Rikke Reese Næsborg, Ph.D. 

Only if we understand, will we care. Only if we care, will we help. Only if we help, shall all be saved – Jane Goodall

Rikke Reese Næsborg, Ph.D., is the Tucker Lichenologist at Santa Barbara Botanic Garden and curator of the Garden’s lichenarium. She is interested in investigating lichen community composition and ecology in order to identify why different lichen species are distributed differently across landscapes. Another major interest is conservation of lichens — a complicated task that is only possible by expanding knowledge of lichen distribution and ecology. Reese Næsborg earned her bachelor’s and master’s degrees at University of Southern Denmark and went on to earn a doctorate in systematic botany from Uppsala University in Sweden. She has lived in California since 2011. 

Research interests: lichenology, community composition, lichen ecology, lichen conservation
