Biodiversity Museum & Herbarium Curator
Barbara J. Hellenthal

Research Interests:

Collaborator (2014 - Present) in ongoing efforts that use natural history museum specimens to document the introduction and spread of exotic species through the Great Lakes Region. Notre Dame’s Museum of Biodiversity and Greene-Nieuwland Herbarium is part of a network of herbaria and zoology museums from among the Great Lakes states and provinces of Canada that are documenting the occurrence of these species and tracking their introduction and spread by providing online access to individual specimen collection data and images for these organisms from their museums.

Collaborator (2011 - Present) in the Global Plants Initiative (formerly JSTOR Plant Science), a community of over 300 museums from 80 countries that are building a world-wide online database that features more than two million high resolution plant type specimen images and other foundational materials from the collections of hundreds of herbaria around the world. It is an essential resource for institutions supporting research and teaching in botany, ecology, and conservation studies. Through Global Plants, herbaria can share specimens, experts can determine and update naming structures, students can discover and learn about plants in context, and a record of plant life can be preserved for future generations. To date, the Notre Dame herbarium has submitted over 8,000 high-resolution images of historically important type, taken from herbarium specimens in our Greene-Nieuwland Herbarium.
