Most of the time, the swamp occupies, in a valley, the part abandoned by the waters of a river, like old meanders, beds previously very wide and soon reduced by some cause that has affected the flow of the river. Swamps can be freshwater or saltwater and tidal or not.
When sediments fill the bottom of the swamp, aquatic vegetation is gradually being replaced by scrubland and sometimes by mainland species with grasses and larger trees that sink their roots into the bottom rich in organic deposits.
Freshwater or salt marshes provide habitats for nesting and wintering for seabirds, small mammals, frogs, crocodiles, insects and many other hydrophilic species.
In semi-desert regions it is not uncommon for endorheism to result in the formation of extensive marshes whose area is subject to enormous seasonal variations.
In other types of marshes, water flows through channels, but runs only during periods of thawing or heavy precipitation which generates the existence of mud, sediments and nutrients in the marsh, and in turn influences seasonally varying depth of marshy water.
These are all very nice Oscar – I have none worthy of adding next to them (lol). I’m trying to catch up from a period of digital inactivity. I know I missed some of your posts. #1 has an absolutely gorgeous kind of minimalism. Perfecto!
