The largest port in Scandinavia is growing. A new ro-ro and container terminal is due to be built beside the present ro-ro terminal at Arendal - the largest planned expansion initiative at the Port of Gothenburg since the 1970s.
On the site of the new terminal there are currently 1.7 hectares of eelgrass*. To ensure eelgrass volumes are maintained in the Gothenburg Archipelago, the Port of Gothenburg will plant the same amount of eelgrass at another location in the vicinity.
Edvard Molitor, Environmental Manager at Gothenburg Port Authority, emphasises the importance of eelgrass meadows to the ecosystem and as a spawning ground for several species of fish. “When we build the new terminal, the eelgrass meadows at the site will disappear. To compensate for this loss, we will replant the same volume of eelgrass that disappears from the bay at Arendal.”
Unfortunately, planting eelgrass is no easy task. The method that produces the best result is both expensive and time-consuming. One shoot at a time is planted by hand. It may be slow, but it is the approach research has shown works best.
Special conditions needed
After long preparations, eelgrass test plantings have now commenced in two locations just outside port area.
