Project BudBurst

Project BudBurst

is run by the

National Ecological Observatory Network, Inc




Project BudBurst engages people from across the United States in the collection of important climate change data based on the timing of leafing and flowering of trees and flowers. Project BudBurst participants take careful observations of the phenological events such as the first leafing, first flower, and first fruit ripening for a variety of plant species including trees, shrubs, flowers, grasses, weeds and ornamentals. Project BudBurst is particularly interested in observations of native plant species. The citizen science observations are reported online to a national database. As a result valuable environmental and climate change information is being collected in a consistent way across the country. Scientists can use this data to learn about the responses of individual plant species to climatic variation locally, regionally, and nationally, and to detect longer-term impacts of climate change by comparing with historical data.
