BIODIVERSITY OF GRASSLANDS OF STOŁOWE MOUNTAINS NATIONAL PARK
Journal Title: Acta Scientiarum Polonorum – Agricultura - Year 2016, Vol 15, Issue 1
Abstract
Biodiversity of grasslands depend on several factors, like abiotic conditions, management history of vegetation and landscape structure. Region of Stołowe Mountains National Park is mainly forested, the grasslands cover only 8% of the area, that is about 500 ha. Meadows are distributed in four distinctive complexes: Darnków, Pasterka east, Pasterka west, and Łężyce. The grasslands form discrete patches in forest landscape. In spite of relatively high species richness, only a few grass species (mainly Agrostis capillaris and Festuca rubra) dominated in the vegetation of grasslands. The species richness was influenced mainly by beta diversity (both among releve and complexes), whereas Snannon-Wiener index by alpha diversity. Basic factors influencing beta diversity seems to be soil pH and affinity of particular releve to grassland complex. Differences between old and young grasslands in species richness and Shannon-Wiener index were statistically not significant. On the area of grasslands of Stołowe Mountains National Park numerous protected and rare plant species occurred, e.g.: Traunsteinera globosa, Colchicum autumnale, Platanthera bifolia, Listera ovata, Gladiolus imbricatus, Carlina acaulis, Trollius europaeus, Lilium bulbiferum.
