Do you need a permit?

Blackbutt is a protected tree in effectively every council Pro Climbing Tree Services covers. Expect to need a tree permit, or a development application where the property is heritage listed or in a heritage conservation area.

How to identify it

Named for the dark rough fibrous bark on the lower trunk, which gives way abruptly to smooth white or cream bark on the upper trunk and branches. Leaves are sickle shaped and glossy on both surfaces. Clusters of white flowers appear from spring to midsummer.

Where it grows in Sydney

A dominant forest tree through the Northern Beaches, Hornsby Shire and the northern parts of Ku-ring-gai, especially on sandy and shale influenced soils. Very common on bush fringe properties in Belrose, Terrey Hills, Frenchs Forest, Hornsby Heights and Berowra.

Common problems

  • Exceptional mature height close to dwellings
  • Sudden limb failure in summer
  • Fibrous bark contributes to ember attack risk in bushfire prone areas
  • Continuous litter load into gutters and tanks
  • Often part of a mapped endangered ecological community, which removes many exemptions

What removal involves

A technical removal in most suburban settings. Bush fringe blocks frequently sit inside biodiversity mapping, so the assessment usually needs to cover ecological value as well as tree condition. Where the property qualifies for the 10/50 Vegetation Clearing scheme the pathway can be different, so check the RFS 10/50 tool for the address first.

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

Does Blackbutt need a permit to remove?

Yes in every council covered here. It is a protected native and is not on any exempt species list. Bush fringe properties may also trigger biodiversity or endangered ecological community controls on top of the standard permit.

Can I remove a Blackbutt under the 10/50 rules?

Only if the property sits inside a 10/50 Vegetation Clearing Entitlement Area and the tree is within 10 metres of an external wall of the home. Check the NSW Rural Fire Service 10/50 tool before assuming it applies.

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.
