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 relevés and complexes), whereas Snannon-Wiener index by alpha diversity. Basic factors influencing beta diversity seems to be soil pH and affinity of particular relevé 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.

Bioróżnorodność łąk zależy od szeregu czynników, jak: warunki abiotyczne, historia użytkowania roślinności i struktura krajobrazu. Obszar Parku Narodowego Gór Stołowych porastają głównie lasy; zbiorowiska trawiaste zajmują zaledwie 8% powierzchni, czyli około 500 ha. Obszary łąkowe są rozmieszczone w czterech odrębnych kompleksach: Darnków, Pasterka wschodnia, Pasterka zachodnia i Łężyce. Łąki tworzą odrębne płaty na tle krajobrazu zdominowanego przez lasy. Pomimo stosunkowo wysokiej różnorodności biologicznej roślinność łąk jest zdominowana przez zaledwie kilka gatunków traw (głównie Agrostis capillaris i Festuca rubra). Różnorodność gatunkowa jest kształtowana głównie przez różnorodność beta (zarówno pomiędzy zdjęciami fitosocjologicznymi, jak i pomiędzy kompleksami), podczas gdy wskaźnik Shannona-Wiennera przez różnorodność alfa. Głównymi czynnikami wpływającymi na różnorodność beta były odczyn podłoża i przynależność poletka badawczego do konkretnego kompleksu łąk. Różnice pomiędzy starymi a nowymi łąkami w odniesieniu do różnorodności biologicznej i wskaźnika Shannona-Wiennera nie były istotne statystycznie. Na obszarze łąk Parku Narodowego Gór Stołowych zostały odnotowane liczne gatunki objęte ochroną prawną i uznane za cenne, np.: Traunsteinera globosa, Colchicum autumnale, Platanthera bifolia, Listera ovata, Gladiolus imbricatus, Carlina acaulis, Trollius europaeus, Lilium bulbiferum.
