Significant and Regulated Trees

If you are considering purchasing or developing a property or you own or reside in a property that supports a Significant or Regulated Tree, it is important that you understand the regulations that apply to these trees, and what activities can be undertaken and which require Development Approval. We place a strong emphasis on protecting and retaining significant and regulated trees through the Development Approval process. Please refer to the D01. Regulated & Significant Trees Information Guide for further information.

As we recognise the important role of large and aged established trees in contributing to the character, canopy and wellness of our City, we provide financial assistance to support our residents and business their ongoing maintenance through our Heritage Conservation Grants Program. The Program provides financial assistance toward maintenance of Significant or Regulated trees (as defined by the Planning, Development and Infrastructure Act, 2016), or tree maintenance of trees that would otherwise meet the definition of Regulated and Significant trees but have been exempt under the Regulations. You are eligible to claim up to 50% of the total cost of maintenance work (based on the lowest quote) up to a maximum of $1,000 for maintenance works that exceed $500.

To find out more and make an application via the Heritage Conservation Grants page.

Frequently Asked Questions

A ‘regulated tree’ is a tree with a trunk circumference of 2.0m or more, measured at a point 1.0m above natural ground level (in the case of trees with multiple trunks, it is those with trunks with a total circumference of 2.0m or more and an average circumference of 625mm or more, measured at a point 1.0m above natural ground level).

A ‘significant tree’ is a regulated tree with a trunk circumference of 3.0m or more measured at a point 1.0m above natural ground level (in the case of trees with multiple trunks, it is those with a total circumference of 3.0m or more and an average circumference of 625mm or more measured at a point 1.0m above natural ground level).

Pruning branches that encroach on your property can occur without seeking approval, provided it meets the maintenance pruning requirements above. In all other circumstances you will be required to seek Development Approval for any works on your side of the common property boundary. For more information visit Trees and the Law (lsc.sa.gov.au).

Yes, the following conditions will apply:

  • 2 trees must be planted to replace a regulated tree
  • 3 trees must be planted to replace a significant tree

NOTE: The replacement trees cannot be one of the tree species listed as exempt trees or be planted within 10 metres of a dwelling or in-ground swimming pool. Alternatively, attached is information relating to Council’s Urban Trees Fund which you can pay into in lieu of planting trees. This will involve payment of a prescribed amount per tree to Council. Funds collected are then used to maintain regulated trees or establish new trees that will reach a large size.
