The article cites a study which examines the spatial occurrence of the beetle, Harminius undulatos in Sweden. It has first analyzed the beetle's occupancy pattern relative to the stand characteristics and the amounts of present and past habitat in the surrounding landscape. It utilized a metapopulation model to predict the probability of occurrence in each forest stand. It has investigated that the dead wood dependent organisms should include habitat dynamics. It has presented that an estimated 82% of the landscape-wide recruitment took place in managed stands which covered 87% of the forest area compared with the 18% in unmanaged stand which covered 13% of the forest area.
