Ash Tree - Doomed?
This is a 30+ year old Ash tree that grows in the city owned boulevard near my home in Toronto.
Still seen in the dormant winter stage here, it survived the latest street culling a few months ago targeting victims of the Emerald Ash Borer infection. Apparently, All ash trees in the city are at risk of dying from this infestation.
A recent City tree canopy study estimates that there are 860,000 ash trees in total on public and private lands. The initial areas of infestation in Toronto were detected in 2007, afterwards spreading and expected to be killing most ash trees in the City by about 2015 - 2017.
The Emerald Ash Borer is an introduced insect pest from Asia that attacks and kills all species of true ash trees (genus: Fraxinus) by feeding beneath the bark and disrupting the flow of water and nutrients within the tree.
UPDATE: This tree was cut down and shredded along with several (5) other ash trees on the same street on August 28, 2012. Counting the rings, they indicated this tree had seen 33 - 35 summers. On the positive side, the Basswood trees that were planted on the street at the same time and alternating with the ill-fated Ash seem to be flourishing.
