Tree Spotters Citizen Science Program
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. All levels of experience are welcome.
Program Information and Training Sessions
We have concluded training sessions for 2018, and will resume trainings in early spring; please check back for new training dates.
Responsibilities and Time Commitment
- Attend one 3 hour training class;
- Visit the Arboretum two or more times a month from March through December for a one- to two-hour tree spotting session;
- Enter your observations into your Nature’s Notebook Observation Deck (an online database created and supported by the US National Phenology Network);
- Hone your skills by participating in additional workshops and educational sessions during the year;
- Provide feedback on the program by responding to occasional surveys.
Required Skills and Interests
- Ability to meet the responsibilities and time commitment above;
- Ability to work independently;
- Interest in learning more about the Arboretum’s trees and shrubs, phenology, and climate change;
- Desire to observe nature closely and willingness to report observations accurately;
- Ability to walk outdoors for at least one hour. Walking routes across the Arboretum will bring Tree Spotter volunteers past particular plants to observe 12 different species of deciduous trees native to North America and 3 different species of native shrubs.
NOTE: One of our shrubs, Viburnum cassinoides (Withe-rod), is quite easy to observe, so if you have accessibility issues and are wondering about your ability to participate, please contact us so we can tell you about your options.
