Stellmoor – Ahrensburger Tunneltal is a nature reserve in the Schleswig-Holstein city ​​of Ahrensburg in the Stormarn district .

The approximately 339  hectare nature reserve is registered under number 95 in the directory of nature reserves of the Ministry of Agriculture, Environment and Rural Areas. It was expelled in 1982 (date of regulation: August 16, 1982). The nature reserve is largely part of the fauna-flora-habitat area "Kammolchgebiet Höltigbaum / Stellmoor". The responsible lower nature conservation authority is the Stormarn district.

The nature reserve is located in the south of Ahrensburg. It protects a glacial channel that was created during the Glaciation of the Vistula and extends over a length of around seven kilometers from Ahrensburg to the Hamburg district of Rahlstedt . The part of the tunnel valley located in Hamburg is designated as a nature reserve " Stellmoorer Tunneltal ".

The nature reserve, which consists of three sub-areas, borders the Lübeck – Hamburg railway line to the west and the Hamburger Hochbahn underground line ( Walddörferbahn ) to the north . In the east and south-east, the nature reserve borders directly on the Ahrensburg residential area. In several places it is crossed by roads.

The protected area includes the humid valley of the Hopfenbach with accompanying swamp forests , ponds , reeds and raised bog remains. Forests grow on the ridges of the Geest . Sand ridges in the moored lowland are also taken up by grasslands . In addition, agricultural areas can be found in the nature reserve. The two sub-areas “Brauner Hirsch” and “Dänenteich” are located in a south-easterly direction outside the actual valley area. They establish a connection to the Feldmark.

In the damp areas with their quarry forests, which can be found particularly in the northern area of ​​the nature reserve, willows , alders , birches and grape churches predominate. Also sedges , ferns and peat moss to grow here as well as Viola palustris , Marsh Cinquefoil , Lysimachia Thyrsiflora , Bogbean and Small valerian . The humid areas are habitat for dragonflies such as the lunar damsel , the great king dragonfly and the little pitch dragonfly . Also amphibians find a suitable habitat, including frog , moor frog , common toad and spadefoot . The crested newt is common in the nature reserve. The swamp forests are also habitat for cranes . The reed zones are the habitat for the Marsh Harrier .

In the southern area of ​​the nature reserve there is wet grassland . Here come cuckoo flower , marsh marigold , the ragged robin , marsh trident , swamp yarrow and loosestrife before. Sometimes hedges with pollarded willows can be found, which u. a. provide nesting opportunities for birds nesting in caves and niches. The meadows are the habitat for lapwing , snipe and corncrake . The white stork uses the area for foraging.

The Hagen forest, a forest area that was used intensively for forestry in the past, stands on a ridge of the Geest that borders the tunnel valley to the east. In particular after the Second World War, the forest was often reforested with conifers , which led to a forest community that was remote from the location. In the meantime, the forest is being converted back into a deciduous mixed forest that is appropriate to the location, with pedunculate oak and birch forests and beech and oak forests, and old and dead wood is left in the forest. Old oaks and beeches have been preserved on the slopes to the tunnel valley and on the slopes of side valleys. They provide habitat for non-ferrous metals , small and black woodpeckers , ravens and Sperber . Also, bats and various amphibians and reptiles are found here.

Stellmoor and Ahrensburg Tunneltal are also significant archaeological sites. Several hiking trails run through the nature reserve . On the Alfred Rust hiking trail, named after the archaeologist Alfred Rust , there are several information boards on the geology, the natural environment and the archaeological importance of the area. The nature reserve is looked after by the Jordsand association for the protection of sea birds and nature .
