Bøyaøyri nature reserve
The Bøyaøyri became a nature reserve in 1991. It extends over a total area of 230,000 m², of which 94,000 m² are terrestrial.
The delta Bøyaøyri is situated in an area with brackish water, which means the water is a mixture of fresh water from the river and salt water from the fjord. River deltas are among the most productive ecosystems in Norway.
River deltas are also an endangered type of ecosystem. In Norway, they cover only small areas, but these are of great importance. River deltas serve among other things as resting and nesting areas for both migratory and non-migratory birds, and house various unusual or rare plant communities. Since river deltas are often located near human settlements, they are also especially vulnerable to human activities. In many of the fjordarms in Western Norway deltas have been converted into building land or agricultural land. Thus, they have more or less lost their value as a habitat for plants and animals.
Today, most of the Bøyaøyri still retains its original shape, with backwater areas and ouses. However, since the river's run-off into the fjord has been changed, the "old" part of the delta doesn't grow anymore. The sediments from the glacial river are now deposited further out in the fjord, where a new delta is building up.
In the nature reserve the following rules are in force:
All vegetation, in the water and on land, is protected and should not be damaged or destroyed. It is not allowed to introduce new plant species to the area.
All game, including sea mammals, and their dens, nests and eggs, are protected and should not be disturbed, damaged or destroyed. Hunting, trapping and the use of firearms are prohibited. Dogs must be on a lead. It is not allowed to introduce new animal species to the area.
All measures that lead to changes in the natural conditions are prohibited, e.g. construction of buildings, storage of boats, cars, caravans / trailers, laying of pipes, cables, wires or similar, road building, draining, removal or deposition of soil and stone material, levelling, pollution, deposition of waste and use of chemical agents.
Camping is prohibited. The use of camouflage tents in order to observe the birds is not allowed.
All motorised traffic on land and on the water is prohibited, as well as low-altitude flights below 300 m. This is also valid for model aeroplanes and boats. Windsurfing is prohibited.
In the nature reserve, all traffic is prohibited between 1 April and 1 August.
Altogether, 100 different bird species have been observed at the Bøyaøyri. 40-50 of these species are directly or indirectly dependent on wetlands, for example for breeding, finding food etc. Such species are Common Heron, Mallard, Common Teal, Eurasian Wigeon, European Oystercatcher, Purple Sandpiper, Dunlin and Ruff. Other species, such as European Starling, White Wagtail, Fieldfare, Redwing and Meadow Pipit are attracted by the wetlands, but are nesting in the adjacent areas.
The Bøyaøyri is of special importance for waterfowl and waders, first and foremost as a resting area during the migration period, but also as a wintering area. In spring and autumn, during the migration period, there can be numerous individuals of duck species like Mallard, Teal and Wigeon. In addition, Scaup, Common Scoter, Tufted Duck, Goldeneye and the rare species Common Pochard can be observed. Mallard, Teal and Red-brested merganser are nesting in the nature reserve.
The most common waders during the migration period are Oystercatcher, Lapwing, and Redshank, together with species like Curlew, Wood Sandpiper, Golden Plover and Snipe. Many of the waders stay at the Bøyaøyri only for a short time in spring and autumn, during migration, whereas Oystercatcher, Lapwing, Redshank, Common Sandpiper and Snipe nest in the nature reserve.
