As a center for plant science, the Arnold Arboretum contributes valuable data and scholarship to the study of Earth’s changing climate. At Weld Hill, the laboratory of Harvard Professor Elizabeth Wolkovich studies how spring has shifted earlier in most parts of the world, including its effects on the wine industry. Arboretum records 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. Volunteer Tree Spotters collect data on some species as a citizen science initiative.
