One is the expansive Allermörder Marsch characterized by open grassland. The other is the former Billwerder railway embankment. This embankment served a dual purpose acting as a secondary flood defense line.
The Allermörder Wiesen are a testament to restoration. Extensive conservation measures undertaken since the 1990s have revitalized the area. The ditch system running through the marshes has been restored spanning a total length of 20 kilometers. Water levels were raised with the help of wind pumps. This careful management has greatly improved the area’s biodiversity. The Allermörder Wiesen are now home to a rich variety of plant and animal life.
The Allermörder Wiesen are a birdwatcher’s paradise. Species like the lapwing redshank and common snipe thrive here. Many of these birds are rare in the Hamburg region. These birds nest in the sparsely vegetated grasslands. The creation of small bodies of water further enhanced their habitat. This also led to the return of other species such as the common curlew and ruff. The Allermörder Wiesen are considered one of the areas with the highest density of meadow birds in Hamburg.

Approximately 80% of the area’s plant species are found along the ditches. Over 87% of the endangered plant species are concentrated there too. An impressive 56 endangered plant species have been identified. The ditches’ vegetation ranges from fen vegetation to tall herb vegetation and even dry-lean areas.
