ABSTRACT Oil from the Sea Empress spill in February 1996 contaminated more than 120 miles of South Wales coastline, including rocky shores, sand and shingle shores, mudflats, and salt marsh. Some aerosol sprays also contaminated some maritime cliff along wave-exposed coasts. Some areas of shore, including areas with a high nature conservation value, were heavily oiled. Although much of the affected shore lies on the open coast and is exposed to wave action, large amounts of oil remained on the shores for many months, becoming buried and bound with sediments, percolating deep into cobble and shingle shores, and pooling behind rock features. Oil persistence has been greatest on sheltered shores, particularly where heavy fuel oil stranded. Cleanup activities on these shores have included the use of dispersants, high-pressure washing, low-pressure deluge, trenching, and berm relocation. Numerous studies of the effects of the oil and the cleanup techniques on the intertidal and coastal communities are being undertaken by biologists from various organizations. This paper presents a summary of the results so far.

In the modern agricultural landscape major threats to plant species diversity are loss and fragmentation of habitats and communities. During the last century natural and semi-natural communities have faced also cessation of tradition management and increased load of nutrients. This paper presents a survey of studies on vegetation dynamics of woodlands in the northern part of the Carpathian foothills and of calcareous grasslands on limestone hills near Kraków. The causes of fargoing changes observed in communities of these types and possible management for their conservation are discussed. The nature conservation value of woods can be assessed by means of ancient woodland plant species indicators.

This paper reviews very briefly the main factors of relevance in determining the optimal distribution of nature conservation areas within a region or country. Whilst much will depend on the existing location of areas of high conservation value, the selection of an appropriate strategy for nature conservation within a region will also depend on the likely effects of isolation between conservation areas—which, in turn, will depend to some extent on the types of plants and animals that are to be conserved.Considering a number of alternative patterns of conservation areas, it is concluded that patterns which combine a minimum of fragmentation with extensive regional coverage are likely to be preferred to more fragmented patterns involving the same total area of land.

The bryophytes of the reserve are represented by 71 species: 3 liverworts and 68 leafy mosses. The greatest variety of mosses is typical for forests. Most mosses are epiphytes, which are associated with the trunks and bases of trees - 21,4%, on the soil - 19,7% and on a limestone rock. In the ecological structure of the bryoflora, the features can be traced, zonally determined by the features of the bryoflora of the southern regions with pronounced aridity features. The predominant life form is loose turf - 44.2%, the second position is occupied by dense turf mosses (31,1%). In relation to the degree of asubstrate moisture mesoxerophytes - 29,6% and mesophytes - 27,9% dominate. In relation to the degree of supply of the substrate with nutrients, oligomesotrophs - 37,7%, and mesotrophs - 32,7% are mostly represented. In relation to illumination helioscyophytes occupy a predominant position - 44,6%, in relation to the temperature factor mesotherms occupy a leading position - 50,8%, mesotrophs - 31,5%, mesoeutrophs - 17,4% and eutrophs - 12% are most prominent. The analysis of the spectrum of ecological-floristic strategies of bryophytes has shown a high proportion of species with strategies of colonists and shuttles. The bryological materials confirm the high scientific significance and nature conservation value of the reserve territory.
