Human impact on sandy beach vegetation along the southeastern Adriatic coast

We compared the zonation of vegetation and connectivity of coastal plant communities between two distinct areas, one in Montenegro and another in Albania, that differ in terms of human impact, mainly through tourism activities. Transect plots were used to gather data about plant cover and communities, their zonation and connectivity. For description of communities multivariate methods were used and for distribution zonation we used gamma connectivity and richness of boundaries. We found that the transects of vegetation zonation from Albania, with better preserved sites, were richer in the number of boundaries, with more varied combinations of boundaries and the pattern of zonation was also more diverse. On the other hand, there were two plant communities found only in Montenegro. The more impacted transects on the disturbed beaches from Montenegro were also more unidirectional from sea to hinterland but with less ideal zonation. Plant communities from Albania were distributed more straightforwardly but contacts between them were in both directions. The less disturbed beach had zonation very similar to potential vegetation, while plant communities of the touristic beach were fragmented or even substituted by replacement communities. Coastal dune systems in Albania are still well preserved, therefore monitoring and protection measures are recommended
