Like on land, we need transformative change in how the seas are used to allow natural processes to recover. Moving on from species and habitats, there is an increasing recognition that marine recovery has to happen at ‘seascape’ scale.
Active restoration efforts are costly. Breeding, transporting and reintroducing species, and manually planting seagrass is expensive work. Costs are higher than on land as scuba equipment, trained divers and expensive safety gear are essential.
For this reason, rewilding offers an excellent approach to restoring the seas. Letting nature lead and intervening only when needed means that the costs involved in nature recovery are kept to realistic values.
Click on each icon below to learn more about how, in the sea, rewilding at seascape scale can mean combining the following.
First, using approaches that make space for nature to recover, using Marine Protected Areas or Other Effective Conservation Measures.
Reintroductions and restoration, particularly of species that can restore natural processes and have impacts through the ecosystem. This could include bringing oysters and seagrass meadows back into selected areas, which will in turn attract other marine species to the area.
Removing pressures, such as pollution, by regulating the use of the sea by people within and around the seascape.
Restoring connections between oceans and seas with inner coastal seas, e.g. by mitigating barriers such as dykes and dams.to help fish migration and breeding, and to restore the flow of nutrients from the rivers to the seas.
