Résumé: The objective of this research project is to conduct fieldwork to determine the population size, distribution, and habitat of Nahanni Aster. Fieldwork will involve helicopter access to hotspring habitats. Presence/absence of Nahanni Aster will be recorded, stems counts will be conducted, and habitat and potential threats will be described. There are possible opportunities to promote the Nahanni a...
