Site description The site is the remnant of the drained W¹¿ lake, now a fen covered by a system of drainage channels and surrounded by marshy forest of birch Betula and alder Alnus, willow Salix scrub and non-intensively used meadows. The site is drained by the Wê¿ówka river, which flows into Buwe³no lake. The Nietlickie marshes are the largest and most intact fens in the whole of the Mazury lakeland, and are covered by sedge-beds, reedbeds Phragmites and Salix scrub. In 1993 hay harvesting and hunting were stopped there. Because of the large roost of Grus grus this area is intensively visited by birdwatchers. Minor land-uses include chalk mining.
