July 2012
Ash tree treatment and removals continue throughout identified areas of
the city. Efforts are being made, wherever possible, to replant with
suitable replacements as soon as possible. Right now
We need to target trees that can be saved.
In recent years, options have been developed that will allow preservation
of trees in the short term. In other words, treating ash trees
bi-annually could be less expense than removing them.
We strongly encourage the preservation of ash trees wherever possible to
maintain our status as the Forest City.
A large percentage of London's treatable ash trees are located on private
property. Ash trees which are still healthy and structurally sound can be
protected if residents know about them and choose to treat them.
It is recommended you assess your trees immediately to determine
which course of action is appropriate. These could include:
- injecting the
tree if it's determined to be a candidate for treatment;
- removing the tree
before parts of it become hazardous;
- removing the entire tree when it dies. Dead trees are brittle and
most prone to breakage and causing damage (this last scenario will likely put you and your neighbours
at greatest risk and be the most expensive action you can take).
The sooner you begin treatment, the better chance you have of saving your
tree. If your trees show signs of infestation, you are encouraged to have
the tree removed before it becomes dead and brittle and the costs go up.
June 2011
Throughout the early months of 2011, City of London crews examined trees on streets and
in parks to determine the extent of the Emerald Ash Borer (EAB) in the city.
It became evident that EAB is all across London - with the greatest
concentration in the city's north and east.
This insect has the potential to kill all of the city's ash trees over a
short period of time - it is anticipated within 7 to 10 years, left
untreated, most of our ash trees will be dead.
