North American Floristic Provinces (modified from CAVM Team 2003 and Elven et al. 2011)
Key: 
Alaska/Yukon 
Western Canadian Arctic 
Eastern Canadian Arctic 
Ellesmere
Floristic regions for the Arctic Flora of Canada and Alaska are based on floristic regions defined in the Panarctic Flora (Elven et al. 2011) and the Circumpolar Arctic Vegetation map (CAVM; described in Walker et al. 2005 and available at http://www.arcticatlas.org/maps/catalog/index), which was based on an earlier version of PAF. The floristic regions here differ from PAF and CAVM in name and/or boundaries.
