Long Pine Key Campground Closed
Due to improvements to park roads and parking lots, the reopening of the Long Pine Key Campground will be delayed due to paving work. It will reopen mid-December. Those desiring to camp will be able to utilize the Flamingo Campground instead. More »
CESI Modeling Project 06-2
Manatees were first afforded federal protection in 1967, and a significant portion of Florida's population resides in the waters of Everglades National Park. Manatees remain at risk, largely due to low reproductive rates, a decline in suitable habitat, and accidental collisions with motor boats. It is important for managers to understand what impact intended Everglades restoration activities might have on this endangered species.
This CESI-funded project developed integrated, regional hydrologic models covering nearly the entire southwest coast south of Naples, providing a much needed tool for evaluating restoration effects on coastal, estuarine, and freshwater ecosystems. This data was then incorporated into an individual-based model for the purposes of evaluating how completion of restoration projects (particularly the Picayune Strand) might affect the availability of the freshwater, forage, and refugia upon which manatees depend.

Did You Know?
Soft-shell turtles may not have the protective hard covering seen on other turtles, but they make up for that with relatively greater speeds in the water. Also, their long noses are well adapted for snorkeling. These amazing animals seem perfectly built for a life in the Everglades!
