Vegetation phenology is the study of the timing of recurring biological events in plants, such as leaf emergence, flowering, and fruit maturation. This area of research focuses on understanding how climate change and environmental factors influence the timing of these events, as well as the implications for ecosystems, agriculture, and biodiversity. Phenological observations are often used to track long-term changes in plant behavior and study the impact of climate change on plant communities. By monitoring vegetation phenology, researchers can better understand the responses of plants to changing environmental conditions and predict future trends in plant growth and development.
