OpenStreetMap
... a year ago I would have never guessed OSM would turn me into a botanist: osm.org/browse/changeset/8234306
This particular area was overwhelmingly comprised of the homogeneous genus and species of plant. Not sure how to area areas which have a mix of plant types.

maybe somehing like
genus:50% = ganzania
genus:30% = ...
I know this is done by biologists (not the tagging, but the usage of percentage): they throw a square meter in the area and then count what part of the surface is taken by what kind of plants.

Hi aharvey,
I'm interested to record taxonomic and habitat infomation too. I would suggest looking at this page osm.wiki/Key:taxon
I would record taxon:35%=Ganzania rigens . Useful to remember that percentage cover can add up to over 100% because there are multiple layers/canopies within a habitat. Another method which is common, DAFOR (Dominant, Abundant, Frequent, Occasional, Rare) which is often quicker to record and less need for a meter square or measuring an area. taxon:D=Ganzia rigens
I've been working on a wiki for recording habitats (bare bones at the moment) osm.wiki/Habitat

Testing this further for an area e.g. wood, you could try tagging cover:Ganzania=10%
otherwise, using taxon or genus:30%= won't work if there are two species with 30% coverage. The value has to be unique. I have updated the taxon page to reflect this.
