Get Started Guide
New to tree counting? Follow these simple steps
Spot a tree
Look for mature or ancient trees in your area. Anything with character, size, or clearly old age is worth recording.
Check if it's accessible
Make sure it's on public land or visible from a public space. Don't trespass!
Get your location
Open the app and tap "Get Location" to capture GPS coordinates automatically.
Take a photo
Capture the full tree or a distinctive angle. This helps with identification and creates a visual record.
Measure the girth
Wrap a tape measure or string around the trunk at chest height (1.5m). Record in centimetres.
Select the species
Choose from the dropdown. Not sure? Make your best guess or use the species helper tool.
Save & sync
Hit save. Your tree is stored locally and will sync when you're back online.
Repeat!
Keep exploring and recording. Check the leaderboard to see how you rank!
Tree Logging Guidelines
Please read and accept these terms before recording trees
- Public Land Only: Only record trees on public land, accessible footpaths, or areas with public access. Never trespass on private property without permission. If a tree is on private land but visible from a public space, you may record its details visually, but do not enter private property.
- Safety First: Prioritise your safety. Do not enter dangerous areas, climb trees, or take risks to measure or photograph trees.
- Respect Privacy: When taking photos, avoid capturing people, vehicles, or private properties. Focus only on the tree.
- Accurate Measurements: Measure girth at chest height (1.5m). Provide accurate species identification to the best of your ability.
- Environmental Care: Do not damage trees or surrounding vegetation while measuring or photographing.
- Data Sharing: Information you submit will be shared publicly to contribute to community tree mapping efforts.

The Biodiversity Index is a simple score reflecting how ecologically valuable a tree is, based on the wildlife it supports, its age value, pollinator role, and its potential as a habitat/corridor.
This highlights estimated benefits such as CO₂ absorption, NO₂ filtering, rainfall interception, and shade provision.
Wildlife diversity varies by species and age. Older trees typically support more creatures through deadwood, cavities, and established bark ecosystems.
Historical context helps us appreciate the tree's longevity. These events occurred around the time this tree was a sapling.
