Site description (2000 baseline):
Site location and context
The area is part of the great Tuchola `sandr' (outwash plain of glacial origin). The terrain is varied, with elevated plains, extensive hills, many hummocks, valleys and troughs, and is drained by the Brda river and its many tributaries (the largest being the Zbrzyca). Some of the rivers have steep gradients and strong flows. Of 60 lakes in this area, the largest is Charzykowskie lake (1,363 ha), and the deepest is Ostrowite lake (43 m deep). Many are flow-lakes, being part of the Brda river system, and most have low to moderate levels of nutrients. Forests are dominated by pine
Pinus. On richer soils there are dry-ground forests of hornbeam
Carpinus, birch
Betula, beech
Fagus and oak
Quercus, and near watercourses and reservoirs there is riverside carr and forest of alder
Alnus. There are fens, connected with rivers and lakes, as well as (in hollows) raised bogs and transitional mires.
An important wintering site for swans
Cygnus (all three European species), which also holds 10% of the national population of
Pandion haliaetus on passage. A total of 107 species have been recorded breeding; breeding species of global conservation concern that do not meet IBA criteria:
Haliaeetus albicilla (three pairs).
Pressure/threats to key biodiversity
Forestry work close to, or in, buffer zones designated for nesting
Haliaeetus albicilla,
Bubo bubo and
Ciconia nigra disturbs these particular species, as does tourism/recreation.
