Abstract

This study deals with the floristic and vegetation investigations of Golestanak Protected Area, an ecotone with nearly 1800 ha area located between the timberline and subalpine-alpine zone in the central part of the Alborz Mountain Range (Mazandaran Province). A total of 172 taxa, belonging to 39 families and 126 genera were identified, including 138 dicotyledones (99 genera) and 32 monocotyledones (25 genera). Based on a system of sixty sample plots taken randomly along five transects and using Sørensen’s distance measure (Index BC=Bray and Curtis) and Ward’s group linkage methods in a cluster analysis, nine plant communities were identified.
