California’s Changing Climate: Translocation, Transplantation, Assisted Migration, (mq4th) (P, C)
Session Chair: Arlee Montalvo: Transplantation, translocation, and assisted migration of plant populations are often considered when restoring, recovering, and conserving plant populations, whether rare or common. The choices one makes are now further complicated by projected changes in climate and how different populations, taxa, and interacting species might be affected. The purpose of this session is to explore when there may be a need for translocation, transplantation, and assisted migration to restore, recover, and conserve plant populations, how information about projected changes in climate might alter choices, how populations may be selected and deployed in a way that reduces risk, and to identify knowledge gaps and future research needs

Session Chair: Tom Gaman. California oak woodlands have been enduring anthropogenic threats since the state was formed in 1849. These threats include urban and agricultural development and ranching, fire suppression, and a mosaic of pressures – disease, drought, invasive species, and fire—associated with and exacerbated by fire suppression and a changing climate. This session is designed to examine critical oak woodland habitats in the oak “belts,” which surround California river valleys. It will explore the science, policies, and practices necessary to conserve, stabilize, and regenerate critical oak woodlands ecosystems in the face of ever-increasing social, climatic, and ecological pressures.
