“…However, catchment characteristics probably become more important towards the top of the diagram, where the pollen evidence points to a decline in tree cover, and thus there may have been an increase in both regional aerial pollen input and the more local water-borne pollen input (Tauber, 1965;Pennington, 1979) (Vasari & Vasari, 1968) and at Machrie Moor {jfuniperus-Betula-Empetrum; Robinson, 1981). On the mainland to the west and north of Arran, at Loch Cill an Aonghais and at Na Lona Min, Juniperus and Empetrum show early Flandrian presence, preceding a major rise in Betula [Peglar (in Birks, 1980);Tipping, 1986]. At these and other southwest Scottish sites (Nichols, 1967;Moar, 1969;Birks, 1972;Dickson, 1981;Boyd, 1982Boyd, , 1986Stewart et al, 1984) Salix has a consistent if modest presence, frequently being more abundant during this period than at any subsequent period.…”

SUMMARYA sequence of lake muds and fen peat deposits from Loch a'Mhuilinn, north Arran, contains evidence for the local vegetation history for parts of the Flandrian Interglacial. The main components of this history are as follows:Sedimentation occurred under open-water conditions during early Flandrian times. By around 5000 B.P., fen peat was accumulating, and during the 2nd millenium B.P., an unexplained reversion to open-water conditions occurred.The earliest recorded vegetation immediately predates the Corylus rise and is characterized by Betula-rich woodland with Juniperus and Salix being present in places. The Corylus rise, occurring at around 8600 B.P., marks the beginning of a period of Corylus-r'ich Betula woodland. Subsequent increases of Ulmus, Quercus, Pinus and Alnus pollen represent further forest development. Fluctuations in the composition of this mixed forest are recognized, as can a distinction between areas of Betula-Quercus, Corylus-v'ich and Alnus-rich. woodland.At around 5000 B.P., the vegetational development, previously representing broad regional changes, appears to respond to local processes. Fluctuations in the proportions of trees and Gramineae pollen may reflect vegetational disturbance, although sedimentation processes may be influencing the pollen deposition at this time. This period is followed by apparently greater woodland stability, with minor indications of human activity. By around 4000 B.P., early stages of Calluna-rich heath are apparent. The development of the heath vegetation is not recorded, but by the 2nd millenium B.P., Calluna heath and grassland appear to be well established in north Arran.The history of Sorbus spp. is examined in as much detail as the fossil evidence allows. By around 6500 B.P., Sorbus aucuparia L. is present in the area, and by around 5400 B.P., evidence for non-aucuparia Sorbus species is present. This evidence may represent the former presence of 5. rupicola (Syme) Hedl. and/or one or both of the two endemic species S. arranensis Hedl. and 5. pseudofennica E. F. Warb.

ISSN (1267-81 79 R c~c t v r~l l k c c m b c r l Y 8 7 R t v w c i 8 April 1Y88ABSTRACT: Recent publications have presented palynological data from the early postglacial period in the British Isles, which have been interpreted as reflecting sequential glacial retreat following the Loch Lomond Stadial. The methodologies and results o i these studies were examined and were concluded to be insufficient to demonstrate g l x i a l retreat. A more cdutious methodology was adopted and tested at several pollen sites in the Awe valley, Scotland. The results diftered from previous studies in not demonstrating the sequence of pdlynological changes predicted from the hypothesis. These results need to be replicated at other localities, however, before the deglacial chronology hypothesis can be dismissed. Proposals to test the hypothesis further are suggested.
