The nature reserve is located in Gifhorn. It comprises the course of the Aller river with its floodplain between the crossing through the Braunschweig – Wieren railway in the northeast and the crossing through the federal highway 4 in the west. In the downtown area of ​​Gifhorn it includes the river arm, also known as the Rotaller.

The Aller has mostly been straightened in the nature reserve. Except for the inner city area, the banks are unobstructed. In the west, two oxbow lakes of the Aller are included in the nature reserve. The floodplain of the river is predominantly occupied by grasslands in which woody plants are partially embedded. The grasslands are often used intensively. In addition, sedge and rush rich flood lawn and partly flow accompanying are Hochstaudenfluren to find. Riparian forest structures are only present in the northeast of the nature reserve . The Rotaller and the river Aller in the inner city area of ​​Gifhorn are mostly accompanied by trees. The undeveloped Aller valley floodplain is periodically flooded.

The area is the habitat of various plant and animal species, some of which are in need of protection and endangered, and serves to network the nature reserves above and below the protected area in the course of the Aller.

The Aller has partially flooding aquatic vegetation. It is home to hazel , gudgeon , chub , wolffish , burbot and barbel , among others, and provides a habitat for the dragonflies, common wedge damsel and green mermaid . The old arms of the Aller show the character of still waters with spawning and frog-bite communities. Here come z. B. Schlammpeitzger and bitterling before. The area is also a walking corridor and habitat for beavers and otters .

Moist tall herbaceous vegetation is formed by yellow meadow rue , true meadowsweet , water dost , common loosestrife and purple loosestrife . Extensively as hay meadow used grassland areas accommodate, among other yarrow , plantain and sorrel . Here are e.g. B. the butterflies multi-line leaf tensioner , black ribbon and light brown dust owl native.

The alluvial forest remains in the northeast of the protected area are characterized by alder and ash trees with a species-rich layer of shrubbery. Black alder , bird cherry and hazel , among others , grow here . In addition, there are hops , grass curls and reed grass . The area is home to otters and beavers .
