Læsø. 02/09/77; Region Norjylland; 66,548 ha; 57°12N 011°10E. Natura 2000 (SAC,SPA); Nature Conservation Areas, Scientific Reserve. The largest Danish tidal saltmarsh outside the Wadden Sea, with an outstanding botanical interest. The site, which includes open water, extensive mudflats, sand banks, heathland, islets, and areas of arable land, is an internationally important area for wintering, molting and staging waterbirds. Breeding mammals include seals (Phoca vitulina). The decline in grazing has led to vegetational succession in the saltmarsh. Invasive species are colonizing the site, especially Japanese Rose (Rosa rugosa). Scrub clearance has been implemented to re-establish open heathland and pastures. Human activities include recreation, horseback riding, horse wagon, guided tours and birdwatching. Ramsar site no. 149. Most recent RIS information: 2012.
