that information is a bit specific, as you mentioned - but if you would 
properly document how you are doing it, i think it would be an 
interesting proof of concept project, and there would be no significant 
harm with placing that data in osm.
in the worst case (hopefully never happening :) ), if the data is 
abandoned, it should be easy to remove those tags for one city as being 
outdated and becoming useless.

http://wiki.openstreetmap.org/wiki/Tag:natural%3Dtree suggests tags like 
'genus' and 'species' - those seem to cover your need well :)
