The 2023 St. Johns River Report, developed by researchers from UNF and other institutions, offers some signs progress for the health of the river, along with growing concerns. The analysis of the Lower St. Johns River Basin is funded by the City of Jacksonville. UNF researchers include Christopher Baynard, Dale Casamatta, Scott Jones, Adam Rosenblatt, Brian Zoellner, and Charles Closmann.
The team found that the river’s tributaries continue to be badly polluted, and wetlands continue to be lost due to development. Salinity has increased, and the water column is contaminated by pharmaceuticals such as acetaminophen and hydrocodone. On the upside, most fish and invertebrates are not in danger of overfishing, and protected species are faring well.
