Mangrove Science Network
Science Center Objects
The Mangrove Science Network is a collaboration of USGS scientists focused on working with natural resource managers to develop and conduct research whose findings will support and evaluate decisions made in mangrove management and restoration.
USGS research on mangrove ecosystem biology includes mangrove regeneration, tree growth, sedimentation, and early seedling development. We are also interested in learning about how mangrove vegetation responds to and influences environmental stressors along the coast such as sea level rise and its role in attenuating storm impacts.

Date published: August 1, 2017Mapping Mangrove Condition
Mangroves have decreased worldwide due to human development, climate change and other forces. In southwest Florida, tremendous growth and development pressure has resulted in appreciable losses in mangrove wetlands.

Date published: May 11, 2016Status: ActiveRate and Process of Mangrove Forest Expansion on Carbon Relations in Coastal Louisiana
Field observations over recent decades have confirmed mangrove expansion landward in tropical zones and poleward in temperate saltmarsh settings around the northern Gulf of Mexico.

Date published: April 18, 2016Mangroves vs. Salt Marshes: Mangrove Forest Range Expansion at the Expense of Salt Marshes
Winter climate change has the potential to have a large impact on coastal wetlands in the southeastern United States.

Date published: April 17, 2016Mangrove Migration Network
At the poleward marsh-mangrove ecotone, mangrove abundance and coverage is winter temperature-sensitive in that it oscillates in response to the frequency, duration, and/or intensity of extreme winter temperatures. Future winter climate change is expected to facilitate poleward mangrove range expansion at the expense of salt marshes in Texas, Louisiana, and parts of Florida.

Date published: April 17, 2016Status: ActiveMacroclimatic Controls of Coastal Wetland Ecosystem Structure and Function
At the global-scale, macroclimatic drivers govern ecosystem structure and function in tidal saline wetlands (e.g., salt marshes, mangrove forests, salt flats). However, global reviews and models for these ecosystems typically do not directly include climatic drivers. The objective of this research is to examine and forecast the effects of macroclimatic drivers on wetland ecosystem structure...

Date published: April 16, 2016Status: ActiveClimate Change Effects on Coastal Marsh Foundation Species
Mangrove forests have migrated inland over the past few decades at many locations along the northern Gulf of Mexico coast. This expansion has been attributed to factors associated with climate change, such as increased salinity resulting from sea-level rise and longer intervals between winter freezes, which can kill cold-intolerant mangrove species.

Date published: April 15, 2016Status: ActiveEcosystem Development After Wetland Restoration and Creation
Wetland restoration and creation efforts are increasingly proposed as means to compensate for wetland losses. To address the need for evaluating the development of ecosystem structure and function in restored and created wetlands, USGS compared created tidal wetlands sites to natural mangrove wetlands in Tampa Bay, Florida.

Date published: April 8, 2016Status: ActiveEvaluating Structural and Surface Elevation Recovery of Restored Mangroves
Hydrologic restoration is one of several approaches to rehabilitate mangroves on a large-scale. USGS evaluates how solely restoring tidal hydrologic flows affect the recovery of mangroves in Florida.

Date published: April 8, 2016Status: ActiveDynamics and Fluxes of Nutrients along Environmental Gradients in the Florida Everglades, USA
USGS research in the Florida Everglades will provide information on how environmental conditions and disturbances impact carbon storage in mangrove systems.

Date published: April 7, 2016Status: ActivePlant Community Dynamics in a Mangrove-to-Marsh Transition Zone
Mangroves will compete with salt marsh plants in transitional areas, and recent studies have documented the expansion of mangroves into marsh habitats. To better understand the plant community dynamics in this transition zone, USGS scientists are tracking vegeation changes over time in south Florida.

Date published: January 25, 2017Changes in Rainfall, Temperature Expected to Transform Coastal Wetlands This Century
Changes in rainfall and temperature are predicted to transform wetlands in the Gulf of Mexico and around the world within the century, a new study from the USGS and the University of Texas Rio Grande Valley concludes.

Date published: October 3, 2016Rising Sea Levels, Coastal Development’s Effect on Gulf Coast Wetlands
As coastal development along the Gulf Coast continues to expand, tidal saline wetlands could have difficulty adjusting to rising sea levels.

Date published: August 11, 2016Ecosystems in the Southeastern U.S. Are Vulnerable to Climate Change
“From the mountains to the coast, the southeastern U.S. contains ecosystems that harbor incredible biodiversity. Many of those ecosystems are already highly at risk from urbanization and other human land-use change. Identifying the ecosystems at risk from climate change will help inform conservation and management to ensure we don’t lose that biodiversity.” (Jennifer Constanza, report author)
