Margin Edges (IMAGE) Penn State Caption Dry forest margins in the western United States may be more resilient to climate change than previously thought if managed appropriately, according to Penn State researchers. The researchers studied forest regeneration at four sites that had experienced wildfires in the eastern Sierra Nevada Mountains in California. The sites sit at the forest margin, a drier area where forest meets sagebrush grassland and which may be the most vulnerable to climate change-driven forest loss.
