1. Habitat restoration aims to improve local habitat conditions for
threatened species. While such restorations are widespread, rigorous
evaluations of their success are rare. This is especially true of those
considering species dynamics. Increasingly, deadwood is a target for
forest restoration as many species directly and indirectly depend on this
resource. 2. In a broadleaf forest in southern Germany, we explored the
effect of landscape-wide deadwood restoration on the population genetic
structure of the specialist fungus-dwelling saproxylic beetle Bolitophagus
reticulatus. Before 2003, the northern area of this forest was intensively
logged for more than half a century, while the southern part was less
intensively managed. This drove populations of the host fungus Fomes
fomentarius, and consequently the beetle, to local extinction in the
northern part. Only after the first decade of restoration were both the
fungus and its beetles present across all areas of the forest. 3. Using 17
newly-developed microsatellite loci, we show that these beetles exhibit
population genetic structuring, mainly influenced by the north-south
divide. However, the low degree of isolation-by-distance, and the low
relatedness of beetles collected from the same trees or fungus, shows that
strong dispersal ability is facilitating the recolonization of these
forests on the scale of 10s km. In another ten years it is likely that the
population will show even less genetic structuring. 4. Synthesis and
applications. Through the recolonization of the fungus (Fomes fomentarius)
and the fungus-dwelling beetle (Bolitophagus reticulatus) after deadwood
restoration, we demonstrate that, while there are many discussions on the
optimal spatial distribution of deadwood, just the presence of deadwood
can be sufficient to enable recolonizations of specific species. As long
as some relict populations of these species are embedded in a once
intensively-managed forest, increased deadwood (amount and diversity)
anywhere will benefit recolonization of the habitat. However, increasing
deadwood diversity should also be encouraged to benefit even more species.
Zytynska et al. Bolitophagus dataBolitophagus reticulatus beetles were
collected from Fomes fomentarius fungal bodies, in the ‘Steigerwald’
forest area in southern Germany (Bavaria) (N 49° 50' 53 E 10°
29' 41), 2014-2015, across the three different scales (within-fungi,
within-tree, and among trees). Data gives geographic location, tree and
fungi ID and the multi-locus genotype of each beetles as identified from
17 newly-developed microsatellite loci.
