Land physically covered by grass, independent from its usage.

The tag does not describe the human use to which the area is put, nor if it is managed or not, as long as the area is covered by plants considered to be grasses.

This tag is controversial. The tag landuse=grass is a much more common tag used in a similar way: As of mid-2019, landuse=grass is used over 100 times more frequently than landcover=grass which is also held to be controversial by some. In early 2021 landuse=grass was used over 139 times more often than landcover=grass[1].

Other primary tags used to describe areas with grass growing on them with partly more specific meaning are natural=grassland for grasslands, and landuse=meadow for pastures and meadows.

As an add-on (subsidiary property) tag for other features (e.g. a road indicating a grass surface) use surface=grass.

Other areas of low vegetation, but woody rather than herbaceous, are described with natural=heath and natural=scrub.

Possible tagging errors

  • artificial turf. This should be a separate tag as it has different characteristics compared to vegetation.

Support in editors and data consumers

Support for landcover=grass was declined in OSM Carto[2], JOSM[3] and iD[4].
