The impact of summer temperature changes on vegetation development in Ireland during the Weichselian Lateglacial Interstadial
Abstract We analysed pollen from a sediment core from Fiddaun, a small Lateglacial lake basin in western Ireland. Results reflect the general Lateglacial vegetation development in Ireland, as reconstructed from other pollen records. The Fiddaun diagram shows a number of short‐lived regressive vegeta...

It seems that the first cold oscillation (GI‐1d) had the most distinct effect on vegetation in Ireland. In contrast, it appears that the transition from Juniperus shrubland and Empetrum heath to grassland, which is estimated at ∼13.7 ka BP, was not caused by decreasing summer temperatures, as no substantial change is observed in the climate proxies.
