Vegetation types of Robinia pseudoacacia forests in the NW Balkan Peninsula

Robinia pseudoacacia dominated forest communities have been intensively studied in the NW Balkan Peninsula (Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Serbia). It is considered one of the most widespread and invasive alien tree species in temperate regions of the northern hemisphere, considered as both ecologically risky and economically important in many countries. Phytosociological literature data of the Robinia pseudoacacia stands in the area are very sparse with almost no published vegetation plots. Their classification into phytosociological system is based on the information from Central Europe. The aims of this study are to fill the gap in the field data on Robinia pseudoacacia stands in the area of NW Balkan Peninsula and to identify main vegetation types of Robinia pseudoacacia forests in the area. A database of 248 vegetation plots was established and numerically classified by agglomerative hierarchical clustering. 11 vegetation types classified into three alliances were obtained - Chelidonio majoris-Robinion, Balloto nigrae-Robinion and Lauro nobilisRobinion. Their floristic composition, ecological conditions and geographical distribution were elaborated.
