The Kiehnmoor is a nature reserve in Germany. It was designated as a nature reserve in 1992. It has an area of 440 hectares (1,100 acres) of which 100 hectares (250 acres) lie in Celle district and 340 hectares (840 acres) in Uelzen district. The nature conservation authorities of these districts are responsible for the reserve. A large part of the area is wet meadow, that in places is intensively farmed. However the majority of the area has been left in its natural state. A small sand heath forms part of the reserve. Its southern perimeter borders immediately on the larger heathland area of the Südheide Nature Park. The Heidschnucken, moorland sheep characteristic of the region, are reared here. North of the Kiehnmoor and immediately adjacent to it is the valley of a partially dammed stream, the Gerdau, and the Brambosteler Moor nature reserve. To the southeast the reserve borders on the Unterlüß Firing Range (Schießplatz Unterlüß), belonging to the firm of Rheinmetall, and the Große Heide ("Large Heath") near Unterlüß, that is closed to the public. Kiehnmoor, too, is totally out-of-bounds. This whole area is very secluded. Rare birds have settled here including the crane and the black stork. Even the otter may be found here.
