Invasive Species Compendium

Detailed coverage of invasive species threatening livelihoods and the environment worldwide

Abstract

Rare and interesting species of vascular plants from limestone outliers in the buffer zone of the Ojców National Park (Kraków Upland).

Abstract

The paper presents a list of 73 vascular plants with descriptions of their localities and habitats. These data resulted from an investigation on the plant cover conducted on limestone outliers and slopes (Duże Skałki, Małesowa Skała, Osypiec, Góra Moroń) in the buffer zone of the Ojców National Park (Kraków Upland). That list includes one species listed on the Polish red book (Verbascum chaixii subsp. austriacum), three species on the red list (Festuca poliens, Gagea pratensis, Melica transsilvanica), eight species under strict law protection (Carlina acaulis, Centaurium erythraea, Epipactis helleborine, Gentianella ciliata [Gentianopsis ciliata], Jovibarba sobolifera [Sempervivum globiferum], Lilium martagon, Melica transsilvanica, Melittis melissophyllum) and six species partly protected (Asarum europaeum, Convallaria majalis, Frangula alnus [Frangula dodonei], Hedera helix, Primula veris, Viburnum opulus). Nine species are rare or endangered in the Ojcow National Park (Gagea pratensis, Inula ensifolia, Inula hirta, Laserpitium latifolium, Melica transsilvanica, Peucedanum cervaria, Pulmonaria mollis, Trifolium rubens, Veronica austriaca). The kenophytes group, meanwhile, includes seventeen species. Limestone outliers are considered biodiversity centres in the buffer zone of the Ojców National Park. It was observed that succession is the main problem because it leads to decrease grasslands area and decline of rare xerothermic species in the Park and its buffer zone as well. Active protection may stop successional changes but successive studies in the buffer zone are necessary.
