NATURE PROTECTION IN THE POLISH PART OF THE BIALOWIEZA FOREST

CURRENT STATUS AND NATURAL VALUES

In the Polish part of the Bialowieza Forest (62,500 ha) the most important protected area is the Bialowieza National Park with an area of 10,502 ha (of which 4,747 ha are under strict protection). It is the oldest national park in Poland, started in 1921, and fulfils all the criteria for protected area category II (National Park) status according to the standards of the IUCN. The Bialowieza National Park also has the status of a World Biosphere reserve (since 1977) and a World Heritage Site (since 1979). Around the park, a buffer zone of 3,224 ha contains only forested area belonging to the forest superintendencies of Browsk and Bialowieza. There are also buffer zones located around the borders with the villages of Bialowieza, Pogorzelce and Masiewo, from where there could be potential threats. Since 1992, a strictly protected area of the park, together with a similar sector of the Belarussian State National Park "Belovezhskaya Pushcha" (4,500 ha), has created a Polish-Belarussian cross-border World Heritage Site. In 1997 the BNP, as the first national park in Poland, was distinguished with a European Diploma.

The remaining areas of the Bialowieza Forest form, since 1994, the Promotional Forest Complex "Bialowieza Forest". The task of such complexes is to engage in ecologically-based forestry management. This implies management to preserve the natural biodiversity of ecosystems. There are 20 nature reserves (covering 3,430 ha) of which two are under strict protection (Siemianowka and to an extent Michnowka).

Moreover, there are about 1,200 trees protected as nature monuments. The complete Polish section of the Bialowieza Forest, together with its surroundings, form the Protected Landscape Area (76,041 ha), although this form of nature protection is essentially "statistical" and has hardly any real role in the protection of natural resources. Other forms of nature protection include buffer zones around the nests of Black Storks and birds of prey, as well as delimitated ecologically valuable ground.

Within the Polish part of the Bialowieza Forest, 100 plant communities are occurring. Of these, 40 are known from the BNP including 20 forest communities. The most characteristic forest forms in Bialowieza are deciduous forests and mixed coniferous forests of the subboreal type. The flora of the Bialowieza Forest includes 1040 species of vascular plants, more than 3000 species of fungi (including 500 mushroom species), 375 species of lichens and 200 of mosses. Apart from the European Bison (Bison bonasus), the fauna of the Bialowieza Forest include Red Deer (Cervus elaphus), Roe deer (Capreolus capreolus), Elk (Alces alces), Wild Boar (Sus scrofa) and rarer species such as Beaver (Castor fiber), Wolf (Canis lupus) and Lynx (Felis lynx). More than 175 species of breeding bird species have been recorded, including 14 species of raptors, 8 species of owls and 9 species of woodpeckers. Birds specific to primeval forests and habitats unchanged by man are numerous. These include Black Stork (Ciconia nigra), Crane (Grus grus), Lesser Spotted Eagle (Aquila pomarina), Booted Eagle (Hieraaetus pennatus), White-backed Woodpecker (Dendrocopos leucotos), Three-toed Woodpecker (Picoides tridactylus), Eagle Owl (Bubo bubo), Pygmy Owl (Glaucidium passerinum), Tengmalm's Owl (Aegolius funereus), Hoopoe (Upupa epops), Collared and Red-breasted Flycatcher (Ficedula albicollis and F. parva) and Nutcracker (Nucifraga caryocatactes).

Moreover, 12 species of amphibians and 7 species of reptiles are living here. There are many thousand species of insects including many rare species of beetles, moths and butterflies of which a number have become differentiated into local subspecies adapted to the specific conditions of the Bialowieza Forest.

THREATS

The most serious threats to the nature of the Bialowieza Forest come from the fragmenting of the remaining natural old growth stands in the Promotional Forest Complex "Bialowieza Forest" over an area of 3,600 ha. This threatens hundreds of plants and animal species that are relics of primeval forests. As a result of forest management, even under the regulations in force in the Promotional Forest Complex, these stands are being progressively transformed. Instead of stands with complicated spatial structures, multiple species of varying ages adapted to local conditions, stands are formed with simplified structures offering a reduced diversity of flora and fauna.

Populations of species that are relics of primeval forests loose contact with one another, and eventually they will become extinct. They are replaced by newcomers, often invasive species, which compete with native ones. A clear example of such a species is the American Mink (Mustela vison).

Another threat comes from the disturbance of hydrological conditions as a result of land reclamation and hydro-technical regulatory works carried out in the Bialowieza Forest and in its surroundings. Effects of such activity may become apparent many years after their realisation.

Other threats come from the abandonment of numerous traditional activities, mainly at the expense of extensive farming and cattle breeding methods formerly in use. This process leads to a decrease in landscape diversity through the removal of meadows along the riverbeds and a reduction in the area of settlement clearings. One effect is a decrease in the feeding grounds of large ungulates such as the European Bison. These processes are followed by the eventual extinction of several rare species of plants and animals including the Corncrake (Crex crex), a bird species threatened world-wide, and some invertebrates including certain butterflies. For the same reasons (in this case as a result of the artificial afforestation of the Lesna-Prawa river valley) a tertiary relic-species, the False Ringlet (Coenonympha oedippus), has disappeared.

PROPOSED ACTIVITIES

Independently from any decision to enlarge the Bialowieza National Park to include all the Polish area of the Bialowieza Forest, it is necessary to take several measures for the protection of existing natural values in the Bialowieza Forest.

These measures include:
