An interactive key for winter identification of trees and shrubs in interior Alaska.

Despite the diversity of plant species found in Alaska and neighboring regions, the shortness of the growing season at the high latitudes presents a challenge for species identification outside of that period, sometimes upwards of half the year. We aim to combat this and promote community engagement by providing a new and freely available interactive online key as a resource for the winter identification of trees and shrubs of interior Alaska. The key includes both multiple-character entry and dichotomous identification pathways, with high-quality images of specific details to aid character coding for the expert and untrained user alike. These images will inform coding of non-foliar characters including leaf scar topography and vascularization, and leaf and floral bud scale arrangement and ornamentation. Observations from the iNaturalist platform will inform maps of species distributions and fill current sampling gaps across the region, as well as provide images for each species in situ. We chose 60 interior species from Viereck and Little's key to roughly 130 woody species across the state, with updated taxon concepts to parallel the current Flora of Alaska project underway at the University of Alaska.
