At the end of 2023 the first joint management plan for the transnational World Heritage Site of High Coast/Kvarken Archipelago was finalised. The plan ensures the safeguarding of World Heritage values of the place and sets a shared direction for the managing the World Heritage Site in both Finland and Sweden. 

The management for the World Heritage Site is mainly done by the County Administrative Board of Västernorrland for the High Coast in Sweden. Metsähallitus Parks and Wildlife in Finland is responsible for the management of Kvarken Archipelago. Both organizations have their own site managers, who jointly authored the management plan. 

The plan ensures that a good and effective management can continue even when key personnel is changed or moves on to different positions. A lot of work has been done to use the SOUV as a basis for the identification, classification and evaluation of attributes. The management plan has been prepared without additional external help and without project financing.
