The objective for developing techniques for large-scale restoration is to help re-establish eelgrass to a much greater extent than is the case today.
Dense eelgrass meadows with high biodiversity provide important ecosystem services and ensure a good ecological status of coastal ecosystems. They play a critical role in stabilising the coastline through wave attenuation and increased sediment stability by roots and rhizomes. Furthermore, the high primary production and retention of particles make eelgrass meadows natural filters for nutrients and fine particles and thereby maintain high water clarity. They also provide other valuable ecosystem services, including carbon sequestration, fisheries, tourism, and recreation.
Restoration of eelgrass on a large scale can therefore be seen as an instrument to achieve a functional good ecosystem and can contribute to achieving the objectives of several EU directives such as the Water Framework Directive, Natura 2000
