​Our research interests

Theme 4: Inventory and Management of Urban Trees​

Image
The fourth research theme aims to improve the inventory and management of urban trees in Quebec. We seek to test a participatory approach that involves citizens in the inventory of private trees, thereby expanding data sets while raising awareness about sustainable management. Additionally, we are exploring the use of drone-based LiDAR to collect LiDAR and hyperspectral data, enabling precise mapping of trees and detailed species classification. The projects in this research theme combine community engagement and cutting-edge technology to provide optimized and sustainable management of urban green spaces.


Project Participatory Science : A Participatory Approach to the Inventory and Management of Private Trees in Quebec

This tree inventory project on private lands, in collaboration with the City of Quebec, the Association Forestière des Deux Rives, the Collectif Canopée, and CERFO, is based on participatory science. Residents are invited to document their trees, contributing to a broader data collection effort. In parallel, data on trees is gathered from businesses and institutions. Additionally, interviews with private landowners highlight their key role in the health of urban forests. This project pushes the boundaries of participatory science in urban forestry while integrating inclusive practices into forest management.

Project Participatory Science : Evaluation of the ecosystem services of private trees in Quebec: Development of an interactive map for the City

This end-of-study project, in partnership with CRAUM, the City of Quebec, the Association forestière des deux rives, the Collectif Canopée and CERFO, aims to characterize, analyze and represent in the form of an interactive map all the data on private trees in Quebec City. Using i-Tree, it evaluates their ecosystem services in order to better understand their role and raise citizens’ awareness of the importance of urban tree cover.
