Project Budburst

A nationwide initiative by the National Ecological Observatory Network (NEON), The Chicago Botanical Garden, and others, Project Budburst allows citizen scientists (e.g., students, naturalists, gardeners) to enter observations of the timing of flowers and foliage into an online database to help create a national picture of the effects of our warming climate on plants. The project operates year-round so early and late-blooming species around the country can be monitored throughout their lifecycles. UM professors Carol Brewer and Paul Alaback are collaborators on the project; MNPS member Paul is the project's lead scientist nationally. Project Budburst is looking for Native Plant Society members and others to volunteer in monitoring when plants come out in the spring. This involves selecting one or more plants near your house-in a park or somewhere you walk regularly--then noting the day leaves and flowers first appear and leaves first change color in the fall. Observations on Mt. Sentinel would be particularly valuable. Last year over 4,000 volunteers participated nationwide! Budburst is particularly interested in observations of widely distributed plants such as chokecherry, serviceberry, red osier dogwood, garden lilacs and others. You can register to collect data at or contact Paul Alaback (; phone: 970-227-4745
