Add what you verify. Copying species or girth from this overlay into OSM is in effect an attribute import, and importing individual trees is contested in OSM — add what you can check yourself (a crown on imagery, a species on the ground); nothing here is meant to be bulk-copied. OSM circumference is in metres (DBH × π / 100; the City's DBH is in cm). OSM trees with no City tree are not listed: woodlots, back yards and campus trees the City does not inventory.

Empty Thin Covered Sparse

The City's street and park trees (raster layer), counted in 250 m squares. Empty: at least 10 City trees and no OSM tree at all. Thin: some OSM trees, but under 50% of the City trees have one within 5 m. Covered: the rest — there may still be species or girth to add. Sparse: fewer than 10 City trees. Click a cell or a row to list its trees.

Click a row to zoom to the tree, then press O to open it on openstreetmap.org or I in the iD editor (each row has the same OSM · iD link pair; with no tree picked the keys open the cell). A matched tree links to its OSM node, a missing one to the City's position. Matched trees that already carry species and girth are not listed.
