Purpose

According to Landbrugsstyrelsen (the Danish Agricultural Agency), the purpose is to improve the aquatic environment in lakes by reducing phosphorus discharges. Phosphorus wetlands are located upstream of lakes where phosphorus reduction measures are needed.

Funding and pathways

Who can apply?

Municipalities and Naturstyrelsen (the Danish Nature Agency) can apply for grants for phosphorus wetlands. The measure is not open to private applicants.

What should be documented?

  • Land use and vegetation before the project.
  • Watercourses and ditches that channel water into the lake.
  • Terrain and depressions identified in the elevation model.
  • Changes after construction, recorded from the same locations.
