Data from provenance testing in forestry research conducted in the 1950s-1980s provide a unique opportunity to understand climate adaptation in forest trees and model populations’ responses to climate change. Even though much work has been done in conifers, studies on deciduous tree species adaptation to climate, particularly species of the Northeastern forests, are scarce. By recovering and re-analyzing data from these tests, we can start filling in this gap. Dr. Leites will present results for five deciduous species and one conifer: Acer rubrum (red maple), Betula alleghaniensis (yellow birch), Juglans nigra (black walnut), Prunus serotine(black cherry), Quercus rubra (northern red oak), and Pinus strobus (eastern white pine). She will also discuss implications of these results for reforestation and conservation under a changing climate.
