Natural region D31 at a glance

The Weser-Aller-Flachland forms BfN major natural region D31. It extends as a broad lowland across central and eastern Lower Saxony between the Weser in the west and the Aller in the north and east, south of the Lüneburger Heide and north of the Niedersächsische Börden.

Geologically, glacial sands and Geest plateaus dominate. The soils are largely sandy, nutrient-poor and in many places influenced by groundwater. Between the Geest ridges run the broad lowlands of the Aller, Leine, Oker and Fuhse, which are still flooded across large areas at high water.

Ecologically significant are the river lowlands with wet grassland, oxbows and remnants of floodplain woodland, along with remains of the formerly widespread sandy heaths, acidic oak-birch woodland and mire sites. These habitats have declined sharply through drainage and intensification of use, and they are central to compensation planning.

For statutory nature conservation compensation the natural region is attractive, because sandy sites close to the groundwater table and narrow lowland parcels often deliver low yields. That is precisely where the potential for ecological enhancement is greatest, and precisely the kind of land greeNature secures for eco-accounts and project-related measures.

🌿 Ecological features

  • Broad lowlands of the Aller, Leine and Oker with wet grassland and regular flooding dynamics
  • Remnants of sandy heaths and inland dunes as nutrient-poor special sites
  • Acidic oak-birch woodland and pine plantations on the Geest plateaus
  • Remnants of fens and raised bogs with high restoration potential
  • Oxbows and flood hollows as spawning waters and resting habitats
  • Areas for meadow-breeding birds in the grassland lowlands close to the groundwater table

✅ greeNature in this region

We know the lower nature conservation authorities between Nienburg, Celle and Wolfsburg, and the practice of the Lower Saxony biotope value procedure. For projects in the Weser-Aller-Flachland we secure land true to the natural region in the lowlands and on the Geest sites, and we take on creation, management and documentation.

Compensation in D31

Typical measures in natural region D31

💧

Floodplain restoration on the Aller and Oker

Reconnection of oxbows, creation of flood hollows and removal of bank reinforcement. The restored flooding dynamics create spawning waters for amphibians and fish, as well as feeding areas for waders.

🌾

Grassland extensification in the lowlands

Conversion of intensively used lowland areas into species-rich wet grassland with late mowing and reduced fertilisation. Habitat for meadow-breeding birds such as northern lapwing, Eurasian curlew and common snipe.

🌿

Management of heath and sandy dry grassland

Scrub clearance, sod cutting and grazing on nutrient-poor sandy sites. The open, sunlit areas are habitat for thermophilic insects and reptiles and rank among the rarest biotope types of the natural region.

🐸

Small water bodies and amphibian habitats

Creation of new fish-free, sunlit standing waters with connected terrestrial habitat of deadwood and stone piles. Delivered as an advance CEF measure under § 44 BNatSchG for great crested newt and other amphibians.

🌳

New afforestation and forest conversion

Conversion of structurally poor pine plantations into site-appropriate oak-birch and beech mixed stands, plus new afforestation on marginal-yield sites. Both also count towards replacement afforestation under the state forest act.

🌳

Hedgerows and habitat network

Creation of hedgerows, field copses and margins in the cleared Geest farmland. They connect isolated habitats and provide stepping stones for grey partridge, brown hare and wild bees.

🐦

Northern lapwing and meadow-breeding birds

The grassland lowlands of the Aller and Leine are among the most important areas for meadow-breeding birds in Lower Saxony. Where impacts occur, the northern lapwing regularly depends on advance CEF measures such as scrapes, flood hollows and adapted mowing.

🐟

Kingfisher on running waters

Near-natural sections of the Aller, Oker and Fuhse with steep banks and clear water offer the kingfisher breeding sites. Where watercourses are modified, steep-bank modelling and bank restoration are the typical compensation measures.

About this species ›
🐸

Amphibians of the lowlands

Oxbows, flood hollows and extraction ponds are home to great crested newt, European tree frog and common spadefoot. All these species are strictly protected; impacts on their spawning waters require advance replacement waters within the spatial context.

About this species ›
🦎

Sand lizard on sandy sites

Railway embankments, sand pits and heath remnants in the natural region are typical sand lizard habitats. For construction projects, reptile exclusion fencing, translocation and a prepared replacement habitat with basking spots and egg-laying sites are standard.

Frequently asked questions

All about natural region D31

The Weser-Aller-Flachland is BfN major natural region D31 under the classification of the Federal Agency for Nature Conservation. It covers the sandy lowland of central and eastern Lower Saxony between the Weser and the Aller, roughly between Nienburg, Celle, Gifhorn, Wolfsburg and the Braunschweig area. The Lüneburger Heide adjoins to the north, the Niedersächsische Börden and the Nördliches Harzvorland to the south. The classification matters for compensation, because compensation measures need a spatial and functional link to the place of the impact.
Lower Saxony state law applies. Impact and compensation are assessed under the Lower Saxony implementing act to the Federal Nature Conservation Act and the biotope value procedure anchored in it. Each biotope type is assigned a value; the enhancement results from the difference between the starting and target condition multiplied by the area. For projects under federal responsibility, the BKompV may apply instead. Which procedure applies in a given case is determined by the competent lower nature conservation authority.
Well suited are lowland areas close to the groundwater table with weak yield capacity, intensively used grassland in the river floodplains, structurally poor pine plantations on the Geest plateaus, and former extraction sites. On such sites the gap between the starting condition and the achievable target condition is greatest, and so is the enhancement that can be achieved. Whether a specific area qualifies is something we assess on the basis of cadastral district, parcel, size and position within the natural region.
greeNature holds land in officially recognised eco-accounts in Lower Saxony and is continually developing new measure sites. Whether points from stock suit your project depends on the assessed requirement, the place of the impact and the requirements of the permitting authority. Tell us the requirement, the location and the timeframe, and we will check availability and come back to you with a concrete appraisal.
