The area has been a nature reserve since November 14, 1936. At that time, the protected area was around 270 hectares in size, spread over around 190 hectares of the raised bog and around 80 hectares of the moor edge. In 1956 the scope of the Nature Conservation Ordinance was changed and the nature reserve was reduced to 193.2 hectares. Most recently, the Nature Conservation Ordinance was updated in 2016 (date of the ordinance: June 16, 2016). The size of the area was also adjusted from 193.2 hectares to around 196 hectares.

description

The nature reserve lies roughly between Nordhorn and Bad Bentheim . It provides a high moor area under protection, by drainage and peat is changed and partly strongly zerkuhlt. The moor is largely covered by moor forest, in which the downy birch dominates. Small areas has Bracken worked into the edge of clearings of the forest. In some cases, raised bog areas with cotton grass - peat moss - swinging lawns and Bult-Schlenken complexes have been preserved or released through decussing measures . In addition, there are moist moor heaths with beak reed communities as well as peat moss-rich and nutrient-poor, still waters that have arisen from former peat cuttings or that have been preserved as remains of heather ponds . The still waters only carry water year-round in the central area, while they dry out episodically in the peripheral areas. Your bank areas are partly held by Schnabel harrows taken ried, to which places areas with Tonquil connect. Reed and cattail also settle in the waters that do not have water all year round .

In central areas of the protected area, regeneration processes could be initiated in which living raised bogs slowly develop again. In the nature reserve settle bell heather , bog rosemary , Common Cranberry , Eriophorum angustifolium , sundew and other hochmoor typical and some endangered plant species, including purple moor grass , Parnassus , marsh St. John's wort , gentian , heath Zindel cabbage and pilularia globulifera . In the still waters settle u. a. Strandling , pure white water crowfoot and water lobelia . The nature reserve is also the habitat of a species-rich fauna. So here is u. a. the moor frog is native, as well as the butterfly species large meadow bird , blue gentian and high moor ground owl . The avifauna is u. a. represented by crane , corn and marsh harrier , short-eared owl , red-backed killer and goat milker . During the bird migration here raced Hobby , Common Snipe , Jack Snipe , Green Sandpiper , teal , teal , shoveler , oriole , Shrike and Stonechat .

The nature reserve is surrounded by an approximately 250 hectare, extensively managed grassland belt. The moor drains through various ditches in a westerly direction to the Rammelbecke, a tributary of the Dinkel , and in an easterly direction to the Hestruper Bach, which later flows into the Vechte .
