Claims, one by one

The text below is copied verbatim from the published record. Each claim names the source dossiers that carry it; caveats stay attached to the claim they qualify.

Claim 1 clm-459e2bc9f12ed03d quantitative

The 2012–13 tree census recorded all of the City of Melbourne's roughly 70,000 street trees — species, size, condition and an estimate of each tree's useful life — and published them as the public Urban Forest Visual map

Published field: impact · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport
What the mapping says: The impact states the census figure is corroborated by AIPH's green-city case study.
Caveat: The entry's lesson notes the project's fame rests on the email-a-tree turn, which is well documented but is engagement, not a proven climate outcome.

Known limits of this passport

Publisher names and source languages have not yet been classified; domains are recorded without guessing.
Existing source notes are descriptive locators, not page- or paragraph-exact citations.
A missing archive, publication date or content hash is shown as null rather than inferred.
The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
