Dead trees

The City of Calgary will replace dead trees along Stephen Avenue this weekend for the second time in as many months.

The white ash trees planted just two months ago along the pedestrian mall have failed to thrive and need to be replaced.

The city's head arborist, Jill-Anne Spence, said she had high hopes for the species. She said they were nurtured for six years before being transplanted.

"It's discouraging," she said, "we're managing a living asset so it's never one thing that causes them to go into decline."

Spence said she suspects the weather is the culprit for the trees failure to thrive.

City crews will be out on Stephen Avenue this weekend, removing the dead trees and replacing them.

According to the city, the cost of replacing 37 trees this time will be $6,000 to $7,000 as it already owns the trees and there is less preparatory and cleanup work involved.  

Two months ago, the parks department spent $50,000 to purchase and replace 53 trees on Stephen Avenue.
