We are modeling species- and population-level growth responses to changes in climate using provenance and common garden tests data. These are experiments in spatial climate change where the climate at which the seed source has originated differs from that of the test site. When populations are tested in several sites, differences in growth responses to changes in climate can be elucidated. These models are providing crucial insights on species adaptation to climate and potential populations' responses to climate change as well as guidelines for seed transfer under an adaptive management context.
