She explains, “Macrofloral analysis from archaeological excavation is an important component of the overall analysis of a site.”  Diedrich has been hired for this specialized work by such organizations as the Washington State Department of Transportation, Drayton Archaeology Research, and Rain Shadow Research, Inc., and Cultural Resource Consultants, Inc.

Diedrich’s successful academic career at UI&U resulted in articles published in both the Journal of Wetland Archaeology and Archaeology in Washington Journal.  The articles Diedrich authored in Journal of Wetland Archaeology, Volume 9, focus on the site work she completed at Sunken Village Archaeology Site on Sauvie Island, Oregon, during her application courses.  Her thesis work, "Pacific Northwest Paleobotany: Native Seeds and the Creation of a Comparative Library," was published in Archaeology in Washington Journal and describes the importance of sampling for botanical material in Pacific Northwest Archaeology, her efforts to design a seed-key, and the digital photography of native seeds as a comparative library for research.
