Over a 24-hour period between 5 p.m. on Friday, June 17, and 5 p.m on Saturday, June 18, Great Swamp Watershed Association (GSWA), the U.S. Fish & Wildlife Service (USFWS) and the Friends of Great Swamp (FGS) led more than 150 scientists, volunteers and participants in a concerted effort to find and identify as many different plant and animal species as they could within the confines of northern New Jersey’s 7,768-acre Great Swamp National Wildlife Refuge. As data continues to roll in from the event, BioBlitz 2011—the third of its kind to be held in the Great Swamp watershed since 2007—seems poised to exceed all the scientific and educational benchmarks established by past BioBlitz gatherings.
