Nominate significant trees

Council is updating the current significant tree register and seeking assistance from community to update the list. This can be done by nominating a tree in Casey that deserves special protection due to its remarkable size, age, rarity, ecological importance, or cultural and historical value.

These trees can be individual specimens or groups and may be located on either private or public land. If residents believe that a tree deserves recognition for its unique qualities—whether in their own garden, someone else’s, a nature strip, or a public park, it can be nominated.

By nominating a tree, residents help promote, share, and safeguard valuable trees within the community.

To nominate a tree, fill out the Significant Tree Nomination Form, online or download a hard copy and either email, post or drop in to one of our customer service offices.

  • Online via the form on this page
  • Email Vandana Rama, Head of Sustainability & Environment at vrama@casey.vic.gov.au
  • Phone 9705 5200
  • Post to City of Casey, PO Box 1000 Narre Warren, Victoria 3805

Materials can be provided in printed format upon request.

Nominations close 11 May 2025 (5:00PM)

Steps in the nomination process

When you nominate a tree for protection, we assess it based on several factors:

  • Aesthetic value: A tree of outstanding aesthetic significance.
  • Age and vulnerability: A tree which is particularly old or vulnerable.
  • Curious growth form: A tree which exhibits a curious growth form or physical feature such as abnormal outgrowths, natural fusion or branches, severe lightning damage, or unusually pruned forms.
  • Historical value: A tree commemorating a particular occasion (including plantings by Royalty) or having associations with an important historical event. Significant place associations. Social significance.
  • Horticultural value: A tree which is of horticultural or genetic value and could be an important source of propagating stock, including specimens that are particularly resistant to disease or exposure. Association with scientific/technical innovations.
  • Indigenous culture: A tree associated with Indigenous activities.
  • Location or context: A tree which occurs in a unique location or context and so provides a contribution to the landscape, including remnant native vegetation, important landmarks, and trees which form part of an historic garden, park or town.
  • Outstanding example of species: A tree that is an outstanding example of the species.
  • Outstanding size: A tree outstanding for its large height, trunk circumference, or canopy spread.
  • Rare or localised: A tree or species or variety that is rare or of very localised distribution.

If you think the tree will fit one or more of the criteria, continue to the next step.

Nominate a significant tree via the online Significant Tree Nomination Form.

Note: If you’re nominating a tree on private property, we encouraged you to let the property owner know that you’re nominating their tree. There is a section in the nomination form where you can include their details.

Within 28 days of receiving your nomination Council officers will undertake a desktop assessment to determine if the nomination fits the criteria.

Note: This may take longer if it is determined that a site inspection is required (subject to government restrictions). Council officers will contact you if this is required.

Nominations that proceed through to step 5 will be referred to an arborist for assessment. It will be at this stage that it will be confirmed whether the tree or group of trees are significant and if they warrant protection.


Council will prepare a final list of trees recommended by the arborist to proceed to a Planning Scheme Amendment.
