Raahe elago archip -area 00 Natura 20


Natura 2000 area The archipelago off the Raahe coast has been chosen to be a part of the Natura 2000 network based on its bird fauna, vegetation and habitats. The total area is 2,240 hectares, which consists of about 358.5 hectares of land area and shallows, and about 1,881.5 hectares of water. The Raahe archipelago is the only significant archipelago in the Gulf of Bothnia between Rahja in the municipality of Kalajoki and Oulunsalo. The archipelago includes both forested inner islands near the shore and small, open islets further out to sea. The archipelago forms a scenically valuable entity, shaped by early means of livelihood such as cattle herding, fishing and maritime transport.

In order to secure successful bird breeding, the most important bird islets and islands are subject to a landing prohibition during the breeding season. The landing prohibition is in effect between 15 April and 15 July on the following islands: Saapaskari, Kakkonen, Selkämatala, Kallanriutta, Rääpäkänriutta,Vesimatala, Isokivi, Kurikka, Kusiini, Kanttikivet 1 May to 20 July: landing prohibition on Rääpäkkä. 1 May to 15 July: landing prohibition on Jyry.

Natural conditions

The islands of the Raahe archipelago are rather flat, consisting of moraine, rocks, gravel and sand. Strong land elevation is typical for the area, visibly shaping and forming the terrain and the landscape even during a person’s lifetime.

Vegetation There are several rare and endangered plant species on the Raahe archipelago. The majority of the land area consists of important Natura 2000 habitats, which is an indication of the importance of the area. Priority habitats occurring in the Natura 2000 area of the Raahe archipelago are: natural forests in a primary succession phase on the land elevation coast, sea shore meadows, coastal lagoons (gloe lakes and flads) and species-rich dry and fresh meadows. The magnitude of the land elevation phenomenon and the low-laying terrain of the shores lead to a rapid change in the vegetation. Moving towards land, the meadow shore usually turns into a bush zone and then into a rising, often grove-like and lush broadleaf forest zone. The vegetation on the outermost islets of the archipelago is scarce and short, consisting of grasses in a pioneer phase and bush-like alders. There are forests only on the largest

Raahe archipelago have disappeared, but new sites have also been found. The rise in the nutrient concentration of the seawater has also played a part in the overgrowth development. The high-rising seawater fertilises the shore meadows, which has caused the vegetation on the shores to become eutrophic. Eutrophication problems occur particularly in low coastal areas, near the coastline, on the archipelago and next to industrial facilities and urban areas. In recent years, the changes in vegetation on the Raahe archipelago have been especially prominent on the bird islets ‒ willows, birches and rowans have spread onto the bird islets. Herbaceous vegetation has also increased significantly in recent years. In addition to plants, the Raahe archipelago is home to endangered mushroom and moss species and other locally valuable fungal findings, mainly Polyporaceae fungi. Species such as Dichomitus campestris and Fomes fomentarius (tinder fungus) occur on the Natura area

The islands and the shore area Thanks to its proximity and easy accessibility, the Raahe archipelago offers plenty of opportunities for recreational use in summer and winter. The islands are well suited for boating and canoeing trips, and many of them are relatively easily to land on with a boat. The area is also great for picking berries and mushrooms in accordance with Finland’s everyman’s rights. During winter, when the ice is strong enough, many people enjoy skiing, walking or skating on the ice and the islands. The recreational use of the Raahe archipelago is managed so that the most valuable parts of the Natura 2000 area wildlife are not disturbed. Islands suitable for recreational use are Ämmä-Äijä, Iso-Kraaseli, Kalla, Konikari, Tasku, Ulkopauha and Smitti.
