Aquatic warblers and alluvial meadows

Funding priority

Sustaining species diversity: reintroducing and protecting highly endangered species

Brief description

The project objective is to develop, as a model project, at least 200 ha of habitat for the aquatic warbler (Acrocephalus paludicola) by improving the hydrological regime and establishing rotating grassland cultivation in part of the Lower Oder Valley National Park (Polder 5/6). The site is intended as an ecological stepping stone to a neighbouring aquatic warbler breeding ground in Poland.

  • Conserving and nurturing the characteristic floodplain mosaic as a habitat for meadow birds (aquatic warbler, corncrake and common redshank) and alluvial Cnidium meadows using flexible/rotating cultivation with an adapted mowing schedule, corncrake-friendly mowing with refuge strips, establishment of new alluvial Cnidium meadows
  • Cost appraisal and assessment/development of funding models for adapted grassland cultivation to ensure beyond the lifetime of the project that the necessary measures for adapted grassland cultivation are applied in the Lower Oder Valley and other Special Protected Areas (SPAs)

The project is of critical importance in stabilising the last breeding population of the aquatic warbler in Germany. It is also the first step in implementing the management plan compiled in 2010 for the aquatic warbler in Brandenburg.

In supporting research by the University of Greifswald, the outcomes will be evaluated during the period 2012 to 2015 and recommendations developed for further action to secure the aquatic warbler population.
