Everglades

The Sparrow Helper tool allows for the evaluation of water management scenarios by generating, plotting, and mapping hydrologic metrics across a range of time scales to predict impacts of proposed water depth changes to sparrow subpopulations.

WADEM (Wader Distribution Evaluation Modeling) is a JEM model that estimates species-specific habitat suitability across the landscape for Great Egret ( Ardea alba ), White Ibis ( Eudocimus albus ), and Wood Stork ( Mycteria americana ).

Marl prairie is the most diverse freshwater vegetation community in the Greater Everglades and provides the only suitable habitat for the federally endangered Cape Sable seaside sparrow (CSSS; Ammodramus maritimus mirabilis ).

EverSnail, developed in collaboration with the University of West Florida, is an age- and size-structured spatially-explicit landscape model of native apple snails ( Pomacea paludosa ).

Because the American alligator ( Alligator mississippiensis ) is a keystone species of the Everglades ecosystem, managers need a way to quantitatively assess the effects of alternative restoration scenarios on alligators.

Critical information predicting condition changes in manatee habitat resulting from the alteration of freshwater flows to estuaries is needed to develop the PSRP Detailed Design and PSRP Operations Plan components and complete consultation under the Endangered Species Act.

Turbid water conditions make the delineation and characterization of benthic habitats difficult by traditional in situ and remote sensing methods. Consequently, only a small fraction of this valuable resource has been mapped or characterized.

Detecting invasive species at low densities or prior to population establishment is critical for successful control and eradication. For example, Burmese pythons occupy thousands of square kilometers of mostly inaccessible habitats.

The interior marshes of the Ten Thousand Islands National Wildlife Refuge (TTINWR) are currently negatively impacted by sea level rise through saltwater intrusion from the south which furthers mangrove encroachment into the freshwater marsh.

The Picayune Strand Restoration Project (PSRP) is in the process of restoring pre-drainage hydrology to the southwest portion of the Greater Everglades ecosystem.

The decline of mammal populations in Everglades National Park (ENP) over the last 20 years is likely to influence the ecology of the Everglades system and the likelihood of successful Everglades restoration.

The Joint Ecosystem Modeling team is developing and applying ecological models and other decision support tools for Greater Everglades restoration project planning.
