Canadian Museum of Nature herbarium
The Canadian Museum of Nature herbarium is a major national botanical repository housed in Ottawa, Ontario, associated with the Canadian Museum of Nature. It preserves comprehensive vascular plant, bryophyte, lichen, algal, and fungal collections assembled through expeditions, government surveys, and collaborations with institutions such as the Royal Ontario Museum, National Research Council (Canada), Parks Canada, Geological Survey of Canada, and international herbaria like the Royal Botanic Gardens, Kew, Muséum national d'Histoire naturelle, and the Smithsonian Institution. As a resource for taxonomists, ecologists, and conservationists including those from the University of Ottawa, Carleton University, McGill University, University of Toronto, and agencies like the Canadian Wildlife Service, it supports research on Canadian floras, Arctic biodiversity, invasive species, and climate-change impacts.
The herbarium traces origins to 1881 collections initiated under figures linked to the Geological Survey of Canada and early curators who worked with explorers connected to John Franklin, David Thompson, and surveyors from the Hudson's Bay Company. Through the late 19th and 20th centuries it expanded via transfers from the Ottawa Field-Naturalists' Club, specimens gathered during expeditions led by personnel affiliated with the Canadian Pacific Railway and the Natural History Society of Montreal, and exchanges with global collectors like Joseph Dalton Hooker, Georg Wilhelm Steller, and contemporaries at the Royal Botanic Gardens, Kew. Institutional milestones include incorporation into national cultural frameworks alongside the National Gallery of Canada and administrative shifts during the stewardship of curators who collaborated with researchers at the Bureau of Plant Industry (United States Department of Agriculture) and botanical gardens such as Arnold Arboretum. The herbarium’s collections grew substantially through postwar surveys tied to projects with the National Research Council (Canada) and environmental programs under ministries related to natural resources.
The holdings comprise approximately 1.3 million specimens spanning vascular plants, bryophytes, liverworts, hornworts, lichens, fungi, and algae, with strong representation from Canadian regions: Nunavut, Northwest Territories, Yukon, British Columbia, Alberta, Saskatchewan, Manitoba, Ontario, Québec, Newfoundland and Labrador, and the Maritimes. Significant geographic and taxonomic strengths include Arctic and subarctic floras collected on expeditions associated with ships such as HMS Resolute and scientific teams linked to the Canadian Arctic Expedition (1913–1916), boreal forest assemblages collected during surveys by the Canadian Forest Service, and prairie records gathered in coordination with the Canada Agricultural Research Institute. Collections also include historical specimens exchanged with the Muséum d'histoire naturelle de Genève, the Natural History Museum, London, and the Botanical Garden of Berlin-Dahlem.
The herbarium supports taxonomic revisions, floristic surveys, and monographic studies by staff and collaborators from institutions like Royal Botanical Gardens, Ontario, Harvard University Herbaria, University of British Columbia, Université Laval, and international partners at the Royal Botanic Garden Edinburgh. Research outputs address systematics of families such as Poaceae, Asteraceae, Ericaceae, Gramineae (historic treatments), and cryptogams including Bryophyta and lichenized fungi documented by specialists linked to the Canadian Botanical Association and the International Mycological Association. Collections underpin conservation assessments used by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC), ecological studies with the Canadian Wildlife Service, and paleobotanical comparisons with specimens from the Canadian Museum of History and university paleobotany groups.
Specimens are housed in climate-controlled cabinets within archival facilities comparable to practices at the Smithsonian Institution National Museum of Natural History and the Royal Botanic Gardens, Kew. Preservation protocols align with standards promoted by organizations such as the International Association for Plant Taxonomy and the Biodiversity Information Standards (TDWG). Digitization initiatives have partnered with the Canadian Biodiversity Information Facility and international platforms like the Global Biodiversity Information Facility, enabling high-resolution imaging, transcribed label data, and georeferencing supported by collaborations with the Atlas of Living Australia and university GIS groups at McMaster University and Queen's University. Molecular sampling programs coordinate with sequencing centers including the Canadian Centre for DNA Barcoding and university genomics cores.
Public engagement is delivered through exhibits at the Canadian Museum of Nature alongside outreach involving school programs tied to the Ontario Science Centre curriculum frameworks and citizen-science platforms such as projects associated with the Nature Conservancy of Canada and community groups like the Ottawa Field-Naturalists' Club. Educational collaborations with the Royal Ontario Museum, Canadian Wildlife Federation, and university extension programs provide workshops on plant identification, herbarium techniques, and conservation priorities. Outreach includes traveling displays, contributions to national biodiversity panels coordinated with the Canadian Heritage portfolio, and participation in events such as Canada Science and Technology Museums Corporation initiatives.
Type specimens and historically important collections include material collected by explorers affiliated with the Canadian Arctic Expedition (1913–1916), types associated with taxonomic descriptions published in journals tied to the Canadian Journal of Botany and monographs overseen by curators collaborating with the Royal Botanic Gardens, Kew and the Muséum national d'Histoire naturelle. Noteworthy specimens document first records for regions such as Labrador, the Queen Elizabeth Islands, and alpine populations from ranges like the Rocky Mountains and the Laurentian Mountains. The herbarium houses holotypes, isotypes, and syntypes critical for nomenclatural stability referenced by international botanical authorities including the International Plant Names Index and researchers at the Royal Botanic Gardens, Kew.
