Ecological Stressors
Ecological Stressors
USGS WARC scientists study environmental and anthropogenic (human-caused) stressors, such as hurricanes and climate change, that potentially impact the health and productivity of lands and waters of management concern.

Structured Decision-Making to Facilitate Multi-Stakeholder Coastal Conservation and Restoration under Climate Change Uncertainties: Case Study on Barrier Island of the Northern Gulf of Mexico
Barrier island resource managers within the northern Gulf of Mexico have the opportunity to more directly incorporate scientific uncertainties and technological challenges inherent with large-scale barrier island restoration projects, and as such, commit to developing robust long-term monitoring programs and applying adaptive management.
Dendrochronology of Coastal Forests to Evaluate Impacts of Wind and Surge from Hurricane Sandy
The science of dating growth rings and history of live and fossil wood samples is called dendrochronology. This technique is valuable for conducting climate reconstructions where meteorological data is lacking and for detecting past disturbance events such as tropical storms and hurricanes.
Assessing Treefall Patterns and Causal Relations of Wind and Surge from Hurricane Sandy
As tropical storms and hurricanes move onshore and make landfall, wind and storm surge can be sufficiently high to damage built-infrastructure and natural systems, most notably coastal forests at the interface of land and sea.
Aerial Videography Overflights of Forest Cover and Impact from Hurricane Sandy along the Atlantic Coast, USA
High resolution imagery (aerial videography) was obtained of Hurricane Sandy to assess forest damage by documenting disturbed canopy and downed trees.
Mekong River Fish Ecology: Information Gap Assessment and Capacity Building in Southeast Asia
The Mekong River is one of the great rivers of the world, recognized as having a freshwater fish diversity second or third to only the Amazon and Congo basins, rivers of much larger drainage area.
Investigation of Causal Mechanisms of Coastal Wetland Change in Coastal Louisiana
This task will involve the compilation of all data sources and expert knowledge of causal mechanisms of specific areas of wetland loss throughout the coastal zone of Louisiana.
Gulf of Mexico Land Loss Change Assessment: A Cooperative Study with the Bureau of Ocean and Energy Management
Eighty-five percent of the coastal wetland loss in the contiguous United States occurs in the Gulf of Mexico. Documenting and understanding the occurrence of this wetland loss will provide for effective planning, mitigation, and restoration activities.
Hyper-Temporal Land Area Change Rates in Coastal Louisiana from 1973 to 2015
This study analyzes changes in the extent of land in coastal Louisiana by using an average of 81 datasets (multiple dates of satellite data from 1973 to 2014) for summarizing land and water areas.
Hurricane Sandy Surge and Marsh Dieback in the New Jersey Coastal Zone
Detection of storm surge impacts on coastal marshes requires regional or broader mapping of surge flooding above and below the wetland canopy and estimation of abnormal change in wetland condition.
Joint Research on Water and Sedimentation Changes and Potential Impacts on Biodiversity along the Porsuk River, Turkey
The Porsuk River floodplain near Eskisehir, Turkey contains a large number of wetlands, which have been managed by humans for millennia.
Long-term Trends in Swamp Tree Growth across Drought and Salinity Gradients along the Northern Gulf Coast
This study will examine the potential effects of climate-change-induced sea level rise, drought and water extraction by examining tree growth patterns across the Gulf Coast, specifically targeting long-term research plots available in the North American Baldcypress Swamp Network (NABCSN) and the Suwannee River.
Mangroves 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.
