Scope: The database contains several vegetatio types from the Mediterranean Basin, Near East and Crimea. However, vegetation plots of other forest types as well as grasslands are stored.
Abstract: Large thematic databases of vegetation plots are increasingly needed for vegetation studies and biodiversity research. This database (GIVD ID: EU-00-026) in January 2024, encompasses records from 19278 vegetation plots (relevés) from 20 countries of the Mediterranean Basin, Near East and Crimea. All vegetation plots are georeferenced, and coordinates are available with different accuracies. The database is accessible through the EVA, sPLOT or by asking the Custodian. The CircumMed Database is an important resource for conducting various types of broad-scale studies in the fields of vegetation classification, plant invasion ecology, macroecology and biological conservation.
