Tree Spotters Citizen Science Program: Beyond the Basics Training


Saturday, September 7, 2019, 2:00pm to 4:30pm


Hunnewell Building

With nearly 4,000 different kinds of plants represented in the Arboretum's living collections, every day presents rich opportunities to see something new. If you enjoy learning about plants and their unique characteristics, you can contribute to science as a participant in our Tree Spotters program. This citizen science project opens a window into the Arboretum's phenology: the timing of natural events, such as the leafing out and flowering of trees in the spring and changing foliage colors in the fall. Your observations will assist Arboretum scientists in their studies of the effects of a changing climate on plants. 

Each new Tree Spotter must first attend one Basic Training class (Module 1), followed by a Beyond the Basics class (Module 2). Please register for both modules if you would like to participate in this program. 

 This Beyond the Basics class covers the phenology of northern red oak, white oak and common witch-hazel, and includes an outdoor component. Participants should be prepared to walk on the grounds for roughly one hour. For concerns about inclement weather, text or call Suzanne Mrozak at 857-321-2825.

All Tree Spotters events are free, and all levels of experience are welcome. Visit the Tree Spotters web page to learn more about the program and see training session dates for Modules 1 and 2.
