Seagrass planting will require the following pre-requisites and follow-ups: - A consolidated coarse sediment layer of approx. 20–30 cm thickness (engineered material), - An execution plan, prepared early enough to achieve the permit in time, - A permit by the authorities (STALU VP, WSA Ostsee), - Sufficient plant material: seagrass shoots (subject to availability, see details below) suitable for planting, - A harbor nearby (either Thiessow (8 km), Freest (11 km) or Lubmin (15 km)) shall be used for hand-over of seagrass shoots/geotextile ropes with seagrass from a Third Party supplier.
