Occurrence data versus range map

I think it would be appropriate to supply an alternative map (perhaps a range map) before rolling back an occurrence data map which, after all, is based on authoritative sources, Australasian Virtual Herbarium, a map which would be improved with the deletion of the specimens collected in NSW.

The map supplied was that shown at the right

occurrence data from AVH

I didn't even notice how wrong it was. Get a broad consensus for whatever you want to call this click-click contribution, maybe at the plant project or reliable sources noticeboard. I do note you have further modified your assertions, why I don't know, but if I convinced you the source was flawed for obvious reasons that was at too great a cost to my time and patience to try any more, "… an alternative map (perhaps a range map)"? For the section of the taxobox with the parameter: range_map = ??? Sorry, something snapped in my head, what is the question? cygnis insignis 00:41, 7 January 2019 (UTC)

The data are from a respected source. I believe it is appropriate for you to leave the map which is properly sourced until its replacement with a range map, even if that range map (as in Macrozamia riedlei) were to ignore half the data without giving an adequate reason for the exclusion of those points, something which is utterly contrary to good scientific practice.

Every "range map" is drawn from occurrence data. Thus, occurrence data maps supplied (including the one here) are useful approximations to any range map that will be made (from occurrence data whether it is just PERTH data or includes specimens collected in WA but held by other equally reputable herbaria) and therefore should stay until replacement. Note that are many species which occur in WA and in other states, e.g., Ficus coronulata. In its case, the AVH occurrence data map seems an excellent approximation to a range map, with no points appearing as obvious outliers. MargaretRDonald (talk) 04:20, 7 January 2019 (UTC)
