Acting Locally to Understand Global Change

As a center for plant science, the Arnold Arboretum contributes to the study of our changing planet. At Weld Hill, state-of-the-art laboratories and tools enable researchers to investigate how plants will respond to changes like higher concentrations of carbon in the atmosphere. An ongoing project with Boston University collects data on nitrogen and other atmospheric pollutants in our urban environment, a first in the United States. Arboretum collections have contributed to the work of scientists like Richard Primack, who investigated historical changes in plant life cycles with herbarium specimens and archival photographs. The Arboretum is among an international network of gardens where leaf emergence, color change, and fruit ripening are tracked to enable global comparisons, while our Tree Spotter volunteers collect data seasonal change to share with researchers at the Arboretum and around the globe.
