Greener Jc

Supporting a more sustainable future in Jersey City


In 2019, Greener JC launched Jersey City’s first ever BioBlitz.  A BioBlitz is a communal event where community scientists record as many species of plant and animal life as possible in a designated place and time.  Community scientists are any members of the community who want to engage with the biodiversity around them, observe and learn more.

In 2020, Greener JC will continue to host BioBlitz events in Jersey City. The first BioBlitz of the year will take place following the Liberty State Park Protection Act Rally on January 11th. The BioBlitz will begin at approximately 12pm at Caven Point Natural Area in Liberty State Park. Please join us to document the biodiversity in this urban nature sanctuary!

More BioBlitz dates are to come, so please check back in the future for more information. 

How Can You contribute to the JC Bioblitz project?

The BioBlitz 2020 project is live and active in iNaturalist. To  contribute to the project, please follow the instructions below. By the end of the year we hope to reach 500 individual observations and at least 150 species documented. Greener JC will host a City-wide BioBlitz annually, so if you or your group is interested in partnering in this initiative please reach out!


Greener JC organized the BioBlitz to allow community members to collect biodiversity data in two ways. We organized a single-day event on May 4th where multiple groups of community scientists joined members of the Greener JC team to document the natural life in the City, and we created an ongoing project in iNaturalist encouraging community members to continue adding  observations before and after our main May 4th event. The project has surpassed our expectations and we look forward to continuing to identify the  many species inhabiting Jersey City.  

2019: What did we find on the Bioblitz?


On May 4th, Greener JC partnered with the Canco Park Conservancy, Saint Peter’s University, the Friends of Van Vorst Park, and the Friends of Arlington Park to explore four of the city’s local parks.  In total, 20 community scientists joined the  Greener JC board to document 107 species across Jersey City.  Even in the rain,  the community scientists had a great time searching for and identifying the plants and animals who, like themselves,  call our city home.  Some of the exciting finds included a Great Egret, Belted Kingfisher, Wild Bergamot, Gadwalls, Coneflower, and a Greater Yellowlegs.

The project has remained open since May 4th with regular contributions by members of the community.  Newer observations have included a Scarlet Tanager,  American Goldfinches, a Polyphemus moth, and groundhogs.  Since the project’s launch on April 8th to June 22nd, a total of 122 species have been identified in Jersey City.
