Indiana Phenology Citizen Scientist Observer Program

Hoosiers of all ages in recording the timing of leafing, flowering and fruiting of plants (aka phenology). We study the trends in the timing of these seasonal changes of plants and animals in Indiana to understand the impacts of climate change in Indiana. I’m writing to invite Purdue Extension Master Gardeners to join us in our efforts by observing and recording phenology in their gardens through the Indiana Backyard Observers program.  I think backyard observing would be an excellent volunteer opportunity for Extension Master Gardener volunteers! For people who already love to observe the plants in their yards, recording their observations for science is an easy and fun next step.

All volunteer observers are strongly encouraged to go through training to best understand the observational best practices that make the citizen science effort most valuable to users of the data.  Two duplicate training webinars will be held on May 7, 2020.
