Inventory of pollinators in power transmission rights-of-way

Hydro-Québec (HQ) – 2018-2019

The mandate consists of carrying out an inventory of pollinating insects present in the power transmission right-of-way. This work aims to verify whether changes in habitat quality for pollinators in the right-of-way and in the immediate environment lead to differences in the abundance and diversity of pollinators. The results obtained will provide input on how to optimize developments on and off the right-of-way to favour pollinators.

The inventory sites are located in two Hydro-Québec transmission rights-of-way, one in Laval and one in Montréal. They were selected using a habitat quality analysis and comparison tool developed by T² Environnement.

The study will document pollinator populations using the rights-of-way over three seasons: spring (May 2019), summer (July 2019) and fall (September 2018), and establish a direct link with the melliferous plants present in the various inventories.

This study differs from those usually carried out by Hydro-Québec on biodiversity in power transmission right-of-way. This is the first time that a group of insects has been inventoried and the inventory has been carried out in an urban environment. In addition, overall, very little research documents both the pollinators present in a location and the plant species on which these insects feed.
