The episodic periods of climate change between the end of the Pleistocene and the Early Holocene had significant effects on vegetation in the Levant. The three Late Epipalaeolithic phases at Tell Abu Hureyra (c. 13.1 kya cal. BP to 12.0 kya cal. BP) span the onset of the Younger Dryas when there was a reversion to cold and dry conditions from the preceding warmer/wetter Bolling-Allerod interstadial. The deterioration of the climate is argued to have caused a recession of Mediterranean woodland from the immediate environs of the site and thus the habitats of many of the edible large-seeded annual plants became less accessible. Changes in the taxonomic composition of the archaeobotanical samples from the three Late Epipalaeolithic phases were interpreted by the original analyst as reflecting diet change in response to a reduction in resource availability, with the inception of cultivation of wild cereals and large-seeded legumes to maintain yields of these high-ranked species. In this reassessment of the data we propose an alternative model and demonstrate that the changes in plant exploitation strategies at Abu Hureyra, which coincide with the onset of the Younger Dryas, can be more parsimoniously interpreted as representing a broadening of the plant diet to compensate for a loss in availability of higher-ranked species.
