The birdlife in Vindelfjällen Nature Reserve has attracted attention for over fifty years. The area’s diversity and wealth of mires, deltas, lakes, streams and rivers provide good opportunities for breeding birds. The mountain landscape also enables exciting possibilities for studying migratory birds. The Ammarnäs Delta is a classic migratory bird site, with, for example, large flocks of red-necked phalaropes. Less widely known is the early spring migration of passerines through the mountain valleys in an easterly direction from Norway. Robins and pied wagtails, among other species, are noted in Vindelådalen at the same time as the first observations of these species are made in southern Sweden.
From the 1950s until the 1970s, the River Vindelälv, Lake Tärnasjö and other areas were under threat from being exploited for hydro-electric power. The discussions surrounding the possible regulation of the River Vindelälv demanded a need for more facts, and the LUVRE project was started in 1963. Since then, the area’s bird fauna has been systematically censused each summer by enthusiastic ornithologists and scientists. After more than forty years’ research, dedicated ornithologists still gather in Ammarnäs each summer. Ornithological research in Vindelfjällen has contributed greatly to the protection of the reserve.
All this research and censusing in Ammarnäs and Vindelfjällen has attracted a great deal of attention. Bird sites such as the deltas at Ammarnäs and Hemavan, Marsivagge, Lake Tärnasjö, the forests around Lake Tjulträsk and the alpine heaths on Mount Björkfjäll are now renowned among Sweden’s ornithologists.
