Naturbase is a database from the Norwegian Environment Agency (Miljødirektoratet) containing information about protection areas (national park, nature reserves and others), habitats and recreation areas.

Permission to use data

Permission to use the data is clear from the license, as well as verified in e-mail with case number 09/9980–1. The e-mail is in Norwegian and archived in the Norwegian mailing list [1].

The Naturbase dataset Naturvernområder is released under Norsk lisens for offentlige data (NLOD) v1.0: [2]; [3]

For the Naturbase dataset Naturvernområder, Miljødirektoratet requests the following attribution: Kilde: Direktoratet for naturforvaltning. For the other datasets, Miljødirektoratet requests the following attribution: Kilde: Miljødirektoratet.

Downloading data

Prepared OSM files

A tagged OSM file with the full dataset retrieved 2018-03-11 may be downloaded here: Google Disk folder (69 MB)

No simplification has been done. Please use one standard simplification factor 0.2 if needed, so that adjacent areas will fit. Original attributes in capital letters should be removed before uploading to OSM.

Downloading from the Naturbase WMS client

Data are available for download from the Naturbase WMS client. The download icon is in the toolbar to the right, and one of the Naturbase layers must be selected for download to work. All data are available in Shape format, using UTM projections. For best result, use the appropiate UTM zone for the region you are downloading.

You must fill in your name to download data, as well as the purpose of the download. Please state that you are downloading for use in OpenStreetMap when downloading datasets.

Downloading from the map catalogue

Data are also available for download from the map catalogue (without using the WMS client): [4]


All data are also available as WMS services from the official Naturbase site. WMS link is given as "Server URL" and a WMS client is available from the links marked "Innsynsløsninger".

The WMS for the protected areas is predefined in JOSM. Please look for "Miljødirektoratet Protected areas" in the Imagery menu. This is a quick way of checking whether a protected area is missing from OSM.


Dataset Description Import status
Foreslåtte naturvernområder Proposed protection
Helhetlige kulturlandskap Valuable cultural landscapes

Statlig sikra friluftslivsområder

For the Naturbase dataset Naturvernområder, changsets should be tagged with attribution=Direktoratet for naturforvaltning as well as source=Naturbase.

For other datasets from Naturbase, changesets should be tagged with attribution=Miljødirektoratet as well as source=Naturbase.

Naturbase properties

Naturbase properties should have a naturbase: prefix.

Naturbase IDs are called iid, and should be stored as naturbase:iid=*.

Protected areas

See naturvern and kulturminner for tagging scheme. The table below describes how Naturbase attributes have been transformed into OSM tags in the prepared OSM files.

Naturbase attribute OSM tagging Comment
iucn=1,2,5 leisure=nature_reserve


Nature reserves and other areas where animals or birds are protected (will render on Carto).
iucn=3 boundary=national_park National parks.
iucn=4,6,7,8 boundary=protected_area Other protected areas (will not render on Carto).
iucn protect_class iucn=1 -> protect_class=1; else protect_class=iucn - 1
offisieltNavn name Official name given på the law, e.g. "Jotunheimen nasjonalpark".
navn short_name Geographical name of the area, e.g. "Jotunheimen"
vernedato start_date Date of protection established.
forvaltningsmyndighet operator The agency or organization with delegated authority to manage the protected area, e.g. "Nasjonalparkstyret for Jotunheimen og Utladalen"
lokalId naturbase:iid Identification of the protected area, related to the passed law, e.g. "VV00001869".

Multiple areas may have the same iid if they belong to one group of protected areas which were given the protection by the same law passed.

verneform naturbase:verneform Naturbase code denoting type of protection, e.g. "LVOD" for landscape protection area with animal protection. Useful for verifying protect_class, for deciding naming convention and for making changes if OSM tagging is altered in the future.
faktaark url Link to fact sheet for each naturbase:iid, e.g.
verneforskrift related_law Link to lovdata for specific law for each protected area, e.g.

Protected areas with one naturbase:iid may be a collection of multiple individual areas. They are put in a relation with type=boundary and appropriate outer and inner tags. The tags in the above table are held by the relation, with boundary=protected_area as the only tag on the member areas. An area may be both the enclave and exclave of different relations. Please note that a relation needs to be added to the national parks for them to render on Carto (because boundary only renders when tagged as a relation).

If the individual areas which constitute one naturbase:iid have different protection classes then they need to be mapped as separate areas with separate tagging instead of belonging to one common relation. The name of the area may need to be altered to reflect the different protection classes, e.g. one area named "NN naturreservat" and the other area "NN dyrelivsfredning" instead of "NN naturreservat med dyrelivsfredning" on both areas. Most cases have already been handled in the prepared OSM files. If in doubt, the related law defines each area including name.

Access restrictions are defined in the law or by the protection document. Many nature reserves have restrictions for biking, so bicycle=dismount may be appropriate. Bird sanctuaries typically have access restrictions between 15 April and 15 July, which may be tagged as access:conditional=no @ (Apr 15 - Jul 15).

Some large protected areas have buffer or grading zones, e.g. "Steinsbuskaret trekksone" or "Hisdal kalvingssone". These zones are not available from Naturbase. Please do not remove the boundaries of a protected area if it has been superseded by a new and larger area, as the old boundaries tend to be transformed into zones within the new larger area with more granular regulation.
