The Potential Resiliency of a Created Tidal Marsh to Sea Level Rise

Modeling Tidal Marsh Distribution with Sea-Level Rise: Evaluating the Role of Vegetation, Sediment, and Upland Habitat in Marsh Resiliency

Tidal marshes maintain elevation relative to sea level through accumulation of mineral and organic matter, yet this dynamic accumulation feedback mechanism has not been modeled widely in the context of accelerated sea-level rise. Uncertainties exist about tidal marsh resiliency to accelerated sea-level rise, reduced sediment supply, reduced plant productivity under increased inundation, and lim...

Overwash Deposition Increases Backbarrier Marsh Resiliency to Sea Level Rise: Insights from a Coupled Barrier Island-marsh Model

Tidal marsh plant responses to elevated CO2 , nitrogen fertilization, and sea level rise.

Elevated CO2 and nitrogen (N) addition directly affect plant productivity and the mechanisms that allow tidal marshes to maintain a constant elevation relative to sea level, but it remains unknown how these global change drivers modify marsh plant response to sea level rise. Here we manipulated factorial combinations of CO2 concentration (two levels), N availability (two levels) and relative se...

Forecasting the effects of accelerated sea-level rise on tidal marsh ecosystem services

© The Ecological Society of America www.frontiersinecology.org T wetlands such as salt, brackish, and freshwater marshes provide essential ecosystem services to society. Such services include functions associated with regulation, habitat, and production (Daily et al. 1997; de Groot et al. 2002). Positioned at the interface between land and sea, tidal marshes are uniquely suited to provide ecosy...

Dispersal potential of a tidal river and colonization of a created tidal freshwater marsh

Background and aims A created tidal freshwater wetland, with no extant seed bank, was monitored to evaluate the colonization potential of a tidal river, vegetation and seed bank changes, and also species persistence. Methodology The 32.3-ha mitigation, adjacent to the Delaware River, was completed in 1994. Three sites, with differing completion dates, and three locations (channel edge, midpoint...
