Tree targets and mapping

We are planting 100,000 trees

Setting targets

We all know the relief of finding a cool spot under a tree or walking along a shady, tree lined street on a hot day.

We need trees for our wellbeing in public areas where there are more hard surfaces, as they provide shade and reduce the impact of radiant heat.

Urban greening is a collection of trees and shrubs that grow within a city, town or a suburb. Providing benefits including shade, cooling, clean air, reduced stormwater runoff and habitat for birds and wildlife to name a few.

We’ve set urban forest targets that will see a 20 per cent increase in both tree canopy cover and urban green cover in our public areas by 2045. This will amount to 100,000 new trees in street verges, waterways and parks by 2037.  We're doing well and so far, our amazing field crews have already planted over 56,000!

As part of our Climate Change Response Plan commitments, we are currently reviewing this target - a report will be presented to Council later this year that will determine next steps.

Tree canopy and thermal heat mapping 

We have previously commissioned tree canopy and thermal heat mapping every few years to help us easily identify where hot spots and gaps have occurred and where targeted planting needs to take place. 

This is now being undertaken centrally by state government for all metro councils. with the most recent mapping released in April 2024 by Green Adelaide and can be viewed online. There are now two sets of comparable data, 2018/19 and 2022 (with the 2018/19 data reprocessed).

While we receive data for our entire council area, it's fair to say that a lot of our regions rural areas are leafy green.  So, it's important that we take a closer look at the data for our urban areas as that's where trees and greening are needed the most. We're undertaking that analysis now and will provide more information here as it become available. 

Some key results for Onkaparinga:

  • our entire council region (urban and rural) has 20 per cent tree canopy cover
  • privately owned land (residential, business and community) makes up 74 per cent of the Onkaparinga region, but contains the lowest amount of canopy cover at 16 per cent.
  • 29 per cent of our area is covered by vegetation with slightly less in our urban areas.
  • local government land has tree cover of 22 per cent and state government 34 per cent.

You can see why as well as our team planting trees in streets and reserves it's so important that you grow trees in your yard, school or business too.  Use the heat and canopy map below to see just where hot spots and gaps are around your property and visit our get planting page to find out about our tree canopy campaign and discover what, how and why it's important to plant and ways to access free trees.
