Estimated seasonal activities of fibrous, dyeing, and food plants based on Holocene data and LGM-equivalent reconstructions.
Upper: Overlapping ranges of harvesting and production periods for the three plant categories occurring between June and October. Lower: Comparison of modern (May–November) and estimated LGM-equivalent (early June–late October) active seasons, calculated using a −7 °C temperature offset for Shanxi (shaded areas).
