L’Île de Montréal has twice as many species of trees we thought, discovered a researcher, who also found that there are much more in the most wealthy sectors.
“My greatest surprise was to note that there are large differences between the districts. The more a sector is favored, the more trees there are, both on private land as on public sites, ”says biologist Emma Bacon who presented her results at 92e Congress of the French -speaking Association for Knowledge (ACFAS) which is held this week at the School of Higher Technology in Montreal.

The Notre-Dame-de-Grâce district (NDG), for example, has three times more trees and twice as many species (142 against 66) than Parc-Extension. There are 2078 trees per 200m plot at NDG against 642 in Parc-Extension, calculated the master’s degree in Concordia University.
With her team, she identified and measured one by one by one more than 28,000 trees, both on private land and in parks and institutional spaces such as businesses and schools.
His observations, still unpublished, reveal that the Ile de Montréal has 317 species, almost twice as much as thought.

His project included data collection in 22 sectors of the island, from Pierrefonds to Pointe-aux-Trembles.
“The longest was to knock on the doors to ask people permission to list their trees,” she explains Journal.
Residents were very welcoming everywhere.
“Trees’ inventories are based on public land; We generally do not know what people cultivate in them, in their yard for example, ”explains the research co -director of Mme Bacon, Carly Ziter, Professor at Concordia University.

Precious services
Originally from Windsor, Ontario, Emma Bacon wanted to study vegetation in an urban environment, which is why she chose to conduct her higher education in Montreal.
“Trees do us precious city services. They decrease the effects of heat, host a multitude of birds and insects and do us good in morale, “explains the biologist.
