TRTE Herbarium (TRTE)

Study Extent

Digitization of specimens from the TRTE Herbarium with a strong representation of sedges (genus Carex), mainly from eastern Canada and, to a lesser extent, from elsewhere in Canada and the United States.

Sampling

All specimens were manually digitized using an EPSON Expression 10000XL flatbed scanner into .jpg files. Data from these high resolution scans were then entered into the database.

Quality Control

Database entries were corrected manually.

Method steps

1. Each specimen was labelled using a unique barcode (ex. TRTE0000001). These specimens were then scanned using an EPSON Expression 10000XL scanner. Information from the labels on the specimens were then entered manually into the database.

The dataset is primarily composed of the entire Carex collection within the TRTE Herbarium which have all been digitized and databased.

Geographically, the herbarium’s main focus is on vascular plant specimens from Ontario, but important collections are also available from Québec and the Canadian high Arctic. Small quantities of specimens are available from all other regions of Canada, United States, Western Australia, New Zealand, and West Africa (Nigeria, Sierra Leone). There are also some smaller collections within the herbarium that stem from research initiatives across the globe.
