TREE-RING STUDIES IN THE SOMERSET LEVELS: THE MEARE HEATH TRACK 1984-85.

Author(s): R A Morgan

This report describes the examination of almost 200 oak tree-ring samples from an important series of transverse and longitudinal planks and stakes, as well as a small study of roundwood of various species. The value of the wood lay in the fact that it was still in situ, whereas the majority of previous samples were found after disturbance by peat-cutting or excavation long ago. Thus conclusions could be reached about the relationships of tree-ring patterns and functions. The usually thick and narrow planks were split in a variety of ways, from trees probably under 500mm in diameter and 150 years old. 101 tree-ring curves were cross-matched, bringing the total to 241; the existing data was also reworked to suggest the presence of a number of characteristic growth patterns, perhaps related to areas of woodland. They also indicated some severe disturbance to tree growth in the decades before the track was built. The presence of sapwood on at least 10 timbers did not resolve the question of felling date for the trees, which is now quoted as arbitrary years 150-155. Absolute dating has not yet proved possible but Hillam'swork has revealed a correlation with another Somerset chronology from the Tinney's tracks.
