@ame @openstreetmap It’s quite hard to keep up with trees which may last longer than many buildings (went looking for one yesterday which has gone), but planting gets rearranged all the time in botanical gardens, especially those still used for teaching and research. Somewhere like Tartu would be an absolute nightmare both to map and maintain without that factor.
@ame @openstreetmap Everyone does. As a mapper it’s important to work out what is feasible to keep up-to-date. By all means micromap all the detail for a small area to try it out : you soon learn what works personally.
#iNaturalist does provide for mapping cultivated plants, but those records don’t get the same attention for verification as others. That is the approach I’ve used.
