Do you need a permit?

Rhus Tree is exempt in some councils and protected in others, and several exemptions carry a height limit. Check the table below against the council for your address before assuming a permit is not needed.

How to identify it

Compound leaves with nine to fifteen leaflets that turn a spectacular scarlet in autumn, which is why it was planted. Small cream flowers and clusters of pale waxy fruit. Every part of the plant contains urushiol, the same compound as poison ivy.

Where it grows in Sydney

Scattered through older gardens across the North Shore, Inner West, Eastern Suburbs and Southern Sydney, and naturalised in bushland edges.

Common problems

  • Causes severe allergic dermatitis on contact, including from smoke and sawdust
  • Declared a noxious plant historically and still a notifiable concern in some areas
  • Suckers from roots
  • Frequently misidentified as a harmless ornamental because of the autumn colour

What removal involves

Exempt in most councils on this list. This is genuinely not a DIY removal. Urushiol causes severe reactions through skin contact, airborne sawdust and burning, so full protective equipment and careful waste handling are required. Never burn the material.

Council permit rules, council by council

Status below is for a tree on private land that has passed the council's size threshold. Heritage items, heritage conservation areas, significant tree registers, biodiversity mapping and conditions of development consent override every exemption shown here.

Frequently asked questions

How dangerous is a Rhus Tree?

The sap contains urushiol, the compound in poison ivy. Reactions range from a rash to severe blistering requiring medical treatment, and can be triggered by sawdust or smoke as well as direct contact. It should only be removed by crews equipped for it.

Do I need approval to remove it?

In most councils covered here it is on the exempt species list, including Ku-ring-gai, Hornsby, Lane Cove, Ryde, Inner West, Waverley, Randwick, Georges River, Strathfield and Canterbury-Bankstown.

Important note on council rules

This encyclopedia is a practical guide for Sydney property owners, not legal advice. Council tree rules change, and exemptions are frequently overridden by heritage listings, heritage conservation areas, significant tree registers, biodiversity mapping, endangered ecological communities and conditions attached to development consent. Always confirm the current rules with your council for your specific address before any tree work begins, or ask us to check it for you.
