This inventory of the vascular flora of Fort Greely in interior Alaska was conducted sporadically during summer 1996,1997,and 1998. Fort Greely covers 0.66 million acres 267,763 haand is composed of five major subdivisions1the large floodplains of Jarvis Creek, the Delta River,Delta Creek,and Little Delta River,2the surrounding lowlands associated with these rivers,3several glacial mo- raines,4two highland areas Molybdemum Ridge and Dinosaur Ridge,and 5the higher mountains of the Alaska Range up to 2000 m in elevationalong the southern edge of the base.Habitats range from very dry south-facing slopes to forest,floodplains,wetlands, and alpine tundra.About 100 sites were visited and 723 collections made,which represented 497 taxa of vascular plants from 64 families and 198 genera.A species list for the Fort Greely survey was compiled and is presented here.It is estimated that the vascular plant inventory is relatively complete.The inventory includes 21 rare species being tracked by the Alaska Natural Heritage Program and 11 species representing significant range extensions 150 km.The relationship of the Fort Greely flora to that inventoried on Fort Wainwright is discussed.
