As Patricia K. Holmgren Director of the William and Lynda Steere Herbarium, Barbara Thiers was responsible for overseeing the Garden’s 7.9 million collections of algae, bryophytes, fungi and vascular plants and the approximately 30 staff members who manage these collections. The Steere Herbarium is the largest in the Western Hemisphere, and third largest in the world. It is the world’s most heavily used herbaria in terms of the number of specimens loaned or imaged on demand, and the number of visitors to the Herbarium.
Barbara has been particularly interested in the application of information technology to herbarium management, and to increasing access to specimen-based data for the scientific community. These interests have led to the development of The C. V. Steere Virtual Herbarium, which contains a searchable database of digitized herbarium specimens (4.5 million so far, with 400,000 added each year). Barbara is also the Editor of Index Herbariorum, the guide to the world’s approximately 3300 herbaria and 12,000 associated staff. She has been involved in the development national initiatives to digitize the natural history collections in the U.S. as an author of the Network Integrated Biocollections Alliance plan, issued in 2010; as member of the Advisory Committee of the Biodiversity Collections Network; and the lead author of the Extended Specimen Network plan. Barbara is also a co-author of the recent National Academies of Sciences and Engineering report on biological collections.
Barbara Thiers is President of the American Society of Plant Taxonomists (2020-2021), Past President of Society for the Preservation of Natural History Collections (2020-2022), a member of the Board of the Natural Science Collections Alliance, and member of the External Advisory Board of iDigBio, the national collections digitization hub.
The subject of her research is the Hepaticae. In particular, she is interested in the systematics and morphology of the largest family of Hepaticae, the Lejeuneaceae. This family is primarily tropical in distribution, and its members can be found growing, often profusely, on the bark and sometimes on living leaves of trees in tropical rainforests. Her studies of these small but beautiful plants have taken her to Australia, Colombia, Dominican Republic, Ecuador, French Guiana, Papua New Guinea, Puerto Rico and Venezuela.
Barbara has a strong interest in the history of botanical collecting and the history of the herbarium; this interest has culminated in my book, Herbaria: The Quest to Preserve and Classify the World’s Plants (Timber Press, 2020).
