Zróżnicowanie florystyczne i wartość użytkowa zbiorowisk trawiastych na terenie zabytkowego Ogrodu Sentymentalno – Romantycznego w Arkadii
Journal Title: Łąkarstwo w Polsce - Year 2017, Vol 20, Issue
Abstract
The aim of the study was to analyze the floristic composition of the grass communities in the historic Garden in Arcadia (Nieborów community, Łódź voivodeship) and evaluation of their fodder value.The objects of the research were plant communities in part of the Garden (0.72 ha; geographical coordinates: 52°08′31′′N, 20°01′35′′E) where restoration of extensive sheep grazing is planned. The assessment of the sward state was carried out in the first re-growth in 2017. Sward was occasion- ally mowed (usually once a year or once every two years), without fertilization, but on a part of the object, it has not been mowed for a couple of years and only next to the paths sward was cut several times during the growing season. Natural values (number of species total and in patch, Shannon-Wiener’s floristic diversity index) and production value (yielding, fodder value) were evaluated. There were also determined the thickness of the dead organic matter.The grass surface under study, within the historic Garden in Arkadia is characterized by the presence of 65 species of vascular plants and 7 meadow plant communities. The most constant components of the distinguished phytocenoses are: Festuca rubra, Poa pratensis, Elymus repens, Dactylis glomerata (abundance above 50%). Occurrence of xpansive species, herbaceous species and tree seedlings, currently in a small proportion in the sward, may cause the disappearance of open surfaces in a short time. The state of plant communities is the result of improper use, and points to the need to take action to stop their degradation processes. In order to restore the multi- species pastoral communities in the Arcadian Garden, with many floristic aspects, and to preserve cultural value, introduction of the plant species that testify to the historical identity of this place is recommended.
