Welcome to Urban Tree Phenology!

Urban Tree Phenology (UTP), a special project of Project BudBurst, is designed to engage professional urban foresters and the public in observations of the phenological events of trees in our nations’ urban areas in order to raise awareness of climate change and urban heat island research. Participation in UTP is designed to be simple and straightforward. All the information you need to participate can be found on this portal page as well as additional background information about phenology and climate change.
