Cereal pollen grains in pre-elm decline deposits: Implications for the earliest agriculture in Britain and Ireland

Evidence of cereal type pollen grains in the pre-elm decline sections of pollen profiles is demonstrated from five sites in Ireland and three in Britain. Technical and archaeological considerations are also discussed. It is concluded that cereal cultivation in the British Isles occurred before the traditional beginnings of arable activity as denoted by the elm decline, and that the palynological data should be seen to underline caution in referring pre-elm decline pollen changes to Mesolithic disturbance.
