SUMMARYHolocene and partial Latcglacia\ age ptrtentage and CDD cent rat ion pollen diagrams are presented of two profiles from the Inner Hebridean site of Loch a'Bhogaidh, Islay. The Lateglacial deposits nriay extend back to Lateglacial Interstadial times and a relati\e lack oi Juniperus communis pollen is noted. The early Holocene deposits contain abundant Betula and Corylus avellana-iype pollen, followed by substantial amounts of pollen from other arboreal taxa, namely Pinus sylvestris, Ulmus., Quercus, Alnus glutinusa and Salix. There is pollen, charcoal and sedimentary evidence for possible Mesolithic age en\ironmenial impacts, and a hunter-gatherer presence on Islay may date from the lOth millennium BP. Major woodland clearance dates from middle Bronze Age times onwards (c. 3610 BP) and involved a mixed farming regime. The later Holocene records show that soil deterioration was occurring as heath and acid grassland taxa become prominent. These events may have resulted from land use pressures or climate change.
