EXECUTIVE SUMMARY - UNESCO World Heritage

decomposers of beech wood, is regularly
found on both living and freshly dead
trees.
Fauna
Serrahn is rich in insect species. MÖLLER
(in FLADE et al. 2003) found 428 xylobiotic
beetle species. With the moth Schiff ermuelleria
stroemella, a prim eval forest relic
species has been observed which does not
occur in Germany but in a very few isolated
cases (MÜLLER et al. 2005). Species
endangered at a supraregional level also
include the beetle Acritus minutus. Ampedus
hjorti, Nemapogon picarellus, Osmoderma
eremita, Pseudathous hirtus, Ptinus fur, and
Tenebrio opacus have been observed as
exclusive and signifi cant species indicative
of near-natural beech forests.
Th e Middle Spotted Woodpecker (Dendrocopos
medius) as an indicator of old beech
forests, the Black Woodpecker (Dryocopus
martius) as a key species for hole-nesting
birds, and cavernicolous insects (e.g. Aderidae)
are found in the nominated component part.
Th e population density of Eurasian Nuthatch
(Sitta europaea), a hallmark beech forest
species, is twice as frequently in the component
part which has not been managed
for fi ve decades, as in an old yet managed
reference forest (PRILL 1994) (tab. 2.8).
Among the bats, the Lesser and Common
Noctule (Nyctalus leisleri, N. noctula) as well
as the Barbastelle (Barbastella barbastellus)
have been observed as typical inhabi tants of
old and dead wood within the component
part.
