The Reuben H. Fleet Science Center is excited to announce the launch of our phenology project for this growing season, and we need your help! You will be trained to make observations about the timing of flowering plants across San Diego county, the most botanically diverse county in the contiguous United States. Volunteers visit their selected plant at least twice weekly and enter data about the changes they observe. The information is used to determine whether climate change is affecting the foliage of our area. This is a great opportunity to contribute to science while doing the outdoor activities that you already enjoy! You do not need to be a botanist or know a lot about plants; we will provide you with the training you need to be able to identify the plants and their phenophase. Citizen Scientists look for possible indicators of climate change by observing shrubs, herbs, and other native plants. By comparing current trends to the historical data, scientists hope to find out if regional climate changes are influencing the diversity, distribution or flowering of local fauna. We are literally "seeing climate through the lives of plants", and if we listen, the plants (and the animal's responses to the plants) may be telling us the story of climate change. To become a volunteer data collector, follow us on facebook by searching San Diego County Phenology Project or visit Still have more questions? Email or call (619)238-1233 x808.
