Queen's Jubilee Planting and Tree Removal

Share on Facebook Share on Twitter Share on Linkedin Email this link

The City of Onkaparinga recently received $20,000 from the Australian Government to plant trees to honour Her Majesty Queen Elizabeth’s 70 years of service.

The Queen’s Jubilee Planting will consist of planting 50 new native trees as well as irrigation to ensure their strong survival. Click here to see some examples of the native trees being planted.

The western verge section along Main South Road, adjacent Knox Park has been chosen for the Jubilee planting due the location being along a major road and close to the Knox Park sports park, ensuring the plantings will be seen and enjoyed by many.

The existing trees in the western verge from Flaxmill Road to the south of Knox Park, have been failing over the past few years. An independent audit was undertaken where it was found 23% of trees were in either poor health or dead and 54% have poor structure, suggesting that whole tree failure is highly likely in storm events.

A staged tree planting plan is being developed providing an opportunity to replace the trees that have fallen or are in poor health, with more appropriate tree species. The Main South Road tree planting program will begin with the Jubilee tree planting alongside a section of Knox Park. View the Main South Road tree planting program here.

Following a further on-site assessment, 11 trees in this section were identified for removal to make way for the new plantings. Click here to view the location maps.

Of the 11 trees that are proposed to be removed, three are regulated, one of which is in very poor condition. A summary of the condition of these trees is provided below:

  • All three trees are Western Australian Eucalyptus occidentalis
  • Tree 1 (see plan) is in poor health and has no retention value or useful life (nil years). This tree poses a high risk to vehicles and pedestrians.
  • Tree 2 is in fair health and has a useful life of 1-5 years.
  • Tree 3 is in good health but has overextended branches biased to the west and has a useful life of 5 to 10 years. It is however exposed by the failure and removal of adjacent trees to the east.
