Tree Regeneration along Dunrossil Drive
18 March 2013
The National Capital Authority (NCA) will begin removing Pine trees along Dunrossil Drive next month as part of an ongoing tree replacement programme.
The Pine trees will be removed in two stages. The first stage will commence on 8 April 2013 and the second stage is scheduled for 2015/16. Tree replanting will occur 12-18 months after each removal stage.
NCA Chief Executive, Mr Gary Rake said many of the trees are dead or dying.
'The grand avenue is the product of a deliberate planting scheme developed and implemented by Charles Weston, who was responsible for the early afforestation of Canberra. It is believed the Pine trees along the entrance to Government House were planted in 1926-27,' Mr Rake said.
'Many of the trees are now dead or in serious decline and have been assessed by an expert arboriculturist as presenting a hazard. The tree replacement programme will ensure the avenue will be enjoyed by generations to come,' he said.
The replanting of Dunrossil Drive will retain the existing central avenue of Elm trees, surrounded by a second row of mixed trees (Pine and Oak), with an evergreen tree backdrop. The backdrop will be formed by creating a third row using an evergreen species of Oak and then replanting the Pine plantation on the outside of the avenue.
The third row of evergreen Oak trees will create greater consistency along the avenue, while increasing the separation between the Pine trees and the road. This increase in distance between the road and Pine trees is intended to reduce the risk associated with Pine tree failure and also allow for more frequent replacement of the Pine trees without affecting the vista from the road.
It is anticipated the removal of pine trees will take three weeks to complete. This involves the use of heavy machinery. Remediation of the site is expected to take a further 12 weeks.
Minimal impact is expected on road users, pedestrians and cyclists during the project. Short-term delays will occur infrequently on the cyclist and pedestrian path, however these will occur outside peak periods.
