBN 91-576-7115-X Forest management has altered the age structure, tree species composition and dead wood availability of Swedish boreal forests. As a consequence, many saproxylic (wood living) insect species have decreased in abundance and many species are threatened. New conservation-oriented forestry uses management measures to favour saproxylic species in managed forests. In my thesis, I evaluated the importance of these measures for saproxylic beetles and possible improvements by using a large-scale field experiment at ten sites in northern Sweden. The substrate types used in the experiment included burned and shaded logs, logs inoculated with two species of wood-decaying fungi, untreated control logs, created snags and the tops of the snags. The experiment was performed in three stand types: clear-cuts, mature managed stands and old-growth stands. Additionally, I performed attraction experiments to examine the attraction of saproxylic beetles to sporocarps and mycelia-infected wood of wood-decaying fungi in landscapes with different proportions of
