Latest Tidal marsh Stories
Salt marshes have been disappearing over the past two decades and a group of American researchers has shown that an influx of phosphorus- and nitrogen-based nutrients is partly to blame.
A new study, led by PRBO Conservation Science (PRBO), projects a bleak future for San Francisco Bay's tidal marshes under high-end sea-level rise scenarios that are increasingly likely.
Rising atmospheric carbon dioxide is largely responsible for recent global warming and the rise in sea levels. However, a team of scientists, including two Smithsonian ecologists, have found that this same increase in CO2 may ironically counterbalance some of its negative effects on one of the planet's most valuable ecosystemsâ€”wetlands.
A salt marsh, also otherwise known as a coastal salt marsh or a tidal marsh, is a coastal ecosystem in the upper coastal intertidal zone that lies between the land and the open salt water or brackish water that is routinely flooded by the tides. It’s dominated by dense stands of salt-tolerant plants, for example, herbs, grasses, or low shrubs. These plants originate from all around the globe and are important to the stability of the salt marsh in trapping and binding sediments. Salt marshes...
