Healthy salt marsh. In salt marshes, early ecologists like Eugene Odum and John Teal sparked the current bottom-up paradigm in ecology through work on Sapelo Island, GA (U.S.A) that stressed the dominant role of physical factors like temperature, salinity, and nutrients in regulating plant primary productivity and ecosystem structure (Teal 1962, Odum 1971).
High salt marsh dieback, or salt marsh browning, is the primary force in salt marsh degradation in the high marsh. The general effect is that the plants in the marsh die off and brown, leaving dead organic matter, and ultimately open sediment. Without strong plant roots holding the sediment, these open areas of land erode, causing the salt ...
Coastal wetlands, such as salt marshes, can sequester carbon at a rate up to ten times that of a mature tropical forest. [9] Through photosynthesis, marsh vegetation capture large amounts of carbon dioxide from the atmosphere. [9] This carbon is stored in plant tissues and soil for hundreds or thousands of years. [9]
Peat swamp forests are typically surrounded by lowland rain forests on better-drained soils, and by brackish or salt-water mangrove forests near the coast. They are a kind of peatland , which store and accumulate vast amounts of carbon as soil organic matter —much more than forests on mineral soil (i.e. non-peatland) contain.
A “managed realignment” scheme at Abbotts Hall in 2002 saw old sea walls breached in five spots along a 3km (1.9 mile) stretch to create nearly 50 hectares of new saltmarsh and intertidal ...
Mangrove forests are also effective at carbon sequestration and storage. [2] [9] [10] The success of mangrove restoration may depend heavily on engagement with local stakeholders, and on careful assessment to ensure that growing conditions will be suitable for the species chosen. [4]
The salinity levels in brackish marshes can range from 0.5 ppt to 35 ppt. [2] Marshes are also characterised by low-growing vegetation and bare mud or sand flats. [3] Due to the variations in salinity, brackish marshes create a distinctive ecosystem where plants from either freshwater or saltwater marshes can co-inhabit. [4]
Solar panels atop Ohio State’s Recreation and Physical Activity Center form a block O shape. The university has struggled to make progress on sustainability goals it set for itself in 2015.
