Regulated and significant trees

A regulated tree is any tree in metropolitan Adelaide, Adelaide Hills Council townships and parts of the Mount Barker Council with a trunk circumference of 2.0 metres or more (measured at a point 1.0 metre above natural ground level).

In the case of trees with multiple trunks, regulated trees are those with trunks having a total circumference of 2.0 metres or more and an average circumference of 625 millimetres or more (measured at a point 1.0 metre above natural ground level).

A significant tree is a regulated tree in metropolitan Adelaide, Adelaide Hills Council townships and parts of the Mount Barker Council with a trunk circumference of 3.0 metres or more (measured at a point 1.0 metre above natural ground level).

In the case of trees with multiple trunks, significant trees are those with trunks having a total circumference of 3.0 metres or more and an average circumference of 625 millimetres or more (measured at a point 1.0 metre above natural ground level).

Some trees may be exempt from regulated and significant tree controls because of their location or their species.

Contact your local council to find out if:

  • the regulated and significant tree controls apply in your area
  • a tree is listed in the council's development plan
  • a tree is exempt from controls.

What activities are not allowed with regulated and significant trees

Regulated and significant trees must not be damaged. Tree damaging activities include:

  • tree removal
  • killing or destruction
  • lopping
  • ringbarking or topping
  • severing of branches, limbs, stems or any other substantial damage to a tree including its root system.

It is necessary to obtain development approval from your local council in order to undertake any of these activities.

Maintenance pruning that is not likely to affect the health or appearance of a regulated or significant tree does not require development approval.

Contact your local council before undertaking any work affecting a regulated or a significant tree to find out what can be undertaken and whether any exemptions apply.
