OAC-BIO Herbarium

Latest version published by University of Guelph on Feb 15, 2016 University of Guelph

The BIO Herbarium at the University of Guelph houses approximately 100,000 (image data for 65,535) herbarium specimens, collected from all around the world. The collection provides excellent coverage in ethnobotanical notes and houses vouchers for the Flora Ontario Integrated Botanical Information System (FOIBIS). The collection also contains DNA Barcoding vouchers for the Center for Biodiversity Intitute of Ontario (CBG) of the Biodiversity Institute of Ontario. BIO Herbarium is committed to making this important collection more accessible to botanists and others, wherever they may be, for use in their own projects: particularly in biodiversity, conservation, sustainable development and systematics. To this end we have developed HIMS, which contains labelled information and images of all the specimens at the BIO Herbarium.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 65,535 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Geographic Coverage

The Ontario Agricultural College was instrumental in establishing the OAC Herbarium and hence the collection reflects this history with an impressive collection of weeds (Pre -1800). Most of these collections are vouchers from current research projects including the Flora Ontario project. However, there are smaller collections within the herbarium that arm from research initiatives across the globe.

Title OAC-BIO Herbarium Information Management System (HIMS)
Funding Canada Foundation for Innovation

The personnel involved in the project:

Subramanyam Ragupathy

Sampling Methods

Floristic diversity; Weeds of Ontario collection; DNA barcoding collections- collection, identification, preparation of typical herbarium vouchers, accessing in to OAC-BIO herbarium by the respective project investigator.

Study Extent The Herbarium collection has increased from 85000-128000 specimens in the last three years. Most of these collections are vouchers from current research projects including the Flora Ontario project. Dr Newmaster arranged for the donation of several specialized collections from the Canadian National Museum, Royal Ontario Museum, Royal Botanical Gardens, University of Alberta, University of British Columbia, Canadian Forest Service, Botanical Research Institute of Texas and the Missouri Botanical Gardens. Starting in 2006, the OAC Herbarium will become the repository of all plant vouchers for the Canadian Barcode of Life Consortium, which just received funding from Genome Canada ($630,798 for plants) to barcode plants in Canada. This will include the archival of herbarium vouchers, preserved leaves in silica gel and the extraction of each specimens DNA for cryopreservation.
Quality Control Records are edited on an ad hoc basis.

Method step description:

  1. Data are entered into the Herbarium Information System (HIMS) and some records determined by taxonomic experts.
