Science of Seasons - Don Edwards Refuge Phenology Project

"Phenology is nature's calendar - when cherry trees bloom, when a robin builds its nest and when leaves turn color in the fall."  - National Phenology Network

Join the nationwide effort to monitor climate change by recording data on plants.  Long-term documentations on when plants leaf, flower, and seed can give scientists and land managers the tools they need manage resources effectively.  Specific individual plants have been identified at both the Environmental Education Center in Alviso and at Refuge Headquarters in Fremont for year-round observations.  If you would like learn more about the project and become involved, go to the National Phenology Network (NPN)website.  A tremendous amount of information can be found on this site along with instructions on how to upload your findings after creating an account.  You may also see the data collected by citizens such as yourself around the country!

To help monitor the plants specifically at the Don Edwards Refuge, trainings are held on a regular basis.  See our Activity Calendar for dates and time.  If you feel you are ready to begin, see the instructions below on how to get started!
