Laerchenbogen, Bavarian Forest, Germany - GERM061 Additional Site Information Rob Wilson Purpose of Collection: Ecology - air pollution studies Measurement type: Total ring width Location of core material: With Robert Wilson - current location: Edinburgh University This site was originally sampled along with many others in the Bavarian Forest region to develop a precipitation reconstruction for the region. The living data were extended back in time using historical tree-ring data. However, an obvious growth reduction, probably related to air pollution, meant that these data could not be used for a reconstruction. See publication for more detail.
