Hello dikkeknodel,
nice mapping work on South Georgia - but you should probably be aware that there is no scrub vegetation around there - to my knowledge there are hardly any woody plants growing on South Georgia. What you identify as scrubland on images is probably mostly tussock grass formations.
See
for background info on the vegetation of South Georgia.

Hi imagico
Thank you for the compliment and for the comment.I've selectively read the article and it explicitly mentions the northwestern area near Elsehul as extensively grown with tussock, additionally there should be some grass heath at higher altitudes where the soils is better drained.
From this imagery it is hard if not impossible to judge what is heat and what tussock, so I will tag everything as natural=grassland.
Cheers,

Thanks.
If you can reliably identify differences in the vegetation from available images it does not hurt to differentiate them with supplemental tags (like grassland=*).

Actually, natural=tundra may be better... It is less precise maybe, but since no accurate survey is possible without starting an expedition, it may be more applicable.

natural=tundra does not say anything about the vegetation except for that it is without trees. I would advise against it. Grassland is completely fine here for areas with vegetation.
