Callie Oldfield presented a poster at a plant science seminar at the University of Georgia this month based on data from the lab's long-term chestnut oak demography study on the Domain. Callie and her sister Sarah (Sewanee C'18) developed a matrix model that uses size class transition probabilities to predict change in size structure in a chestnut oak stand over a 100 year period. The model is parameterized by 15 years of field data in which all chestnut oak individuals in a 1 hectare plot that were greater than 0.5 m in height were tracked for survivorship and change in size.
