The Scottish Pine Project: Trees, Lakes and Climate

Presented by Dr. Rob WILSON on 14 May 2013 from 16:10 to 16:30
Type: Oral Presentation
Track: Climate of recent millennia


The living pine network across the Scottish Highlands is now numbered at ~50 sites with almost complete representation of all remnant semi-natural pine woodlands. Due to human impact in the 18th/19th centuries most of the sites are only well replicated back for ~200-250 years. Extension of these chronologies is only possible using both historical and/or sub-fossil material. Sub-fossil samples have been extracted from several lakes in the Northern Cairngorms and radiocarbon dating identifies material from multiple periods over the last 8000 years. We have also collected sediment cores from two lakes and undertaken a range of palynological and paleolimnological analyses. Results of this multi-proxy comparison will be presented. Despite tree-ring calibration explaining >50% of the summer temperature variance, problems exist. Detrending biases related to the human disturbance and temporally unstable response in ring-width data first need to be overcome before any new dendroclimatic reconstruction is published for this region.
