Jackie Raiford, Montgomery Parks Naturalist, will show how easy it is to participate, including how to download and use the iNaturalist app to submit your observations. Anyone can participate – even from your own backyard – and YOU can become a community scientist! Please have your smart phone with the free iNaturalist app pre-downloaded. An invitation to join this virtual class will be emailed 1 day prior to the start time. Teens-Adults. (R)
