Help us document the biodiversity at Willow Lake Farm using iNaturalist. City Nature Challenge is a global celebration of biodiversity in and around urban areas. Over 1 million observations and 45,000+ species were identified by 52,000 participants in 2021.  We will work to document as many trees, plants, animals and insects we can find.


  • Participants should bring an electronic device with iNaturalist downloaded or a camera
  • Dress for the weather
  • Be prepared for muddy and wet trails
  • For those unfamilar with iNaturalist, see this video on our YouTube channel:


We are happy to offer our programs at no cost to participants, but if you are able, a $10 suggested donation would be greatly appreciated. Wissahickon Trails is a local, community-supported nonprofit. Our budget depends entirely on the generosity of our supporters—individuals, foundations, and corporations.  Donate online today.
