Różnorodność florystyczna i walory przyrodnicze eutroficznego śródpolnego oczka wodnego
Journal Title: Łąkarstwo w Polsce - Year 2016, Vol 19, Issue
Abstract
The area of 1.7 ha (N 52°57’06”, E 17°17’80”) described in the article is a field pond – a naturally formed depression with no outlet and with a variable water level. The research was conducted on small transects in 2011 and 2012. The investigations revealed that there were expanses of rush communities of the Magnocaricion and Phragmition syntaxa in a relatively small area. It is possible to see a wide range species both of the Molinio-Arrhenatheretea, Phragmitetea class and the Alnetea glutinosae class. The middle of this shallow body of water is covered with a thick layer of lesser duckweed (Lemna minor) and species of the Potametea class, mainly with a complex of ‘water lilies’ with white water lilies (Nymphaea alba) and yellow water lilies (Nuphar lutea). These are almost only native species. The edge of the pond is covered with bulrushes (Typha latifolia) and common reeds (Phragmites australis). There is a complex of Salicetum pentandro-cinereae scrubs and woodlots with rich nitrophilous groundcover around the pond. Segetal complexes of farmland are the zone situated at the greatest distance from the water.The area in question is also an interesting scenic enclave in the agricultural landscape. It is of high aesthetic value. The landscape is distinct from that of the neighbouring areas. There are valuable and rare components of animate and inanimate nature. The area includes plant species which are partialy protected by law (Regulation of the Minister of the Environment of 16 October 2014), i.e. European white water-lily (Nymphaea alba) and protected habitat (Regulation of the Minister of the Environment of 13 April 2010), i.e. Oxbow lakes and natural eutrophic bodies of water (vegetation complexes with Nymphaeion, Potamion), community code: 3150.The aim of the study was an analysis of the floristic composition and natural values of complexes situated within the field pond and in its near surroundings.
