The site is threatened by drainage in the eastern part of Vistonis, and water pollution from intensive agricultural, industrial and domestic sources. The wetland is also threatened by agricultural and urban expansion, excessive water abstraction and hunting. A land-use zonation system exists but has yet to be established legally. Part of the area is a candidate SAC.
