ENVIRONMENT: Beetles will likely wipe out ash trees across city ...insideTORONTO.com - Toronto,Ontario,Canada
Toronto's emerald ash borer infestation can't be held back and will kill nearly every ash tree in the city over the next decade, Toronto's Urban Forestry director Richard Ubbens says.
"These things can travel 25 kilometres, no problem," he added. "When you see the outward effects, the tree is dying already."
The beetles pose no danger to humans but an estimated six per cent of Toronto's tree canopy is ash, a hardwood that plays an important role in the regeneration of forests.
