The Department of Defense (DoD) is responsible for administering more than 25 million acres of federally owned land in the United States. As a land manager, the DoD must comply with the intent and directives of a number of cultural resources related statutes, regulations, and policy memoranda. Because of these statutes, regulations, and policy memoranda, the potential impacts of land-use proposals on elements of Native American people's culture have become part of the social impact assessment studies used to evaluate the social soundness of proposed projects. These statutes, regulations, and policy memoranda requiring consultation with Native American groups and preservation of traditional cultural properties require comprehensive surveys that may include ethnobotanical surveys. Ethnobotanical surveys do not exist for most installations. A preliminary ethnobotanical survey of Fort Riley, Kansas was conducted. Results of this survey are reported and the approach used defines methodology and data sources applicable to many DoD installations.
