Scope: Collecting phytosociological relevés (both published and unpublished) from Hungary and the surrounding areas.
Abstract: Hungary has a long tradition to apply, adapt and improve the methods of the Central-European phytosociology. In the 1950’s a national programme was launched to survey and describe the vegetation of the Hungarian landscape by Bálint Zólyomi, Rezs&#337; Soó and their followers. After some prosperous decades, this programme fallen back, but a new generation of vegetation ecologists started to revitalize this fieldwork based, data intensive and plant co-existence oriented science. A special collection of papers and manuscripts was set up in the Institute of Ecology and Botany, Hungarian Academy of Sciences. Main scope of this collection focuses to phytosociology and datasets (relevé) of the vegetation of the Pannonian Region, called CoenoDat Archive. The CoenoDat database was built upon this collection and extended by new relevés.
