Welcome to Project BudBurst!


People watching plants

Contributing to research

Join Project BudBurst


We are a network of people across the United States who monitor plants as the seasons change. We are a national field campaign designed to engage the public in the collection of important ecological data based on the timing of leafing, flowering, and fruiting of plants (plant phenophases). Project BudBurst participants make careful observations of these plant phenophases. The data are being collected in a consistent manner across the country so that scientists can use the data to learn more about the responsiveness of individual plant species to changes in climate locally, regionally, and nationally. Thousands of people from all 50 states have participated. Project BudBurst began in 2007 in response to requests from people like you who wanted to make a meaningful contribution to understanding changes in our environment.

We make our data freely available to all in several formats on the View Results page. The data is currently being used by scientists and educators in the Project BudBurst network. The bigger question is what can YOU do with the data? We would like to know what data you think would be useful and how you would like to use it.

Why and How to participate

Project BudBurst is open to people of all ages and abilities. To better understand the stories that plants tell, we need people from all over the United States representing diverse plant communities. Since 2007, participants have included school groups, backyard naturalists, gardeners, seniors in retirement communities, scout groups, college professors and their students, hikers, professional botanists and ecologists, visitors to botanic gardens, visitors to Wildlife Refuges and National Parks, and others interested in contributing to a better understanding of plants and climate change.

The participation is fully free. Everything you need to participate is on our website and freely downloadable. We will not try to sell you anything or ask you to enroll in costly training classes. In fact, it is our intent to provide you with materials that will make it easy for you to join the Project BudBurst community and share your observations with others.
