Urban Forest Visual & Email-a-Tree
This overview was generated with AI from the public sources listed below and checked against them before publication. It has not had a complete human fact-check — treat it as a starting point and follow the sources.

Melbourne mapped all 70,000+ street trees with individual IDs, species and health data in its Urban Forest Visual — and citizens started emailing love letters to their favourite trees instead of just fault reports. Data-driven greening with an unexpectedly human side.
what does this mean?
The strongest source is an independent non-academic evaluation: an audit office, a government or EU review, or an NGO. It grades who did the looking — not how well the project went. All four grades →📊 Impact
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 (City of Melbourne; corroborated by AIPH's green-city case study). That inventory is the evidence base for the Urban Forest Strategy's goal of doubling public-realm canopy cover from a 22% baseline to 40% by 2040, which the city's own modelling says needs at least 3,000 new trees planted every year (City of Melbourne, official target). Giving every tree an ID also meant giving it an email address for fault reports; instead, thousands of residents — and writers from beyond Australia — sent the trees messages of thanks, apology and affection, and council staff reply in each tree's voice (Biophilic Cities case study, as of 2024).
🎓 Lesson
Melbourne set out to build an arborists' database and accidentally built a public relationship with the canopy. The measurable core is prosaic and solid — a tree-by-tree inventory driving a planting programme toward a dated canopy target — while the fame rests on the 'email-a-tree' turn, which is well documented but is engagement, not a proven climate outcome. The transferable point: publishing per-asset data with a way for people to talk back can turn a maintenance system into civic attachment at almost no extra cost.

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.

A tree with an ID number: four registers, four things the number is for
Giving every tree a record is the same technical act everywhere. What differs is what the record is then used for — and in one case the register turned out to audit the campaign that created it.
