About 60 per cent of young trees planted as part of a green initiative in Montréal-Nord died because the borough didn't properly water them, according to the city's auditor general. The trees were part of the city's Un enfant, un arbre (One child, one tree) initiative, which began in 2013. Citizens can apply to have a tree planted in their neighbourhood to celebrate the birth or adoption of a child. The report, released Tuesday, said "a lack of sufficient watering" meant that 60 per cent of those trees, planted in public spaces in Montréal-Nord, died, representing "a loss of both investment and benefits to the ecosystem."
