New shade of green for the city | green streets |

It's out with the old and in with a new tree canopy for Melbourne. 

Now that the solitary, gangly pine tree - 30 metres tall and all that remains of the celebrated Takata Matsubara forest in north-east Japan after the tsunami last March - is dying, all hopes are being pinned to grafting the tree and raising seedlings.

The pine, which until 10 months ago was just one amid 70,000, has come to mean more than its lean trunk and thin crown, something more than its materiality. It has become a symbol of hope and, for a time at least, survival.
Just as trees provide the bones of many private gardens, they help set the tone of the wider public landscape. Like the Japanese pine, this can be because of the emotions we pin to them as well as their physical presence.

Trees - ever-changing and ultimately dying, as they do - can never be viewed as a static part of the landscape and, under the strategy, the emphasis will be on increasing biodiversity and introducing a much wider range of plant species (both natives and exotics) with varying life expectancies, growth rates and growing conditions. Green roofs, walls and balconies will also play a bigger role...
