In order to preserve habitats and habitat types, the Nature Protection Act in particular prescribes the method of conservation of individual ecosystems such as forest and karst ecosystems and gives guidelines for conservation of wetland habitats, sea, grasslands and agricultural land.

Kinds of habitat types (list of habitat types in the Republic of Croatia based on the National Habitat Classification – NHC), the form, contents and method of use of habitats map, threatened and rare habitat types that need to be conserved in a favourable conservation status and measures for conservation of threatened and rare habitat types in a favourable status are prescribed in the Ordinance on kinds of habitat types, habitats map, threatened and rare habitat types and on measures for conservation of habitat types (OG 7/06) and the Ordinance on Amendments to the Ordinance on kinds of habitat types, habitats map, threatened and rare habitat types and on measures for conservation of habitat types (OG 119/09).

The favourable status of threatened and rare habitat types is ensured by establishing ecologically important areas as parts of the National Ecological Network and the European Ecological Network Natura 2000, by establishing protected areas within the meaning of the Nature Protection Act, incorporation of nature protection requirements and measures into natural resource management plans and physical planning documents as well as by implementing procedures for assessment of acceptability of plans, programmes and projects with conservation objectives of the ecological network and Natura 2000 network.

Habitat types are documented in a habitats map. The habitats map is a GIS database concerning the distribution of individual habitat types in the territory of the Republic of Croatia. The habitats map is kept in the State Institute for Nature Protection and may be viewed on the Institute’s web page.

The presence of threatened and rare habitat types and their conservation status is determined in the process of drafting physical planning documents and natural resource management plans and measures for their conservation are included in these documents. An integral part of these documents is also a cartographic presentation of habitat types (habitats map). At the client’s written request, the Institute shall issue a certified cartographic presentation of habitat types for the requested site along with an explanation in line with the information catalogue of the Institute. Likewise, at the written request of the authority in charge of plan development, the Institute shall issue, for the purpose of preparing physical planning documents, a habitats map in ESRI.shp format

for the requested site.
