The area is located within the natural landscape unit Ostbraunschweigisches Hügelland (East Brunswick Hills) in the natural geographic region of Boerden (Atlantic biogeographic region) in the Helmstedt district.
At the Treue surface mining, brown coal was mined in an area spanning 610ha from 1881 until 1993.
Since this time, the region has been gradually re-cultivated into agricultural, forest and biotope areas; the formation of an extensive residual water body was a welcome side-effect.
The original natural conditions at this site were essentially altered by the brown coal mining activities.
The actual project area covers a fallow area of neglected grassland, bush grass fields (Calamagrostis epigejos) and successional shrubbery.
The restoration of several silted-up water bodies in this area is one of the project's objectives.
Currently, the area is one of the key ranges for the European green toad in Lower Saxony.
Their population is, however, decreasing here as well. As an objective of the project, this decline is to be halted and the population of the European green toad is to be secured.
Area size: 7ha
