Great section through the Harenniederung nature reserve

Danger! This section is not a bike path. So please push your bikes.

The nature reserve is in the west of Oldenburg. It includes a section of the lower reaches of the hair and the adjacent lowland areas. The Haaren is developed with predominantly steep banks. In some sections, the banks are fortified with fascines. The Haaren lowland is characterized by damp wasteland with tall herb meadows, swamps, vineyards and reed beds, in places with islands of wood and hedgerows. Parts of the lowlands are used extensively as grassland.

The nature reserve is the habitat of numerous plants and animals. Damp and wet meadows accommodate u. a. Marsh marigold, broad-leaved marsh orchid, overlooked marsh orchid, loosestrife, common rattle, yellow meadow rue, tubular water fennel, groundwort, marsh vetch, buckbean, millet sedge, thread rush and in places also needle marsh rush. Great sedge reeds are formed by slender sedge, swamp sedge, and two-rowed sedge. In addition, reeds, canary grass and water vapor reeds are developed. Tall herb corridors are z. B. from meadowsweet, loosestrife, loosestrife, yellow meadow rue, shaggy willowherb, angelica, bindweed, groundsel, common comfrey, real valerian and marsh ziest. The area is also home to the endangered swamp fern. The area includes Water rail, moorhen, kingfisher, tree sparrow, redstart, spotted flycatcher, green and lesser woodpecker are all native. Reed beds are a habitat for reed warblers, reed buntings and warblers. Also native to the area are grasshoppers such as the marsh cricket and saber-thorn cricket, and dragonflies such as the banded demoiselle, damsel-fly bat, spotted darter and damsel-eye. The area is also the habitat of various amphibians, including the marsh frog. Haaren and Haarenniehne are hunting habitats of the bat species serotine bat, water bat, common noctule bat, pipistrelle bat and common pipistrelle.

Floating aquatic vegetation settles in the Haaren, e.g. made of crested spawning herb, water star and yellow water lily. The Haaren is home to perch, ruff, gudgeon, roach, three-spined stickleback, wolffish, ide, bream, and occasionally eel, pike, dace, white bream, burbot, rudd and bitterling, as well as the mussel species pea and painter's mussel.

IiThe protected area includes the lower reaches of the Haaren and the adjacent lowland areas, which are characterized by high groundwater or backwater levels. A diverse flora and fauna has developed here, including some rare and endangered species and plant communities that are sensitive to changes in use and impairments to the water balance and are therefore particularly in need of protection.The lowland area, which is crossed by the typical, slow-flowing Haaren geest water, was previously used almost exclusively for grassland. Today, larger areas have fallen fallow and are developing from reed beds and sedge marshes to willow bushes and alder beech forest.nlwkn.niedersachsen.de/naturschutzgebiete/naturschutzgebiet-haarenniederung-189041.html
