The most valuable forest communities are willow-popular carrs Salici-Populetum. Although it is a common part of the landscape of the Bug Valley, it does not occupy large pieces of its area. There are also riverside carrs ( Fraxino-Ulmetum ) which grow only on fertile round of the valley and have a rich gound flora. The waterside of the river, the old river-bed and the midstream islands are covered by osier beds.

It is worth to mention that old river-beds are very characteristic with typical aquatic plants and a variety of animal species. They are covered by rush-plants, especially by several species of sedges. On the other hand places where the land is dry, sandy and uplifted are covered by xerothermic vegetation.

Fauna

There are 290 species of vertebrates: mammals, birds, reptiles, amphibians and fish, that is 52% of our Polish species diversity of vebrates.

Research done in 1987 - 2000 showed that there are 150 species of birds within the boundaries of The Podlaski Przełom Bugu LP, probably breeding. Three spiecies of this group (Stone-curlew Burhinus oedicnemus, Hen Harrier Circus cyaneus, Roller Coracias garrulus) appeared only in 1987. Such a great number of breeding species is due to a high habitat diversity.

Species directly attached to the river-bed of Bug, connected with riparian scarps, beaches and midstream islands are Kingfisher Alcedo atthis, Sand Martin Riparia riparia, Little Ring Plover Charadrius dubius, Ringed Plover Charadrius hiaticula, Common Sandpiper Actitis hypoleucos, Little Tern Sterna albifrons, Common Tern Sterna hirundo and Common Gull Larus canus.

Other group of birds such as : River Warbler Locustella fluviatilis, Penduline Tit Remiz pendulinus, Scarlet Rosefich Carpodacus erythrinus, Hoopoe Upupa epops, Wryneck Jynx torquilla resides at riparian osier beds and willow-popular carrs.

Lowmoors in the valley, meadows and watersides of overgrowing old river-beds make suitable conditions for predation and nesting for Scolopacidae like: Black-tailed Godwit Limosa limosa, Lapwing Vanellus vanellus, Redshank Tringa totanus and Snipe Gallinago gallinago.

Old river-beds and fishing ponds typical for the eastern side of the LP cause the occurrence of : Spotted Crake Porzana porzana, Little Crake Porzana parva, Red-necked Grebe Podiceps grisegena, Mute Swan Cygnus olor, Pochard Aythya ferina, Moorhen Gallinula chloropus, Mallard Anas platyrhynchos, Black Tern Chlidonias niger.

Large forest complexes and mature stands are inhabited by: Eagle Owl Bubo bubo, Lesser Spotted Eagle Aquila pomarina, Black Stork Cigonia nigra, Black Woodpecker Dryocopus martius, Stock Dove Columba oenas, Nutcracker Nucifraga caryocatactes, Red-breasted Flycatcher Ficedula parva, Honey Buzzard Pernis apivorus.

Other groups of vertebrates, worth to emphasise because of their great species diversity within the boundaries of the Podaski Przełom Bugu LP, are reptiles ( 67% of the number of species occurring in Poland ) and amphibians ( 56% ). A number of 41 species of fish were found within the boundaries of the LP that is 37% of Polish list.

There are 33 species of mammals, 35% out of Polish number. Wolf Canis lupus, as a rare species, was seen not long ago. Otters Lutra lutra and Eurasian Beavers Castor fiber occur more often. The most endangered with extinction is European Pond Tortoise, it occurs occasionally in some old river-beds.
