alt text:

The secret fourth kind is 'we applied a standard theory to their map of every tree and got some suspicious results.'

And here is the chart to follow the progress:

https://taginfo.openstreetmap.org/tags/natural=tree#chronology

We should see a saturation arround 3 trillion trees. (1)

You can easily help achivieving this goal by reworking natural=tree_row and adding single natural=tree into natural=wood areas :) I know, some say this is discouraged, but we really need to map EVERY TREE!

6.6% of trees have the species tag filled out! That's much more than I expected!

[-] redd@discuss.tchncs.de 3 points 2 months ago

Unfortunately most of the species tagged trees are mass imported and not mapped by a real mapper.

I try often to map species or genus but there is no good mobile app for this task yet.

Ah! I would assume the imported sources were decent enough, at least!

I think mapping them might be decent with SCEE. (Might be in normal StreetComplete as well.) You have to enable the quest type as it is disabled by default, but then it offers the quest and even displays recently used values.

That is if you know your stuff, me I would have to have a tree identification book in my other hand, so I guess a specialized app with that functionality would be neat.

@redd @Tyoda https://mapcomplete.org/trees is mobile friendly and supports the species tag. With plantnet, it even uses AI to automatically detect it!

This is literally me.

The person to the right?

A major portion of my professional career has been occupied by the task of "get me a map of every tree"

I feel like https://xkcd.com/2102/ is sort-of about OSM too.
