That is a good start, if you could beef up this table with the 
leaf_type/leaf_cycle and genus tags that would be what i had in mind.  
Both creating this and verifying that this is actually consistent in 
the data can be done with a simple GROUP BY query on the data.

You probably misunderstood me then - i was not questioning the accuracy 
of the data (although with a survey date of 2013 there are probably 
some trees removed for building stuff in the meantime), i was worried 
about mismatches with the existing data in OSM.  It is quite possible 
that resolving those usually needs to modify the existing data rather 
than the trees but you should have a solid plan for handling this kind 
of problem.  Just dumping the data and hoping that mappers will sort 
out problems later is not the way to go.
