New Jersey Audubon’s BioBlitz 2023

Nature is Waiting Outside Your Door: Go Explore, Collect Data and Participate in Our Third Annual Statewide BioBlitz!

April 24th to 29th

Participate in a community science extravaganza no matter where you are in the state of New Jersey. Photograph plants and animals in your neighborhood using the free iNaturalist app (info below). Interact with New Jersey Audubon staff through daily challenges, friendly competition and learning opportunities.

New Jersey Audubon’s BioBlitz 2023 encourages you to get outdoors where and when you can during the week.

iNaturalist is a crowd-sourced online application, so if you don’t know what the plant or animal is, no worries, someone else will! Just take a photo, upload it to the site and join hundreds of people learning together about all the amazing plants and animals there are in New Jersey.

Thank You to our Education Partner for Their Continued Support
