As Curator of Botany at the museum, Jennifer Doubt keeps tabs on over one million specimens of Canadian wild plants.
- Bryophyte ecology, floristics, taxonomy.
- Assessment, monitoring, recovery and conservation of rare plant species and plant diversity.
- Botanical training.
- Herbarium management.
- M.Sc., Bryophyte Ecology, University of Alberta, 2001.
- B.Sc., Botany, University of Guelph, 1995.
First and foremost, Jennifer Doubt is the Curator of the National Herbarium of Canada here at the Canadian Museum of Nature. That means she works to safeguard and document over one million specimens of Canadian wild plants, and ensures that Canadian and international researchers, educators and enthusiasts can access and learn from the specimens.
Jennifer is an expert on Canadian mosses and their plant relatives. Mosses blanket much of Canada—especially in the Arctic and boreal regions—and make life possible for thousands of animal and plant species by providing essential food and habitat. Jennifer works to document and protect Canada's mosses through her own research and collaborations with commercial, academic and government organizations. Her work produces moss identifications, surveys and educational resources and reports on topics such as rare species' status and recovery, species inventories and survey methods.
