Mission of the Arctic Geobotany Center
- 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.
Recent AGC Publications
CAFF Proceedings Volume September 2019: Arctic Vegetation Archive and Arctic Vegetation Classification: Proceedings and abstracts from two workshops 2017 and 2019. Read the report
Likely impacts of proposed 3D-seismic surveys to the terrain, permafrost, hydrology, and vegetation in the 1002 Area, Arctic National Wildlife Refuge, Alaska. A white paper by Alaskan scientists detailing 10 issues regarding conditions in 1002 Area and the likely cumulative effects of 3D-seismic surveys. Read the report
The Raster Circumpolar Arctic Vegetation Map (Raster CAVM) maps 16 vegetation types, glaciers, saline water, and freshwater at 1-km resolution. It builds on the strengths of the original CAVM, using the same legend, extent and projection, while providing a finer spatial resolution, raster format, and improved mapping of Arctic vegetation.
