Sava RBMP Draft version 6.2 Sava River Basin Management Plan Disclaimer The Sava RBMP is based on data delivered by the Sava countries. Where needed, other data sources have been used. Sources other than the competent authorities have been clearly identified in the Plan. A more detailed level of information is presented in the national RBMPs of Slovenia and Croatia as a European Union Member State and Accession Country, respectively, at the time of preparing this document. The Sava RBMP should therefore be read and inter- preted in conjunction with the national RBMPs. Where inconsistencies may have oc- curred, the national RBMPs are likely to provide the more accurate information. An overall contribution to the Sava RBMP development and data were provided by the experts from institutions listed below: Slovenia: Ministry of Environment and Spatial Planning, Institute for Water of the Re- public of Slovenia, Environmental Agency of Slovenia, Geological Survey of Slovenia, In- stitute for Nature Conservation of the Republic of Slovenia. Croatia: Ministry of Regional Development, Forestry and Water Management, Ministry of Sea, Transport and Infrastructure, Croatian Waters, State Hydrometeorological Service of Croatia, State Institute for Nature Protection, Croatian Geological Survey, University of Zagreb - Faculty of Science, The Institute of Economics, Zagreb.
