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