The City of Unley is known for its wide, tree lined streets.

Unley's Street Trees

Council have an arboriculture team who look after established trees and nurture young trees in Unley’s streets and reserves.

The City of Unley covers an area of about 14 square km where 26,000 to 27,000 public trees grow. There are around 23,000 street trees and 3,000 to 4,000 trees in parks and reserves.

We encourage you to water your street trees during times of hot weather. Please contact us if you believe the trees need additional care.

A typical Unley streetscape features beautiful leafy tree borders. 69 per cent of species are exotic, 30 per cent are native and 1 per cent are indigenous to the local area.

Most of Unley's street trees are mature, with 200 to 300 new trees planted each year.

The estimated economic value of street trees in Unley is $150 million.

Tree Tags in Parks

Council are using tree tags to highlight the benefits of trees and increase awareness of their value to the community.

Each tag has information specific to its tree such as species name, height, ability to remove pollution from the air and more.

There are 80 tags spread across the following six locations:

  • Goodwood Oval - Curzon Avenue, Millswood
  • Page Park - Corner Cross Road and East Avenue, Clarence Park
  • Unley Civic Centre - 181 Unley Road, Unley
  • Heywood Park -  Addiscombe Place, Unley Park
  • Windsor Street Linear Trail - Windsor Street, Fullarton
  • Fullarton Park - Corner Fisher Street and Fullarton Road, Fullarton

Trees receiving the tags were selected with the help of local volunteers.

All tags have been printed on 100% recycled plastic materials to ensure they are weatherproof.

Please head out and find some tags and learn about the wonderful things our park trees provide us!


Around Powerlines

Vegetation needs to be cleared from around powerlines to avoid power outages through damaged lines.

It is a legal requirement that electricity network operators maintain safe clearance zones around powerlines and trees. Residents are also responsible for pruning trees around lines within their own private property.

For detailed information on vegetation clearance near powerlines visit the SA Government’s website.

Ridge Park Trees

Multiple Benefits of Trees at Ridge Park

A risk assessment of the trees at Ridge Park was recently undertaken, and while we were there we ran the information through i-Tree Eco assessment to learn more about how our trees benefit the park and the ecosystem services they provide.

Street Tree Removal

The City of Unley recognises the important contribution trees and vegetation make to the community.

These assets support flora and fauna, address the impacts of climate change, add character to our streetscapes and increase property values.

We commit significant resources, and encourage the community to play an important role, to ensure our City has the best possible streetscapes and reserves.

Trees are not permanent fixtures though. There comes a time in their life cycle when trees decline to a stage where they must be removed or when disease or damage means that replacement is the most responsible long-term approach.

In our urban environment, the removal of trees is sometimes necessary for property development or the installation of infrastructure.

To lodge an application for the removal of a street tree, please complete a Street Tree Removal Form.

For further information, view Council’s Vegetation Management Policy which aims to ensure these assets are protected and enhanced for current and future generations.
