Pressure/threats to key biodiversity
Recent information (March 1998) indicates that all known threats to Swidwie lake have been removed. Previously these had been (1) drainage in the surrounding area in 1976 (40% of water supply lost), (2) agricultural effluent, which had been causing strong nutrient pollution of the lake, and (3) hunting in the surrounding area, which had been disturbing birds within the site. An EU-funded project being implemented in the area involves replacing the water lost in 1976. The new water supply will be stored at Zurawie reservoir, south of the lake, and cleaned there. According to the Nature Conservancy Officer hunting has also been stopped in the surrounding area.
