“…In many European countries, this type of vegetation is receiving much attention in regard to conservation management (e.g. Zobel et al 1996;Dzwonko and Loster 1998;Poschlod et al 1998; Barbaro et al 2001;Jäger and Mahn 2001;Münzbergová 2001;Willems 2001;Wallis De Vries et al 2002;Bąba 2003Bąba , 2004Richter et al 2003;Baier and Tischew 2004;Bornkamm 2006).…”

After abandonment, dry grassland (Festuco-Brometea) areas decline due to gradual overgrowing by woody species and the expansion of perennial tall grass species. Dry grassland vegetation was formed by extensive livestock grazing, thus grazing is considered one of the most natural methods for managing this type of vegetation. Six years after introducing low-intensity sheep and goat grazing in seven nature reserves in Prague (Czech Republic), the following impact of this management on dry grassland vegetation was observed: The cover of expansive woody species, particularly Ligustrum vulgare, and to a smaller extent Cornus sanguinea and Prunus spinosa declined. In addition, a significant, long-term declining trend of the expansive species Arrhenatherum elatius was also observed. Also the cover of Pimpinella saxifraga and Allium senescens declined significantly with regard to statistical evaluation. On the contrary, the cover of Achillea millefolium, Centaurea stoebe, Securigera varia, Elytrigia repens, Erysimum crepidifolium, Falcaria vulgaris, Fallopia convolvulus and Verbascum lychnitis increased. The cover of species characteristic of dry grasslands (Festuco-Brometea) increased significantly. No changes were observed in the number and cover of the Red List species. In addition, the presence of nitrophilous and ruderal species increased. Species diversity also significantly increased. From our findings we can conclude that managing dry grasslands with lowintensity grazing can help to keep dry grassland vegetation in good condition and conserve its plant diversity. Nomenclature: Kubát et al. (2002) for taxa and Moravec et al. (1995) for syntaxa.

“…It seems therefore necessary that active protection measures should be supplemented by the introduction of controlled grazing of farm animals such as sheep and goats. Extensive grazing has a positive impact on the soil structure, restrains the expansion of shrubs and brings about the disappearance of grasses which might be easily replaced by dicotyledonous plants associated with xerothermic grasslands (6,15).…”

SUMMARyThe paper contains the results of monitoring of xerothermic grassland management conducted in the research areas Górkowa Skała and Grodzisko in the Ojców National Park. In Górkowa Skała active protection was implemented for the first time in 2005. In Grodzisko, in turn, the first protection measures were taken as early as 1982, but their systematic implementation was started only in 2000. Already at the current stage of investigation positive effects produced by these measures can be observed, especially in areas with relatively shallow soil profiles (around 30 cm). Plot monitoring results showed, among other things, an increase in the abundance and frequency of occurrence of grassland species preferring full-light conditions with periodic shading that grow in poor and dry soils. However, the obtained results also confirmed the assumption that the implementation of grass mowing, shrub clearance and plant biomass removal alone is not sufficient to ensure the restoration of a typical grassland species composition in deeper soil profile areas.Thus, it seems necessary that these protection measures should be supplemented by controlled grazing of farm animals. STRESzCzENIEPraca zawiera wyniki monitoringu zabiegów czynnej ochrony muraw ciepłolubnych, prowadzonego na powierzchniach badawczych "Górkowa Skała" oraz "Grodzisko" w Ojcowskim Parku Narodowym. Na "Górkowej Skale" ochronę czynną przeprowadzono po raz pierwszy w 2005 r. z kolei na "Grodzisku" pierwsze zabiegi ochronne zastosowano już w 1982 r., ale systematyczne dopiero od 2000 r. zwłaszcza na powierzeniach o stosunkowo płytkim profilu glebowym (ok. 40 30 cm) zabiegi te już na obecnym etapie obserwacji przyniosły pozytywny efekt. Na monitorowanych poletkach stwierdzono m.in. wzrost liczebności i frekwencji gatunków murawowych, preferujących warunki pełnego oświetlenia, z okresowym ocienieniem, porastających gleby ubogie i suche. Uzyskane wyniki potwierdzają również przypuszczenia, że samo koszenie, odkrzewianie i usuwanie biomasy roślinnej nie jest wystarczające do odtworzenia typowego składu gatunkowego muraw na glebie o głębszym profilu. Konieczne wydaje się uzupełnienie zabiegów ochronnych o kontrolowany wypas zwierząt gospodarskich.

“…It is commonly known that majority of xerothermic calcareous grasslands in Central Europe are maintained by mowing and grazing, and when left alone they will convert into shrub, pioneer forest and then into successional forest commu-nities (2,4,5). The consequence of the changes is not only the total rebuilding of species structure of a community but also strong depletion of species richness.…”

SUMMARYThe aim of the study was to show the changes of species number and their frequency in different patches of xerothermic grasslands in the period of 2-3 years, as well as relation between the number and frequency of species which were classified in four ecological groups. We wanted to investigate changes in the frequency of several most threatened species: Cephalanthera damasonium, Adonis vernalis, Lathyrus pannonicus, Linum hirsutum, Sesleria uliginosa and Orchis purpurea. The observations were carried out on 120 m 2 permanent plots situated in the clearing forest reserve "Polana Polichno" in the Ponidzie region. Plots were chosen within the ecotone zone and in the central part of the reserve which represented different management regimes. It was found that within the same patches the mean number of species per 1m 2 did not differ significantly in the period of 2-3 years. The study showed a distinctly higher density of species in patches of grassland situated in the central part of the clearing in comparison with the ecotone patches, especially in the patch where trees and bushes had been cut down a few years earlier. Moreover, an increase in the number of grassland species and decrease in the number of forest herbs species was noted in the ecotone patch which had been permanently cut. nych przez autorów grupach ekologicznych. Obserwacje prowadzono na 120 m 2 stałych powierzchni badawczych usytuowanych w rezerwacie Polana Polichno, położonego w obrębie Ponidzia. Powierzchnie badawcze założono w strefie ekotonu, jak również w centralnej części rezerwatu w miejscach o zróżnicowanej historii użytkowania. Stwierdzono, że w obrębie tych samych płatów średnia liczba gatunków na 1m 2 nie zmieniła się istotnie. Obserwacje wykazały natomiast znacząco wyższe zagęszczenie gatunków w płatach w centralnej części polany w porównaniu z płatami ekotonowymi, szczególnie z płatem, gdzie kilka lat wcześniej wycięto drzewa i krzewy. Stwierdzono również znaczący wzrost udziału gatunków kserotermicznych i spadek liczby gatunków zielnych leśnych w płacie ekotonowym, gdzie prowadzono stałe koszenie.
