A hazai Mura-ártér fehérnyár-ligetei [Senecioni sarracenici-Populetum albae Kevey in Borhidi & Kevey 1996

Abstract

White poplar riparian forests along the upper Mura River, Hungary. I studied the phytosociological characteris-tics of white poplar riparian forests (senecioni sarracenici-Populetum albae) growing along the Mura river in south-west Hungary by collecting and analyzing twenty vegetation samples. These forests grow in the highest parts of the lower floodplain on alluvial soil, which developed over gravel and coarse sand. Their species composition and rich shrub layer make them clearly distinct from white willow forests (leucojo aestivi-salicetum albae), which grow1–1.5 m below them on heavy, muddy soil, and have no shrub layer at all. They also differ from hardwood riparian forests (Carici brizoidis-Ulme-tum) growing in the upper floodplain. The herbaceous layer in these forests often host plants that are rare or fully absent from other parts of the Great Plains, such as adoxa moscha-tellina, Carex brizoides, C. remota, C. strigosa, Chrysosp-lenium alternifolium, Corydalis solida, equisetum hyemale, Fritillaria meleagris, Oenanthe banatica, Omphalodes scor-pioides, scilla drunensis, stellaria nemorum. The association is placed in the sub-alliance Populenion nigro-albae Kevey2008.
