Utilizing herbarium specimens to assist with the listing of rare plants

open access: yesFrontiers in Conservation Science, 2023
Funding for rare plant conservation is limited. In addition, many aspects of the biology and ecology of rare plants are unknown. Therefore, low-cost data generation approaches to fill these gaps should be pursued. Herbarium specimens can be used as a low-
