Project

Identification of Key Biodiversity Areas (KBAs) in Quebec
Key Biodiversity Areas, or KBAs, are areas that contribute significantly towards the maintenance of global biodiversity. KBAs may be applied at the level of either ecosystems or species, and are identified using quantitative, standardised methods that are currently being adapted for use in Canada. My project will focus on the identification of KBAs for rare and at-risk species in Quebec. I will explore alternative methods for modelling the distribution of species for which occurrence data is very limited. In addition, I will use climate change scenarios to explore how these ranges may change in the future, to assess the potential resilience of identified KBAs.
