Testing a process-based phenology model for improved forest protection during spruce budworm outbreaks
The proposed project would develop a shoot phenology model and identify tree physiological adjustments according to latitude, altitude, and species that rule the tree phenology. The model will able to provide strong predictions of synchrony between bud-shoot and insect development from long-term observations. This model will be used on a large scale in Quebec and has the potential to optimize the timing of annual treatments to reduce the severe impacts of spruce budworm defoliation in boreal forests. This project is expected to influence the short-term policies of forest protection management against spruce budworm in Quebec’s province.
