In situ and ex situ conservation of endangered species in Poland Puchalski J.T., Burska A., Rybczynski J.J. 1 Both in Poland and all over the world the number of endangered species, of which some have already become extinct is increasing. In Poland, the greatest threat of extinction faces the flora of water habitats, peatbogs and marshes. Also meadow species, particularly those growing in damp and wet soils are endangred (Michalik, 1988). Highly alarming is the extinction of species in the whole areas of their occurrence, which is a common phenomenon especially in the case of endemic species restricted to limited or dispersed areas or represented by small and rare populations. The survival of many biotops of great natural value and the restitution of endangered and threatend with extinction species have been undoubtedly the result of conservation efforts. Nature conservation is realized through the protection of species and biotops in national parks, biosphere reserves, nature reserves, scenic parks and in the areas of protected landscape. Species conservation, based on the pertinent law regulations, allows the continuity of species to be preserved. The protection covers, among others, rare and/or endemic species, species whose range of distribution have borderlines in Poland, and those threatened with extinction due to the degradation of their habitats. 212 plant species, including 5 tree species. 20 species of bushes, shrubs and creepers, 15 ferns, 151 species of herbaceus plnts and 21 fungi, are under the full protection of law in Poland. Partial legal protection covers 28 medicinal and industrial plant species (Regulation of Minister of Forestry and Wood Industry of 30 April, 1993). Plant species which occur rarely and require specific habitat conditions and frequently, are known to botanists only, have been placed on the list of endangered species. Only some threatened species are protected by law; not all protected plants are endangered by extinction. "The red list of Polish endangered vascular plants" (Zarzycki et al., 1992) contains 418 species, which makes about 19 per cent of Polish flora. Among them are 40 already extinct species, the occurrence of which has not been observed on their known sites. Another 40 species are threatened by extinction and 412 species vulnerable, if the factors causing extinction are not eliminated. Besides, 146 rare species which have limited geographical range or are widely dispersed in vast areas can became extinct if their habitats are futher destroyed. There are 36 plant species whose numbers of sites or populations have been decerasing which form a separate category, where the imminence of danger is yet to be determined. There is a growing number of algae (256), slime (88), macrofungi (1013), lichens (602), liverworts (50) and mosses (136), sensitive to changes in the environment. If one considers the 1 Authors' address: Botanical Garden of the Polish Academy of Sciences Prawdziwka 2 02-973 Warsaw Poland

enormous variety of forms, the evolutionary diversification of the above mentioned plant groups, and fragmentary and in complete knowledge of those plants in some areas, one ran presume that some of these species either have not survived or will became extinct before they are identified and classified (Zarzycki et al., 1992). National parks and nature reserves, particularly biosphere reserves, are the best means of ensuring genetic diversity and preserving ecological processes and systems which are the basis of life. In Poland, national parks are created in sufficiently large areas meet the criteria defined by General Assembly of the International Union of Nature Preservation (New Delhi, 1969 and Banff, 1972), on the basis of Council of Ministers regulations. To date, there have been founded 19 national parks of 243.679 ha, which makes 0.78% of Poland's total area. The smallest is the Ojcow National Park of 1.595 ha and the largest is Biebrza National Park of 59.223 ha. The Polish national parks represent main geographical regions. However, most of them are situated in the southern mountainous part of Poland, characterized by nature and landscape of great value. The statutory tasks of the parks are carried out through full or partial protection. Full protection covers, on the average, 24% of the parks acreage. The percentage differs for individual parks, from 2% in the Wielkopolska NP to 97% in the Bialowieza NP, which makes the latter one of the most precious protected area of our continent (Sokolowski et al., 1993). Outstanding in its primeval forest nature and abundance of flora and fauna, the Bialowieza NP has been defined as part of the World's Natural Heritage within the framework of the Convention on Protection of World Natural and Cultural Heritage (Okolow, 1993). 317 plant communities (including 20 endemic) have been given protection in the national parks. In the parks flora there occur numerous endemic species, among others Erysimum wahlenbergii, Cochlearia tatrae, Poa nobilis, some species of the Alchemilla genus from Tatra Mts, Saxifraga moschata subsp. basaltica, Campanula corcontica (Karkonosze), Alchemilla babiogorensis (The Babia Gora NP), Taraxacum pieninicum, Erysimum pieninicum (The Pieniny NP). Besides in the national parks 180 plant species grow under legal protection, among them 155 species under full protection by law (Denisiuk, 1992). Biosphere reserves, being areas not bounded by regional and state boundaries, have special position in the conservation of the natural environment. Their aim is to preserve the variety of plants and animals in theirs natural ecosystems, to protect genetic diversity of species, and to provide the field for ecological and environmental research, of which the results will have crucial importance as points of reference in the case long-term changes of the whole biosphere. Because of their international significance, biosphere reserves are approved by UNESCO. Among the seven reserves in existence in Poland only Lake Luknajno is not a national park. The biosphere reserves covering The Babia Gora NP, the Bialowieza NP, The Slovian NP and Lake Luknajno have been created in order to protect unique, endangered natural heritage. Each of them is an example of incomparable specific ecosystem or landscape. In 1992 a resolution of the Bureau of International Coordinative Council of the Man and Biosphere Project called into being three bilateral biosphere reserves in the area between the Polish and Ukrainian, and the Slovak and Czech borders - the East Carpathians (which is soon to become the first three-state International Biosphere Reserve), the Tatry and the Karkonosze, On the Polish side, the first reserve includes the Bieszczady NP and two scenic parks: the Cisna-Wetlina SP and the San River Valley SP. The second reserve includes the Tatry NP, and the third reserve - the Karkonosze NP. The plans include to enlagre the biosphere reserve network by the Biebrza River Valley, the Wigry NPN,
