Two diseased and dying trees will be removed from Hyde Park North in Sydney.
One of the trees is a dead Holm Oak (Quercus Ilex) and has been declining in health for several months.
The tree has tested positive for two diseases - Phytophthora cinnamomi and Pythium. Phytophthora causes root-rot and eventual death to a wide variety of native and exotic plants and is one of three diseases also affecting the large Hills Fig trees in Hyde Park.
The second tree is a semi-mature Sydney Blue Gum (Eucalyptus saligna) located at the northern boundary of Hyde Park North on the western side of the Central Avenue.
The Sydney Blue Gum is planted in a garden bed and has a restricted root volume, with the tree slowly declining and dropping small dead branches for the past 12 months.
A study in 2006 found the two trees were among as many as 230 trees of the 600 trees in Hyde Park that were diseased and dying and must be removed over the next 15 years to ensure public safety.
The trees will be replaced with new, mature replacement trees as part of a $37 million plan to upgrade Hyde Park and gradually replace diseased and dying trees and soil.
Non-infectious parts of the two trees will be mulched for use in other inner city parks.
All infected material taken to landfill to ensure the diseases are not spread.
