    Ocena możliwości włączenia Lasów Sobiborskich do sieci obszarów Important Birds Areas oraz obszarów specjalnej ochrony ptaków
    Possibility of inclusion of the Sobibór Forests into Importand Birds Areas and Special Protection Areas networks

    Abstract: One of the greatest challenges of nature conservation is to identify and locate networks of pro tected areas, which will preserve the biodiversity. The paper aims to show the ornithological value of the Sobibór Forests (E Poland) and to emphasize the fact that the network of Important Bird Areas (IBA) and Special Protection Areas within Natura 2000 (SPA) may require additions. The study was conducted in the period of 2008−2016, mainly on forested areas occupying 256 km². The Sobibór Forests are characterized by a large diversity of habitats, but are mainly covered by Scots pine Pinus sylvestris. High diversity of wetlands and marshlands make the Sobibór Forest unique within the country. Three methodologies were used to estimate population size of chosen species: sampling, census and random observations. 31 species from Annex I of the Birds Directive plus 25 species of SPEC or non−SPECE category were observed which allows to consider this area as one of the most valuable for avifauna in Poland. Six breeding species classify the Sobibór Forests as the IBA and SPA. These species include Black Stork Ciconia nigra (8−13 breeding pairs), Common Crane Grus grus (80−120 breeding pairs), Grey Great Owl Strix nebulosa (0−7 breeding pairs i.e. 50−100% of Polish breeding population), Eagle Owl Bubo bubo (6 breeding pairs), White−backed Woodpecker Dendrocopos leucotos (40−70 breeding pairs) and Grey−headed Woodpecker Picus canus (20−40 breeding pairs). Six other species show potential for qualification, but not enough data has been collected yet. The list of this specie includes: Short−toed Snake Eagle Circaetus gallicus, Common Snipe Gallinago gallinago, Stock Dove Columba oenas, European Nightjar Caprimulgus europaeus, Collared Flycatcher Ficedula albicollis and Bluethroat Luscinia svecica. The Sobibór Forests occupy a small area compared to other IBA forests. However, the number of breeding species classifies the surveyed area as 7th among other IBAs. Moreover all eligible species may be considered as a bioindicators of the natural state of the forest. This is proof of the high natural value of this area.
