The Ecological Main Structure (EHS) is a cohesive structure of areas with a special nature quality. The current state of EHS is on the map. It is updated annually. The implementation of the ecological connection zones (EVZ) and robust connections (RV) are also provided. The search areas EVZ and RV are a separate file in GBI.
