The north-western part of Solska forest. Wet soils cover half of the area, which is drained by many natural watercourses, channels and ditches. Forest vegetation is dense and species-rich, dominated in places by pine Pinus, fir Abies, spruce Picea, oak Quercus, beech Fagus, ash Fraxinus and alder Alnus. Many stands have a natural character with some old-growth trees. Raised bogs and transitional mires occur in areas with little water flow, and were used in the last century for fish-ponds. There are 150 such former ponds, each with an area of 10-50 ha and a varying amount of plant cover.
Breeding species of global conservation concern that do not meet IBA criteria: Aythya nyroca (2-3 pairs), Crex crex.
Pressure/threats to key biodiversity
There are 15-20 forest-fires per year, resulting from widespread recreational use of the area, although the fire-fighting response is well organized. Widespread tree-death or damage by infestations of insect pests (`Natural events') can also be a problem, although there is a well-organized monitoring system. In 1994 the area became a `forest promotion complex', where management (based on ongoing research) aims to re-create approximately natural forest conditions (including hydrology and soils) while allowing some exploitation of forest resources and products to continue, combined with public awareness activities. The site is an amalgamation of two sites (the former PL073-PL074) identified in the previous pan-European IBA inventory (Grimmett and Jones 1989).
