Binnendünen Nordoe, Nature reserve in Dägeling, Germany

Binnendünen Nordoe is a nature reserve in Schleswig-Holstein featuring inland dunes, dry meadows, heathland, and nutrient-poor water bodies across about 407 hectares. The landscape supports specialized plants and animals that depend on these harsh, infertile conditions.

Christian IV of Denmark used the area as a gathering place for Danish armies during the Thirty Years' War. In the German Empire the Prussian Army trained here, and later the Wehrmacht; the nearby Hanseaten-Kaserne in Itzehoe and Freiherr-von-Fritsch-Kaserne in Breitenburg also sent soldiers. The 407-hectare reserve was designated in 2013, with the ordinance dated 6 March 2013.

The reserve is managed by the Stiftung Naturschutz Schleswig-Holstein, which leases about 390 hectares. The foundation uses Galloway and Scottish Highland cattle, Exmoor ponies and Buren goats to graze the open land, preventing scrub encroachment and pushing back existing woody growth. Parts of the area also serve local recreation.

The reserve lies south of Itzehoe on the Münsterdorfer Geestinsel, spanning Dägeling, Kremperheide and Breitenburg. The Marschbahn line Elmshorn–Westerland/Tondern crosses the far northwest corner, and a siding for the Lägerdorf cement works and chalk pits crosses the northeast. Parts of the area serve local recreation; the Stiftung Naturschutz Schleswig-Holstein manages it and leases about 390 hectares.

The reserve is grazed by Galloway and Scottish Highland cattle, Exmoor ponies and Buren goats, not Boer goats; the mixed herds hold back scrub and push back existing woody growth. In 2017 and 2018 more than 2,300 young garlic and natterjack toads were released here, and twenty sand lizards were reintroduced in 2017.
