The City has been mapping and monitoring tree canopy cover for the past seven years which has informed the development the Urban Forest Plan. Using high-resolution airborne multispectral imagery, a canopy area is analysed to calculate changes to 'significant canopy'. Significant canopy is defined as tree canopy cover that's taller than three metres and has an area larger than 20m².
To increase urban canopy cover, the City's Council set a target of an average of 18 per cent canopy cover across the City by 2040.
Key facts
- Over the past seven years, tree canopy cover has fallen by nearly 1.5 million m². Two-thirds of this loss has occurred on residential land, mostly as a result of development
- Although the City plants 10,000 new trees each year, this is not enough to replace the canopy being lost
- If we do not act now, canopy cover will be reduced by up to 50 per cent in suburbs with high rates of development
- An Urban Forest Plan will help us to develop solutions to slow down canopy loss and increase the number of new trees being planted
- Extensive mapping and monitoring indicates the City has 12.4 per cent average tree canopy cover across all land types
- Mapping and monitoring reveal canopy loss rates have increased over the past seven years with a combined total of over 1.5 million m² of tree canopy lost
- 68 per cent loss from residential land and 12 per cent loss from verges.
Residents are eligable for free trees to plant in their garden through the Free Tree Program. Registrations for this program will open in the coming weeks.
