Dendrochronologically dated pine buildings from Scotland: the SCOT2K native pine dendrochronology project

The SCOT2K project has extended native pine tree-ring chronology coverage for Scotland to enable reconstruction of past climate and for cultural heritage dating benefits. Using living trees from multiple locations in the Highlands and sub-fossil material from lochs, a network of five regional chronologies has been produced. The project has developed the application of Blue Intensity (BI), a proxy measure for maximum latewood density, which is faster and less costly to obtain than traditional densitometry measurements. The use of both ring-width and BI has been demonstrated to greatly assist historical dendro-dating of pine. This paper presents the dating results for the twenty Scottish pine buildings or sites dendro-dated through the SCOT2K project. They range from the fifteenth to the nineteenth centuries, and from high-status castles to modest cruck cottages. They are mostly located in the Highlands where Scots pine occurs naturally, although an early example of long-distance transport is also identified.
