DescriptionThis study used dated and measured tree-ring data to examine relationships between radial growth, topographic aspect, and precipitation for four hardwood species, yellow-poplar (Liriodendron tulipifera L.), northern red oak (
L.), chestnut oak (Quercus prinus L.), and red maple (Acer rubum L.), growing on contrasting aspects in north-central West Virginia. The main objectives of the study were to determine variation in growth between northeast and southwest aspects, examine changes in annual growth related to changes in precipitation and Palmer drought severity index (PDSI), and test for the existence of an interaction between species' growth response to drought and topographic aspect.
