description

The nature reserve lies between Wolfsburg and Gifhorn. It encompasses the course of the Aller with its bank areas as well as adjacent areas between the A 39 near Wolfsburg and the Braunschweig – Wieren railway near Gifhorn. To the east of the A 39 bridge over the Aller, a nearly 1,700-meter-long section of the Aller canalized here is included in the nature reserve. Furthermore, southeast of Dannenbüttel, the Beverbach from the Bevermühle in the area of ​​the campsite on the Beversee to the confluence with the Aller is included in the nature reserve.

The Aller runs relatively close to nature in the nature reserve. It is not expanded below the highway bridge except for short sections and has unspoilt banks, various sedimentary structures with fine sand ingen, gritty and rough rocky areas and flood water vegetation with reflective pondweed , streaky pondweed , marsh water Star and other aquatic plants such. B. Simple Hedgehog Cob and Common Arrow Weed . Almost 30 species of fish have been identified in the Aller , including wolffish , brook lamprey , mud whip , bitterling , bleak , mildew , burbot , loach, pikeperch and pike . Furthermore, various live here mayflies , stone and caddis and the Oblate mussel.

Long stretches of the river's course are accompanied by moist tall herbaceous vegetation , in parts also by trees, and surrounded by extensive grassland , which is often followed by forest areas. These are partly characterized as rest of the alluvial forest and moist oak-hornbeam forests . The grasslands in the floodplain are made up of a mosaic of differently used areas. In addition to intensively used areas, there are hay meadows , nutrient-rich wet meadows , marsh marigold meadows, floodplain and transitions to lean grassland. The floodplain areas are subject to natural river dynamics and are flooded during floods. In the floodplain of the Aller you can find oxbow lakes of the river and flood troughs as well as still waters . The still waters are mostly near-natural with water float , diving leaf and floating leaf vegetation such. B. Frog Bite , Small Water Lily, Floating Pondweed and Yellow Nondock .

On the dune areas adjoining the floodplain , more or less narrow mixed oak forests with English oak grow widespread . In some cases, there are also commercial forests with pines , which are to be converted into near-natural forest communities in the course of their regeneration . In some places, there is also sandy grass here. Smaller areas on the higher areas are also used as fields . The area of ​​the former nature reserve "Dannenbütteler Torfteile" is characterized by a small, muddy dune valley. Swinging lawns with Schnabelried and various peat moss communities settle in former peat cuttings that have filled with water and slowly silt up .

The lowland landscape is the habitat of a species-rich fauna. Bat species such as water bat , fringed bat and brown long-eared bat are native to the nature reserve . Various dragonflies such as the banded demoiselle , common wedge damsel , green mermaid and blue feather dragonfly find a suitable habitat here. The moored areas of the Dannenbütteler Torfteile are the habitat of the Großer Moosjungfer . Still waters and wet meadow areas offer tree frog , moor frog , natterjack toad and crested newt a suitable habitat.

The nature reserve above Neuhaus is an important breeding bird area across the country. A species-rich avifauna is also native here. So live in different habitats u. a. Sperber , Honey Buzzard , Black Kite , Red Kite , black stork , white stork , middle spotted woodpecker , lesser spotted woodpecker , green woodpecker , gray woodpecker , oriole , nightingale , red-backed shrike , barred warbler , Meadow Pipit , Whinchat , Wagtail , Skylark , partridge and quail and the curlew .

The Aller also offers a suitable habitat for otters and beavers , which rely on floodplains with banks rich in softwood.
