FLOWER IVY HEDERA HELIX L. IN THE FORESTS SURROUNDING SZADEK

Summary/Abstract: In 9 sites of Hedera helix occurrence were recorded in the forests surrounding area Szadek. The species grows mainly on the fresh-mixed and – fresh forest site types. 195 flowering and fruiting specimens were found. The most frequent support for Hedera helix offer such tree species as black alder Alnus glutinosa, common oak Quercus robur and Scots pine Pinus sylvestris. Flowering specimens of the climber are found growing at forest edges, in degraded communities of mixed linden-oak- and -riparian forests as well as in the fringes of gaps in forest stands under reconstruction. The dispersal of Hedera helix in forests is attributed to both the rise in annual average temperatures and, in particular, higher average temperatures in winter months, and to the fragmentation of forest.
