Mangrove damage along northern Gulf of Mexico from extreme freeze event on February 2021
Climate change is altering the frequency and intensity of extreme weather events. Quantifying ecosystem responses to extreme events at the landscape scale is critical for understanding and responding to climate-driven change but is constrained by limited data availability. Here, we integrated remote sensing with ground-based observations to quantify landscape-scale vegetation damage from an extrem
2021 Gulf of Mexico Mangrove Freeze Damage Data
This data set contains measurements of black mangrove (Avicennia germinans) leaf damage following the February 2021 freeze event that affected mangroves in the northern Gulf of Mexico.
Soil elevation change in mangrove forests and marshes of the Greater Everglades: a regional synthesis of surface elevation table-marker horizon (SET-MH) data
The surface elevation table (SET)-marker horizon (MH) approach (SET-MH, together) is a method for quantifying surface elevation change through measurements of surface and subsurface processes that control wetland soil elevation. This dataset combines SET-MH data from five different U.S. Geological Survey efforts to monitor surface elevation change in the coastal wetlands of the Greater Everglades
The distribution and structure of mangroves (Avicennia germinans and Rhizophora mangle) near a rapidly changing range limit in the northeastern Gulf of Mexico
In coastal wetlands, one of the most striking examples of climate change is the poleward range expansion of mangrove forests in response to warming winters. In North America, the Cedar Key region has often been considered the range limit for mangroves along the western coast of Florida (USA). However, within the past several decades, robust stands of Avicennia germinans and Rhizophora mangle have
Mangrove distribution in the southeastern United States in 2021
Global climate change is leading to large-scale shifts in species' range limits. For example, rising winter temperatures are shifting the abundance and distributions of tropical, cold sensitive plant species towards higher latitudes. Coastal wetlands provide a prime example of such shifts, with tropical mangrove forests expanding into temperate salt marshes as winter warming alleviates past geogra
Coastal wetland vegetation and elevation data characterizing a Sudden Vegetation Dieback event in San Bernard National Wildlife Refuge in 2019
Climatic extremes are becoming more frequent with climate change and have the potential to cause major ecological shifts and ecosystem collapse. Along the northern Gulf of Mexico, a coastal wetland in the San Bernard National Wildlife Refuge in Texas suffered significant and acute vegetation dieback following Hurricane Harvey in 2017. We identified plant zonal boundaries along an elevation gradien
Landscape position-based habitat modeling for the Alabama Barrier Island feasibility assessment at Dauphin Island
A barrier island habitat prediction model was used to forecast barrier island habitats (for example, beach, dune, intertidal marsh, and woody vegetation) for Dauphin Island, Alabama, based on potential island configurations associated with a variety of restoration measures and varying future conditions of storminess and sea-levels. In this study, we loosely coupled a habitat model framework with d
Increasing rates of carbon burial in southwest Florida coastal wetlands
This data set represents vertical accretion data from feldspar marker horizons in Rookery Bay National Estuarine Research Reserve and Ten Thousand Islands National Wildlife Refuge collected between 1989 and 2017 associated with the publication 'Increasing rates of carbon burial in southwest Florida coastal wetlands.'
Rapid peat development beneath maturing mangrove forests: quantifying ecosystem changes along a 25-year chronosequence of created coastal wetlands
Mangrove forests are among the world's most productive and carbon-rich ecosystems. In addition to providing important fish and wildlife habitat and supporting coastal food webs, these coastal wetlands provide many ecosystem goods and services including clean water, stable coastlines, food, recreational opportunities, and stored carbon. Despite a growing understanding of the factors controlling man
Everglades National Park sediment elevation and marker horizon data release
This data set represents the relevant study site information for the Everglades National Park LTER sediment elevation table - marker horizon study.

Local and landscape-scale data describing patterns of coastal wetland loss in the Texas Chenier Plain, U.S.A.
We characterized coastal wetland responses to flooding stress by measuring vegetation cover, wetland elevation and water elevation in healthy and degrading wetlands dominated by Spartina patens. Wetland elevation was measured using real-time kinematic survey methods. Vegetation cover was determined by visual estimation methods, and water elevation was measured using in situ continuous recorders. I
Temperature thresholds for black mangrove freeze damage, mortality, and recovery: refining tipping points for range expansion in a warming climate
To advance understanding of mangrove range dynamics in eastern North America, there is a need to refine temperature thresholds for mangrove freeze damage, mortality, and recovery. Here, We integrated data from 38 sites spread across the mangrove range edge in the Gulf of Mexico and Atlantic coasts of the southeastern United States, including data from a regional collaborative network called the Ma

Temperature thresholds for leaf damage from two extreme freeze events (2018 and 2021) near the northern range limit of black mangroves (Avicennia germinans) in southeastern North America
Extreme winter temperatures govern the northern range limit of black mangroves (Avicennia germinans) in southeastern North America. There is a pressing need for studies that advance our understanding of how extreme cold temperature events affect mangroves near their range limits. However, such events are infrequent and challenging to study at regional scales. Here, we compared the damage to mangro

Soil elevation change in mangrove forests and marshes of the greater Everglades: A regional synthesis of surface elevation table-marker horizon (SET-MH) data
Coastal wetlands adapt to rising seas via feedbacks that build soil elevation, which lead to wetland stability. However, accelerated rates of sea-level rise can exceed soil elevation gain, leading to wetland instability and loss.

Reply to comment by R. Parkinson on “Increasing rates of carbon burial in southwest Florida coastal wetlands” by J. Breithaupt et al.
Breithaupt et al. (2020) investigated why rates of organic carbon (OC) burial in coastal wetlands appear to increase over the past ∼120 years. After comparing dating methods and applying biogeochemical analyses, we concluded that neither dating method nor carbon degradation contribute to the observed trend. Rather, we concluded that OC burial has increased in the past century. Parkinson's (2021) C
