Entrance to the hollow stone cave

The hollow stone cave is located in the Teutoburg Forest near Kohlstädt in the North Rhine-Westphalian district of Lippe and is a nature conservation and FFH area .

It was explored as early as 1779 as one of the most important caves in East Westphalia in the fissure system of marl limestone of the Upper Cretaceous (Turon, Lamarki layers). However, with a few exceptions, it is denied access to the public today, as it has been designated a natural monument and is a wintering area for bats .

Geographical location

The hollow stone cave is located in the southeast part of the Teutoburg Forest about 3 km southwest of the interface with the south-facing Egge Mountains . It is located around two kilometers east-northeast of Kohlstädt , a north-eastern district of the community in Schlangen in the south of Lippe . Its entrance is about 250 meters (as the crow flies ) west of the Hohlestein summit ( 433.2  m above sea  level ) at around 420  m above sea level. NN .

Brief description

The natural cleft cave , like the Lukenloch and the Bielstein cave on Bauernkamp, ​​was formed in the Plänerkalk. It has a total length of approx. 200 m. The greatest height is 47 meters. The entrance area is provided with a four meter high and 0.5 to 1.5 m wide grille and has a sloping, rubble-covered floor. A bottleneck after 30 m extends the cave into two chambers, which contain stalactite formations in the rear and hard-to-reach parts .

fauna

The well-preserved cave is particularly significant in terms of its valuable fauna . It is used by bats most of the year. So far the bat species bearded bat , brown long-eared bat , fringed bat , water bat , large mouse- eared bat and pond bat have been detected. With 35 animals the largest number of the great mouse-eared mouse has been counted in winter quarters. The entrance is barred to protect the cave and the bats from disturbance.

A special feature is the existence of the bat cave beetle ( Choleva septentrionis sokolowskii n. Ssp.), Which occurs as a special subspecies worldwide only in this one cave. As a larva and adult, it feeds on deceased bats, bat droppings and leftover food.
