Rising seas could cross thresholds for initiating coastal wetland drowning within decades across much of the United States
Accelerated sea-level rise is an existential threat to coastal wetlands, but the timing and extent of wetland drowning are debated. Recent data syntheses have clarified future relative sea-level rise exposure and sensitivity thresholds for drowning. Here, we integrate these advances to estimate when and where rising sea levels could cross thresholds for initiating wetland drowning across the conte
Vegetation-generated turbulence does not impact the erosion of natural cohesive sediment
Previous studies have demonstrated that vegetation-generated turbulence can enhance erosion rate and reduce the velocity threshold for erosion of non-cohesive sediment. This study considered whether vegetation-generated turbulence had a similar influence on natural cohesive sediment. Cores were collected from a black mangrove forest with aboveground biomass and exposed to stepwise increases in vel
Review of the life history and conservation of federally endangered plant species of the Lower Rio Grande Valley, Texas, U.S.A.
This review aims to summarize information critical to the conservation of the federally listed endangered species of South Texas, which occur along the border of Texas and Mexico. This paper describes the characteristics, habitat, population status, distribution, life history, threats, and restoration of endangered plant species of the Lower Rio Grande Valley, Texas, which includes Cameron, Willac

Avifauna Surveys of the Northern Main Chandeleur Islands
USGS WARC ecologists are assisting partners in conducting avian surveys on Chandeleur Islands during the pre-restoration monitoring phase to document threatened and endangered species, species richness and diversity, species abundance, and habitat use.
Vertical Control of Rod Surface Elevation Table (RSET) Benchmarks to Assess Implications of Sea-Level Rise within Texas Coastal Refuges
The USGS will establish Rod Surface Elevation Tables at five National Wildlife Refuges on the Texas coast. This work will support climate adaptation and resilience planning by identifying areas susceptible to loss and degradation due to sea-level rise and extreme climatic events along the Texas Gulf Coast.
Salinity, Flooding, and Urban Impacts to Critical Habitat of the Endangered Red-cockaded Woodpecker
USGS researchers will collect data on salinity, water level, and flooding duration within Big Branch National Wildlife Refuge to improve the understanding of the hydrologic system, and how hydrology drives available red-cockaded woodpecker habitat use and availability across the landscape.
