The wildlife of Poleski National Park is extremely rich, although it covers only around 10.000 hectares and most of the area is water- peat bog. Diversity of habitats favours existence of numerous species of plants and animals, including species present only in this region of Poland.

Poleski National Park represents the wildlife of Lenczynsko-Wlodawska Plain and includes natural lowland bog, mid and high peat bog, with their own diversity of species. Every year, after winter time, they form picturesque pools which attract migrating water-marshbirds, whereas permanent pools are a feeding and nesting ground to numerous species. Due to a vast diversity of habitats, flora and invertebrate lovers won’t be disappointed. There grow insect-eating plants, orchidsOrchidaceae and many others of postglacial origins. The park is a sanctuary of the moose Alces alces, marsh turtle Emys orbicularis, beaver Castor fiber and otter Lutra lutra.
