Charred Plant Remains Identification
Far Western employs a team of archaeobotanists who specialize in the recovery and identification of charred plant remains from archaeological sites. Archaeobotanical findings are integrated into Far Western excavation reports to address project-specific and regional research issues. In conjunction with remains of terrestrial animals and birds, fish, and shellfish, plant remains can help investigate prehistoric and historic-era use of food resources, changes in use of native foods across time and space, and reconstructing past environments and their changing patterns as landscapes evolved. Far Western also studies variability in fuel use through wood charcoal identification, working with Paleoscapes Archaeobotanical Services Team of Bailey, Colorado.
Far Western’s archaeobotany lab features flotation equipment and personnel capable of processing hundreds of archaeological sediment samples. Archaeological plant remains are identified with the aid of a reference collection of more than 500 seed, fruit, root, and wood samples from California and Nevada. Far Western has three binocular microscopes with capacity ranging from 7–70 magnifications, including digital image capture capability, and a digital scale with resolution to 0.1 milligram for weighing wood charcoal, nutshell, and berry pit fragments. Archaeobotanical data are entered into a relational database with quantitative and qualitative data on more than 2,400 flotation samples from cismontane California and hundreds of samples from the Great Basin and Mojave Desert.
Far Western’s archaeobotanists have worked with plant remains in California and Nevada since 1981. Archaeobotany lab director Dr. Eric Wohlgemuth has more than 30 years of experience in the field, and has written more than 100 reports on the subject, including several peer-reviewed publications on California plant remains. His research interests in California archaeobotany involve the evolution of and geographical variation in hunter-gatherer intensive plant use in California. Assistant Archaeobotanist Angela Arpaia, BA, also has many years of experience in identifying plant remains from California and Nevada, and she has presented scholarly papers on ancient California plant use.
