This nice cover from Poland depicts a single stamp issued in 2022, celebrating the Nature reserve of
"Bialowieza Puszcza".
Białowieża Forest (or Biełaviežskaja Pušča; Polish: Puszcza Białowieska) is one of the last and largest remaining parts of the immense primeval forest that once stretched across the European Plain. The forest is home to 800 European bison, Europe's heaviest land animal. UNESCO's Man and the Biosphere Programme designated the Polish Biosphere Reserve Białowieża in 1976 and the Belarusian Biosphere Reserve Belovezhskaya Puschcha in 1993. The forest has been designated a UNESCO World Heritage Site and an EU Natura 2000 Special Area of Conservation. The World Heritage Committee by its decision of June 2014 approved the extension of the UNESCO World Heritage site "Belovezhskaya Pushcha/Białowieża Forest, Belarus, Poland", which became "Białowieża Forest, Belarus, Poland".
