The mission of the Arctic Geobotany Center is to:

• Explore and understand Arctic geobotanical relationships and dynamics at local to global scales;
• Investigate Arctic land-use and conservation issues through interdisciplinary collaboration;
• Educate and train students in Arctic vegetation field skills and analysis;
• Disseminate information about our research to educators, students, scientists and the general public.
