This varied moraine landscape is drained by the Omulew and £yna rivers (both rise here). There are many hollows or basins, covering 30% of the site and occupied by lakes, cave-lakes or mires. Thus there are 60 lakes, most of them rather small, with the largest being £añskie (1,070 ha), Kono (552 ha) and Omulew (549 ha). The water-bodies are moderate to rich in nutrients, with only a few of the nutrient-poor type. Aquatic vegetation is species-rich and diverse. Lakes are surrounded by reed Phragmites, etc., beyond which are periodically flooded sedge-beds. In the wide valley there are fens and transitional mires; raised bogs are scarcer. Forests are mainly coniferous, dominated by pine Pinus, and extend onto mires. Broadleaved forest is not common, dominated by hornbeam Carpinus on dry ground and by alder Alnus trees and willow Salix scrub along riversides.
About 160 species have been recorded breeding, with particularly high numbers of a variety of raptors. The site is also important for ducks, Grus grus, and waders during autumn migration, and is a moulting place for 500-600 Cygnus olor.
Pressure/threats to key biodiversity
Threats include nutrient pollution and subsequent plant encroachment in water-bodies, drainage, poaching and excessive hunting, grass burning in spring, intensive transportation, disturbance of nesting birds, impact of fishery on birds, unsustainably intense forest management (tree-cutting, removal of old trees), and over-collection of wild foodstuffs (`Other'). The site comprises the planned Napiwodzko-Ramucka Forest Landscape Park and its surroundings.
