Site details


Site description: Pisz forest lies on the border between the Great Mazury lake region and the Mazury lowlands, and the Pisa and Krutynia rivers flow through this area. The largest lake in Poland˜Œniardwy (1,097 km2)˜is located in the north-western part of the site, and there are also a dozen other lakes. Many tree species reach the limit of their range here. There are coniferous forests of pine Pinus with some smaller areas of spruce Picea and broadleaved dry-ground forest of lime Tilia and hornbeam Carpinus. Around the lakes in wet areas there are alder Alnus forests and different kinds of mire.
Rationale for qualifying as KBA: This site qualifies as a Key Biodiversity Area of international significance that was identified using previously established criteria and thresholds for the identification of Important Bird and Biodiversity Areas (IBAs) and for which available data indicate that it does not meet global KBA criteria and thresholds set out in the Global Standard.
Additional biodiversity: Species of global conservation concern that do not meet IBA criteria: Aythya nyroca (rare on passage), Crex crex (frequent breeder).
