Salt marsh elevation and responses to future sea-level rise in the Knysna Estuary, South Africa
Sea-level rise is a significant threat to salt marshes. However, these habitats can respond by increasing their relative elevation, or by migrating into adjacent areas. Here we provide the first
Coastal Wetland Distributions: Delineating Domains of Macroscale Drivers and Local Feedbacks
How do multiple stable states influence local and macroscale ecological patterns? Understanding how local feedbacks operate within heterogeneous coastal environments is essential to forecasting marsh
The Potential Resiliency of a Created Tidal Marsh to Sea Level Rise
Abstract. The purpose of this study was to determine the elevation dynamics of a created tidal marsh on the North Carolina coast. Deep rod surface elevation tables (RSET) and feldspar marker horizons
Divergence of Sediment Fluxes Triggered by Sea‐Level Rise Will Reshape Coastal Bays
Sediment budget and sediment availability are direct metrics for evaluating the resilience of coastal bays to sea‐level rise (SLR). Here we use a high‐resolution numerical model of a tidally
Sediment Supply Explains Long‐Term and Large‐Scale Patterns in Salt Marsh Lateral Expansion and Erosion
Salt marshes often undergo rapid changes in lateral extent, the causes of which lack common explanation. We combine hydrological, sedimentological, and climatological data with analysis of historical
Salt Marsh Migration Potential at Cape Cod National Seashore (Massachusetts, U.S.A.) in Response to Sea-Level Rise
ABSTRACT Smith, S.M., 2020. Salt marsh migration potential at Cape Cod National Seashore (Massachusetts, U.S.A.) in response to sea-level rise. Journal of Coastal Research, 36(4), 771–779. Coconut
A Marsh Against Tide: The Impact of Nitrogen Enrichment on Salt Marsh Platform Elevation in the Great Sippewissett Marsh
Recent studies predict that salt marshes will disappear from the Cape Cod landscape by the end of the century. A highly debated piece of this equation is the effect of nitrogen pollution on rates of


Limits on the adaptability of coastal marshes to rising sea level
Assumptions of a static landscape inspire predictions that about half of the world's coastal wetlands will submerge during this century in response to sea‐level acceleration. In contrast, we use
Anthropocene Survival of Southern New England’s Salt Marshes
This collection offers lessons that will be of use to researchers and managers on coasts where relative sea level is not yet rising as fast as in southern New England, and changes in marsh-building processes, patterns of vegetation loss, and shifts in species composition are highlighted.
Salt marsh ecosystems are maintained by the dominant macrophytes that regulate the elevation of their habitat within a narrow portion of the intertidal zone by accumulating organic matter and
Coastal eutrophication as a driver of salt marsh loss
It is shown that nutrient levels commonly associated with coastal eutrophication increased above-ground leaf biomass, decreased the dense, below-ground biomass of bank-stabilizing roots, and increased microbial decomposition of organic matter, demonstrating that nutrient enrichment can be a driver of salt marsh loss.
Elevation change and the vulnerability of Rhode Island (USA) salt marshes to sea-level rise
Salt marshes persist within the intertidal zone when marsh elevation gains are commensurate with rates of sea-level rise (SLR). Monitoring changes in marsh elevation in concert with tidal water
Vegetation Change in Salt Marshes of Cape Cod National Seashore (Massachusetts, USA) Between 1984 and 2013
Vegetation patterns in salt marshes are largely based on elevation in relation to tidal flooding. In New England salt marshes, vegetation is distinctly zoned into species that occur in the high marsh
Vegetation Dynamics in Rhode Island Salt Marshes During a Period of Accelerating Sea Level Rise and Extreme Sea Level Events
Sea level rise is a major stressor on many salt marshes, and its impacts include creek widening, ponding, vegetation dieback, and drowning. Marsh vegetation changes have been associated with sea
