Climate Castaways

Season 4 | Episode 2 | March 2, 2023

Trees have had to migrate for millennia due to changes in climate. However, the pace of climate change today is far greater than historical tree migration rates, and land use changes have created new barriers to species movement. This has foresters and land managers thinking about the need for human-assisted movement of tree seed or seedlings to ensure that forests remain well-adapted to climatic conditions, a concept referred to as forest-assisted migration. In this episode of SilviCast we explore this complex issue with Dr. Carrie Pike, forest regeneration specialist with the U.S. Forest Service Eastern Region. Dr. Pike brings in-depth knowledge of forest genetics, nurseries, and reforestation to help us consider practical and strategic approaches to assisted migration.
