Dendrochronology of Subfossil Pine in the North of Ireland

1 Two subfossil pine chronologies relating to the third and sixth millennia BC have been completed from sites in the north of Ireland. 2 The chronologies are replicated by trees from several sites and the more recent chronology is dated to 3451-2569 BC by cross dating with the long north of Ireland oak chronology. 3 The bog pines show higher autocorrelation and lower levels of cross-dating than commonly found in bog oaks. 4 Dendrochronological dating of bog pines may be used to throw light on the timing and interpretation of the pine decline in Britain and Ireland.
