Landscape Genomics: Genetic Tools to Inform Seed Source Decisions

Nicholas Wheeler, Molecular Tree Breeding Services, Centralia, WA

Assisted migration offers a means to maintain forest productivity and ecological function by expediting species movements. Identifying which seed sources to move to optimize goals will not be trivial task. With respect to reforestation, decisions regarding seed source have typically relied on natural seeding in, seed zone collections, or in special cases, information gleamed from common garden or provenance trials. Neither of the first two methods is guaranteed to produce a standing crop adapted to the future environment. Good provenance trials can significantly improve those chances, but offer a number of fiscal and logistical hurdles. Genomic studies, conducted at the landscape level, may potentially offer a suite of complementary, precision tools for guiding seed source selection assisted migration or other reforestation needs. This talk outlines the scientific basis of landscape genomics, reviews results of early studies in the field and discusses potential applications.
