Our TerraCorps member Nick Tepper took over the Mass Audubon iNaturalist account from April 26 to April 29 to participate in Boston’s City Nature Challenge: a fun-filled citizen science competition to document biodiversity around the world.
Nick submitted over 400 observations and documented over 220 species. Here are some of his favorite photos from the challenge:
