Paul Bolan, vice-president of Bioforest Techonologies Inc. – the company that helped develop TreeAzin™ – disagrees with the city’s removal plan. He says the science has changed and the city’s strategy is out of date. “Management options available before 2009 are to a large degree irrelevant,” he said.
Sixty per cent of the city’s ash trees are privately owned.
Any property owner with an ash tree on his or her property will be responsible for its treatment and eventual removal if it dies. Property owners are not required to remove healthy ash trees, but once one dies and begins to decay, which seems certain based on accounts by city officials, the owner must remove the tree before it becomes a hazard.
Removal of a tree can cost a private citizen anywhere from $750-$1500. TreeAzin™ on average costs about $150-$225 per a treatment for a tree about 30 centimetres in diameter.
