This project will be in the field of dendrochronology, which is the science of dating annual growth of tree-rings and determining the biotic and abiotic variables that control growth. Trees record anything from the environment either from direct or indirect means. This research project will focus on analyzing the relationship between annual tree growth and climate of three Quercus alba (White Oak) old growth sites across the ridge and valley region of Virginia. The three sites will be statistically tested for similar climactic signals from previous May to current October. The data will go through KNMI climate explorer for correlations in temperature, precipitation, PDSI (Palmer Drought Severity Index), and other climate options. The expected results from this analysis will be compared with Speer et al. (2009) and Goldblum (2010) to correlation coefficients across the Eastern United States. A project of this caliber gives wildlife and city managers the understanding to what factors control tree growth in the past. This can help us predict what will happen in the future as climate change continues.
