ACCS has been tracking all non-native plants known to occur in Alaska since 2002. To qualify for listing, the species must be found escaped outside of a designated planting/gardening area and not on private lands. The designation of nativity status for plants involves a careful review of the known distribution of the species and documentation of earliest establishment in our region. We consider the context of early botanical explorers documenting the flora of Alaska by using historic floras, herbaria records, and current scientific literature to inform our listing decisions and document the first presence in our region. Here we list the non-native plant species known to or likely to occur in our region. In collaboration with biologists, land managers, and weed scientists across the state, ACCS has developed an invasive plant ranking system that helps evaluate the potential invasiveness and impacts of non-native plants to natural areas in Alaska (Carlson et al. 2008). Most species have biographies and an invasiveness rank.
