The eleventh installment of the Eastern Seed Zone Forum's online lecture and discussion series aimed at providing both information about the creation of seed zones in general and a forum in which professionals, experts, and interested parties discuss the possibility of drafting seed zone guidelines for the eastern United States. In this webinar, Dr. Leites will discuss efforts to recover and re-analyze provenance tests data for northeastern forest tree species and illustrate how new analyses can inform seed movement under a changed climate.
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.
