The paper presents 15 collections of bones of mammals (15 sites, 357 specimens) from the Geological Museum of the Polish Geological Institute, which were gathered during the firsthalf of the 2(fh century. This is the first study of these collections. The remains of woolly mammoth, woolly rhinoceros, bison, reindeer, horse and predators, and other bones complement the record of their occurrence in central Europe during the last glaciation. The geological position was established for most sites based on both published sources and own research (Kadzielnia and Sitkowka quarries). The collections were obtained from fluvial (woolly mammoth and rhinoceros), aeolian (mammoth remains) and cave sediments (taxonomic diversity of mammals with predominance ofpredators). It has been confirmed that typical Pleistocene sediments of the Kadzielnia quariy occur only in the Jaskinia Jeleniowska Cave and Schronisko nad Przepasciq Cave. The analysis of the literature suggests that the majority of bones representing all collections are ofVistulian (Wiirm) age, mainly the Grudziqdz lnterstadial.

This study aims at determining whether the inverse relation between wood quantity per unit river area and channel width, recognised in streams of small and medium width, typifies also wide mountain rivers. This is done by comparing wood distribution for Finzbach and Kamienica Streams, 14 and 9 m in width on average, and the Czarny Dunajec River with mean width of 52 m. In both streams, the values of total wood storage were unrelated to channel width, whereas the increase in channel width was reflected in a pronounced decline in specific wood storage. In the wide Czarny Dunajec, a marked trend of increasing total wood storage with the increase in river width was observed. The width-related variation in total wood storage in the river was so high that it overcame the influence of increasing channel area on calculated values of specific wood storage, and this parameter also increased with increasing river width. The contrasting patterns of wood storage observed in the watercourses point to different mechanisms governing wood retention in the channels narrower and wider than the height of trees growing on their banks.

Longitudinal changes in the granulometry of bar sediments were investigated in an 18 km long reach of the Czarny Dunajec to determine the impact of human activity in the river on depositional conditions in its channel. In the upper part of the reach, gravel extraction carried out in the past decades has led to deep channel incision and considerable coarsening of the bed material. Coarse, well sorted bar gravels occur also in the narrow, regulated channel sections in the middle part of the reach. Remarkably fine bed material typifies a wide, natural channel section in the lower part of the reach, and this section seems to function as a sediment sink, reducing bed-material delivery to a downstream located dam reservoir.

During a winter-spring season, physicochemical variables and plankton dynamics were studied in Lough Derg (Ireland). Samples were collected monthly from three water layers (surface, middle and bottom) at a deep central sampling point on the lake. As expected, phyto- and zooplankton densities and chlorophyll a concentrations were low during the study period, probably reflecting low temperatures and wind-driven turbulence typical of the winter-spring period. Diatoms and rotifers were the most abundant phyto- and zooplankton groups, respectively.

The transitional bog in upper pARt of Łopień Mt. hARbours rARe in the CARpathians plant communities: Eriophorum angustifolium-Sphagnum fallax, CARici-Agrostietum caninae and Bazzanio-Piceetum. Also rARe peat bog plant species, as: Drosera rotundifolia, Eriophorum vagi-natum, Oxycoccus palustris and Vaccinium uliginosum occur here. Presently this bog is threatened by overgrowing with shrub willows.

The total area of fen vegetation in Kraków city didn't exceed half a hectare. Spring fens were overgrown by: Caricetum davallianae, Sphagno warnstorfii-Eriophoretum latifolii variant with Tomentypnum nitens, Carici canescentis-Agrostietum caninae, Carex nigra and C. panicea community and Menyanthes trifoliata community. Abandonment of meadows has resulted in degradation and overgrowing spring fens scattered among them.

The idea of establishing protected landscape parks was put forward in Poland 50 years ago. The result was fairly quick expansion in the number of protected landscape areas, up to 120 by now. Figures 1 and 2 show the progress in creation of such areas and their geographical distribution. The major goals and approach in management of the landscape parks were changing in time. The following stages may be distinguished in the landscape parks policy: protection of environment followed by landscape protection, protection of nature diversity and currently - biodiversity conservation (in accordance with Natura 2000prerogatives). Also "geodiversity" make it necessary to treat the existing landscape parks as the potential areas of geoparks. One of key requirements which should be met by geoparks is a network of geological sites subjected to legal protection. These sites are the "back-bone" of geopark. The paper presents situation in the Polish landscape parks with regard of this requirement by the end of the year 2008. At that time the number ofgeoconservation objects selected and categorized in 75 of those parks reached 551 (Fig. 3). Table 1 shows the typology of geological sites in relation to their importance for the Earth sciences The objects of the category A are the most valuable for geology whereas the remaining ones are mainly ofgeomorphological (B) and hydrological (C) value. Tables 2, 3 and 4 show the current state of conservation of geological sites in Polish landscape parks. In that presentation the area of Poland was divided into two parts with the line of extent of the Warta Glaciation as the boundary (Fig. 2). The Pleistocene deposits predominate north of that boundary whereas rocks of older stratigraphic units crop out at the surface south of it.
