Based on the preliminary work of the Interreg project coop MDD (May 2019; client: WWF Austria) the UNESCO documents for the submission of the planned transboundary biosphere reserve were to be completed. E.C.O. coordinated and accompanied representatives from all participating countries (AT-HR-HU-RS-SI) and prepared relevant data and information to finalise the Nomination Form for the submission to UNESCO. A map (shape file) of the biosphere reserve was also prepared to show the exact zoning; one of the essential elements of the submission.
