The sequence of local pollen assemblage zones is dissimilar to that found at most other sites in the Grampians for there are two zones dominated by woody species, Juniperus-Empetrum and Betula-Juniperus respectively, which are separated by a Rumex-Cyperaceae zone. Total pollen concentration varies from over 30 x 10 grains per cm in the zones dominated by woody species to only 10 x 10 grains per cm in the Rumex-Cyperacecae zone implying either an increased sedimentation rate or reduced pollen productivity at this time. The occurrence of such a sequence is not considered to be due to any stratigraphical discontinuities as there is no change in sediment lithology, but is thought to represent a significant change in the local vegetation communities with the disappearance of Juniperus and Empetrum. It is suggested that the sequence is comparable to that found by Walker at Corrydon in Glenshee (1977) and may represent the Bolling-Older Dryas-Allerod chronozones. The vegetation record of the later Loch Lomond Stadial is characterised by three local pollen assemblage zones with high values for Salix, Rumex, Thalictrum and Artemisia, the latter becoming more important towards the later stages of the stadial due perhaps to a combination of increased dryness and the loss of the interstadial soil cover.
