Tree Spotters Citizen Science Program Phenology Data
Active from 2015 through 2020, the Tree Spotters Citizen Science program partnered with the National Phenology Network (NPN) to train citizen scientists to collect phenology data from 15 native tree species at the Arnold Arboretum. During the program’s six-year span, hundreds of volunteers submitted over 330,000 phenological observations to the NPN’s database. These data can be accessed using the link below, or using the NPN’s Phenology Observation Portal or Phenology Visualization Tool.
