Habitat Modeling for the Endangered Everglades Snail Kite and Its Prey
Joint Ecosystem Modeling (JEM) provides real-time habitat suitability models for species of interest in Everglades restoration planning, including the federally endangered Everglades snail kite.
Socio-Ecological Conservation Targets for the Peninsular Florida Landscape Conservation Cooperative
Peninsular Florida has a high density of species and ecosystems of conservation concern, as well as many threats to the persistence of native species and their habitats. USGS worked closely with the Peninsular Florida Landscape Conservation Cooperative to define conservation targets to help meet conservation goals.
Sea Turtle Habitat Use at Buck Island Reef National Monument, U.S. Virgin Islands
USGS researchers tag and track endangered and threatened sea turtles to inform adaptive management strategies in marine protected areas.

Joint Ecosystem Modeling (JEM) Restoration Runs R Library Joint Ecosystem Modeling (JEM) Restoration Runs R Library
restoration_runs is a library of R-language scripts used to summarize/post-process output of Joint Ecosystem Modeling (JEM; https://jem.gov/) models used in Everglades restoration planning for projects such as the Lake Okeechobee System Operating Manual (LOSOM) and the Western Everglades Restoration Project (WERP). The scripts summarize model output and create graphs and maps for each...
Updates to the Everglades Vulnerability Analysis (EVA) vegetation module Updates to the Everglades Vulnerability Analysis (EVA) vegetation module
The Everglades Vulnerability Analysis (EVA) is a series of connected, modular Bayesian networks that predict the response of several Everglades indicators of ecosystem health to changes in hydrology, salinity, and the landscape. This release provides the code to update the vegetation module of EVA, validate the updated module, and provides the process and outputs of a sensitivity...
Satellite tracking of sea turtles using Biscayne National Park, 2009-2021 Satellite tracking of sea turtles using Biscayne National Park, 2009-2021
This dataset includes details of loggerhead and green turtles captured and satellite tagged between 2009 and 2021; the turtles presented here have tracking days within Biscayne National Park. A subset of turtles was captured within Biscayne National Park, whereas others were tracked to the study site, and tagged elsewhere. The dataset contains information related to satellite tracking (e...
KiteNest modeling scripts and output KiteNest modeling scripts and output
KiteNest is a spatially explicit model of Everglades snail kite (Rostrhamus sociabilis plumbeus) relative nest site selection that quantifies the relationships between a range of environmental factors and nest site selection specific to the southern portion of the species' range. Using hydrologic conditions such as mean 2-week water depth and water depth change rate, days since the last...
Satellite tracking data for post-nesting green turtles from Northwest Florida (2002-2020) Satellite tracking data for post-nesting green turtles from Northwest Florida (2002-2020)
This dataset includes processed satellite tracking data collected from green turtles between July 2002 and October 2020 in the Gulf of Mexico along the west coast of Florida from the Florida Keys to the Gulf Islands National Seashore. It contains model output including from the state-space model (SSM) described in Lamont et al. (2022) and centroids associated with the 50 percent and 95...
Sea level rise scenarios for the Cape Sable seaside sparrow Sea level rise scenarios for the Cape Sable seaside sparrow
The endangered Cape Sable seaside sparrow (Ammospiza maritima mirabilis; CSSS) occurs in marl prairie habitat at the southern end of the Everglades, at the southernmost part of the Florida peninsula. The locations of three of its six subpopulations are proximate to the coast, putting them at risk for inundation caused by sea level rise (SLR). The spatially explicit predictive model...

Loggerhead marine turtles (Caretta caretta) nesting at smaller sizes than expected in the Gulf of Mexico: Implications for turtle behavior, population dynamics, and conservation Loggerhead marine turtles (Caretta caretta) nesting at smaller sizes than expected in the Gulf of Mexico: Implications for turtle behavior, population dynamics, and conservation
Estimates of parameters that affect population dynamics, including the size at which individuals reproduce, are crucial for efforts aimed at understanding how imperiled species may recover from the numerous threats they face. In this study, we observed loggerhead marine turtles (Caretta caretta) nesting at three sites in the Gulf of Mexico at sizes assumed nonreproductive in this region...

Landscape-scale drivers of endangered Cape Sable Seaside Sparrow (Ammospiza maritima mirabilis) presence using an ensemble modeling approach Landscape-scale drivers of endangered Cape Sable Seaside Sparrow (Ammospiza maritima mirabilis) presence using an ensemble modeling approach
The Florida Everglades is a vast and iconic wetland ecosystem in the southern United States that has undergone dramatic changes from habitat degradation, development encroachment, and water impoundment. Starting in the past few decades, large restoration projects have been undertaken to restore the landscape, including improving conditions for threatened and imperiled taxa. One focus of

Migration corridors and threats in the Gulf of Mexico and Florida Straits for loggerhead sea turtles Migration corridors and threats in the Gulf of Mexico and Florida Straits for loggerhead sea turtles
Along migration corridors, animals can face natural and anthropogenic threats that differ from those in breeding and non-breeding residence areas. Satellite telemetry can aid in describing the timing and location of these migrations. We use this tool with switching state-space modeling and line kernel density estimates to identify migration corridors of post-nesting adult female...

Potential impacts of future urbanization and sea level rise on Florida’s natural resources Potential impacts of future urbanization and sea level rise on Florida’s natural resources
As urban development continues to encroach into natural systems, these ecosystems experience increasing degradation to their form and function. Losses in biodiversity and ecosystem function are further compounded by changing climatic conditions. The State of Florida is known for its biodiversity but has experienced declines in species populations and habitats because of urbanization and...

Coastal marsh bird habitat selection and responses to Hurricane Sandy Coastal marsh bird habitat selection and responses to Hurricane Sandy
Wetlands provide numerous ecosystem functions such as water purification, nutrient cycling, and wildlife habitat. Avian populations are indicators of wetland health, and understanding their responses to extreme events can aid in targeting restoration efforts following disturbance. Here, we assessed the habitat selection of six coastal wetland bird species (American Bittern, Black-crowned...
