Shallow bays and reed beds are very important for a large number of plants, insects and birds and especially for fish that are completely dependent on these areas for their reproduction. Dredging and the clearing of reed beds may disturb the ecological balance in the area. However, the situation must always be assessed based on the special conditions and needs of each site. In some cases, the clearing of reed beds (especially dense ones) is a good measure that improves the conditions for the reproduction of fish. However, fish also need reed beds for shelter. Reed beds are also important habitats for birds and other organisms.
The Government of Åland must, in cooperation with other concerned actors, identify biologically valuable bays, species and habitats. At the same time, the possibility of simplifying legislation further with respect to less valuable areas, such as marinas, is being explored. First and foremost, the measure seeks to maintain the conditions for the existence of organisms in those bays which accommodate important underwater plants and animals. In these particularly important bays, even a small operation (less than 50 square metres) can have major adverse effects on underwater plants and animals. It is important to preserve known existing habitats to avoid biodiversity loss.
Objective of the measure:
The conservation status of native species in the Baltic Sea area must be favourable and their conservation must be secured in the long term. Harmful substances may not have any adverse effects on the functioning of the marine ecosystem or on the use of fish or game as food. At the moment, inventories of the underwater environment are being carried out and legislation is being revised.
