Yeah, there's a lot of interesting administrative quirks like that throughout the database. And there are kind of interesting details about exactly which types of trees are catalogued. Generally the data I've been finding and incorporating is where every tree has been individually planted, managed, catalogued.

There also occasionally exist data about natural bushland that has also been audited, but sometimes also bushland that has been sort of described in aggregate.

And then there are datasets of significant trees only (as opposed to every tree within a given park/roadside...).

I wish there were datasets of trees on private land too - they'd be much more useful for ecology etc.
