Betydelsen av död ved för biologisk mångfald. Eninventering av vedlevande skalbaggar påSkillingaryds skjutfält 2016.

The military area Skillingaryds skjutfält is considered to harbor a great amount of value for saproxylic beetles, despite the fact that no inventory has been made, because of the high amount of dead wood. After the storms Gudrun (2005) and Per (2007) the County Administrative Board of Jönköping decided to leave a large amount of dead wood in the area to promote biodiversity. During the summer of 2016 the area was surveyed with window traps that were emptied three times. 121 species of saproxylic beetles belonging to 41 families were found during this time. Of these species there were three red listed: Uloma culinaris, Pseudanidorus pentatomus and Orchesia minor. Aside from the red listed species one species that indicate high nature values, Necydalis major, was found and four rare species from the genus Hylis sp. which are rare due to intense forestry. In comparison to other studies Skillingaryds skjutfält exhibit a less interesting fauna than expected. The reason for this is believed to be overgrowth, lack of variation and canopy closure that limits sun exposure. The summer of 2016 was quite mediocre in both temperature and sunny days which also may have affected the results. Since there hasn’t been any previous study of the saproxylic fauna in the area it is impossible to say if the windthrow from the big storms has affected the fauna in any direction. But since it is a known fact that storms generate dead wood it can be concluded that the increase of dead wood should have affected the fauna. This study is the start-up of a proposed continual survey and to draw any conclusions, comparison to other similar studies has been made. It should be emphasized that this study does not give the full picture of the saproxylic fauna and that there probably are more species living in the area than presented here.
