Block forest (roso pendulinae-tilietum cordarae), a new forest community of the carpathian basin (Cerová Vrachovina, Slovakia)

A new plant association (Roso pendulinea-Tilietum cordatae), similar to the Poo nemoralis Tilietutm cordatae Firbas et Sigmud 1928 (Central European siliceous block field forest), has been dexcribed. This forest commuity develops on the periglacial block fields of southern Slovakia (cerova Vrchovina, syn.: Nograd-Gomor basalt region). The community has been separated from the Mercuriali-Tilietum Zolyomi et Jakucs 1958 common in the submontane belt of the Pannonicum using phytocoenological comparative analyses.The ecological demand and the species combination cleary distinguish this association from the older forest communities described earlier from northern periglacial block fields of Hungary.
