|Tools for this tag|
Used for tagging natural, landuse and landcover features where it is possible to identify a single plant or plant taxon which represents the bulk of the biomass of the feature. Often this is easier than trying to assign a physiological classification, which often requires specialist knowledge and detailed survey. It is therefore an early step towards adding tags such as plant_community=* and habitat=*, which have both proved difficult to survey reliably.
This key uses the same semantics as taxon=*. In principle there is no reason why similar keys dominant_species and dominant_genus could be used in the same way. As for taxon, the idea is that a single generic key value can handle a range of levels of detail: for instance Dipterocarp forests in SE Asia can be tagged dominant_taxon=Dipterocarpaceae, pine woodland dominant_taxon=Pinus and typical Gorse scrub can be tagged dominant_taxon=Ulex europeaus/
