Site description The site is one of the Europe's largest natural bog, transition and fen mire complexes. It is located on the grounds of an active aviation military training area.

Key Biodiversity A total of 151 species have been recorded in the IBA, with 25 National Red Data Book species. Olmany wood and mire complex supports a considerable part (10-20%) of the national populations of Great Grey Owl Strix nebulosa. One of the most valuable huntable birds breeds, Capercaillie Tetrao urogallus, the Polesian population of which is much threatened.

Non-bird biodiversity: 26 mammal species occur on the site, including three National Red Data Book species. European Mink Mustela lutreola, a species threatened in Europe, was recorded here regularly until recently. The Stviga and Lva floodplains support one of the largest populations of Otter Lutra lutra. 687 plant species are found on the site, including 12 National Red Data Book species.
