The University of Michigan Herbarium is home to some of the finest botanical collections in the world. The 1.7 million specimens of vascular plants, algae, bryophytes, fungi, and lichens combined with the expertise of the faculty-curators, students, and staff provide a world class facility for teaching and research in systematic biology and biodiversity studies. The organismal and genetic resource collections such as those in the Herbarium provide the best tangible record we have of life on Earth and constitute a crucial resource for use in research and education benefiting science, society, and the university. Working collaboratively within the highly regarded Department of Ecology & Evolutionary Biology, our goal is to make UM a leading center for training and research in studies of the history, the change mechanisms, and the conservation of Earth’s diverse life forms.
