MORE than 140 trees will be removed from Commonwealth Park, Kings Park, Acton Peninsula and Anzac Parade over eight weeks by the National Capital Authority.

The removal of 145 trees is part of a tree replacement program, with 150 replacement trees to be planted in mid-2012.

NCA chief executive Gary Rake said all the trees identified for removal are dead or in serious and irreversible decline.

“When a tree dies or reaches a state where normal treatments cannot save it, removal is considered,” Mr Rake said.

“These trees have been assessed by an expert arboriculturist as presenting a hazard that cannot be addressed by other tree management practices.

“New trees will be planted of the same, or similar variety to those that are removed. In cases where a tree has not thrived in the environment, or is no longer suitable for the area, a new species will be selected.”

It is expected further work will occur in the Parliamentary Zone and Dunrossil Drive later this year.

“Canberra’s ageing urban forest needs to be constantly renewed. This work is part of a continuous rejuvenation process,” Mr Rake said.
