Germination success experiment of grey dune species

Marram grass is commonly used to revegetate open patches in coastal dunes. However, when open patches occur in regions without sand accumulation, planted marram grass does not grow well. Possibly, grey dune species can be sown directly on these open patches.

Different grey dune species will be sown in a greenhouse on three different types of soil collected from natural dunes (white dune, young grey dune, old grey dune). Different management practices will be tested and germination success will be monitored.

• Around 4 species for which seeds are commercially available
• 3 types of dune soil collected from natural dunes on one of the East Frisian Islands
• Different management options (such as covering the seeds with soil or leaving them uncovered)
