The nature reserve Bruch von Gravenbruch (NSG identification 1438008) is located in the Offenbach district in Hesse . It covers approximately 93.47 hectares of forest. The purpose of the protection is to preserve the extensively used or fallow meadow areas with the surrounding natural forests, in particular quarry forests, as a habitat for the plant and animal communities with a high proportion of endangered species, which are determined by different levels of moisture.

With an identical layout, the nature reserve is also designated as FFH area DE-5918-304 NSG Bruch von Gravenbruch. This makes it part of the European Natura 2000 network of protected areas.

Area description

The nature reserve is located in an extensive forest area north of the L3117 state road east of Neu-Isenburg and west of the Gravenbruch district . The name Bruch is derived from swamp. It is a fen that took a good 300 years to form its current biotope structure. One of the special features is a high groundwater level. The numerous small bodies of water are important for the amphibian world. In 1984 the Gravenbruch quarry was designated as a nature reserve (NSG) by the Darmstadt regional council due to its high ecological value and after efforts by the city of Neu-Isenburg, the Hessian Society for Ornithology and Nature Conservation (HGON) and the Nature Conservation Union of Germany (NABU) .

Flora and fauna

Two of the enclosed meadow areas, the Eirundwiese and the Schönseewiese, are also of floristic interest. Around 200 plant species were identified in the NSG, 16 of which are on the red list. These include the endangered Hartman's sedge ( Carex hartmanii ), the thread sedge ( Carex lasiocarpa ) and the swamp hair strand ( Peucedanum palustre ). Other special species are swamp violet ( Viola palustris ), swamp blood-eye ( Comarum palustre ) and the common water hose ( Utricularia vulgaris ), which is an animal-catching plant. There are reptiles ( grass snake ), amphibians (agile frog and tree frog) as well as rare species of birds such as black woodpecker, red-backed shrimp, mistletoe and tree pipit.
