The project will focus on understanding how three threatened lichen species (Peltigera hydrothyria, Anzia colpodes, and Pannaria lurida) within Atlantic Canada are distributed and impacted by both the environment and humans. A statistical analysis and field collection will be completed to determine if the models used for each species accurately predicts the presence of the lichen. Detailed documentation will be provided to aid in creating a modelling standard and to facilitate the study being repeated.
