Daniel Ohlsen

Flora Botanist

Daniel currently maintains and updates the plant identification website VicFlora, produced by the Royal Botanic Gardens. He is also involved with various other projects, including the collection of new plant specimens for the Herbarium, providing conservation assessments for threatened species, research, environmental consulting, writing profiles for the Flora of Australia online, and the teaching of botany and related courses. Daniel’s core research interests are fern taxonomy and systematics in the Malesian and Australasian regions.
