Archaeobotanical remains from the mid-first millennium AD site of Kaerdong in western Tibet

In this study, we present the preliminary result of archaeobotanical investigation at Kaerdong in western Tibet. The result shows that agropastoralism with combined strategies of foraging, hunting and fishing was in practice at the location between approximately 455 and 700 cal. AD. Our results also show that herding animals grazed at meadows above 4300 m above sea level (masl), and dung was used as fuel. The presence of a rice grain together with spikelet bases indicates that rice was a component of food resources possibly as a result of a trade and exchange system. In addition, tatary buckwheat grains were also recovered at the site.
