Wetlands Research Program. Corps of Engineers Wetlands Delineation Manual. Appendix C. Section 1. Region A - Alaska.
Abstract
Presented is a subset of the National List of Plant Species That Occur In Wetlands of Alaska. The list was initiated by the US Fish and Wildlife Service, National Wetland Inventory (NWI). A candidate national list of more than 5000 species was developed and, using information from more than 250 taxonomic references, the NWI assigned a tentative wetland indicator status to many of the species. The indicator status categories define the estimated probability of a species occurring in wetlands. For purpose of this manual, any plant species not appearing on the plant list was assumed to be an upland species unless a strong technical rationable could be developed for adding it to the list.
