U.S. state agencies also may intentionally flood dry areas to encourage wetland formation to host wetland-dependent species. Steam or mist would be great too. Wetlands can form naturally or through animal or human activity. Like marshes, they are often found near rivers or lakes and have mineral soil that drains very slowly. Inland/Non-tidal Wetlands They are usually teeming with plant and animal life, because of the omnipresent water, but they needn't be: without an inflow of fresh nutrients a wetland can be a tough place to get nutrients. A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail. Aspen trees, a primary food source for beavers, grow in the wet soils along the streams.

Seacoasts will have salt marshes (e.g., the U.S. mid-Atlantic coast) or saltwater swamps (e.g., the mangrove swamps of Florida). Strange life forms would eventually adapt to life there, like the thermophiles of Old Faithful. There are two major types of peatlands – bogs and fens, both of which occur in similar climatic and geographic regions. They tend to be small and compact. Bayous usually exist in low lying areas close to the ocean. The Okefenokee is a huge depression, shaped like a gentle saucer tilting south. There are additional factors (soil depth, soil fertility, grazing from large animals), but the main one is rainfall. How are Bayous Formed? Rainfall in iron-rich uplands would flow down to wetlands and accumulate, aided by bacteria, into lumps of hematite.

Glad to help! Coal is formed from plant matter that accumulated for a period of millions of years. MathJax reference. Wetlands are where the water table is at or near the surface of the land, or where the land is permanently or temporarily (as with the tides) covered by water. Tides may cause water flow to stop or reverse direction and the water can be brackish, a mixture of freshwater and seawater.

The Okefenokee Swamp is not technically a swamp. There are two main types of swamps: freshwater swamps and saltwater swamps. Mangrove swamps, with salt-loving shrubs or trees, are common in tropical climates, such as in southern Florida and Puerto Rico. The Wanaket Wildlife Area, managed by the Confederated Tribes of the Umatilla, is a network of wetlands created through irrigation of pastureland that provides important habitat for many wetland-dependent species. It's about 20 miles long, by roughly 10-15 miles wide. Mangrove swamps are coastal wetlands found in tropical and subtropical regions. Right now.] Some tidal freshwater wetlands form beyond the upper edges of tidal salt marshes where the influence of salt water ends.

Wetlands are transitional lands between lands and other bodies of water. This may be surprising: for pre-industrial societies, marshes were a key source of iron ore! Wildlife, such as alligators and poisonous snakes, add dangerous risks to studying these fascinating wetlands. The water can of course come from rain, but it can also bubble up from the ground (rain in higher elevations trickles down and emerges from aquifers in the area of the wetland), or flow in from adjacent bodies of water like the sea, a river, or a lake.

This alters the habitat and attracts organisms that thrive in continuously wet conditions. The dominating factor for the formation of a swamp is terrain. Plants that are able to tolerate tidal flooding, such as mangrove trees, begin to grow and soon form thickets of roots and branches. Swamps are of each extremein the time that they exist: a swamp with a good water source and littledisturbance can exist longer than a mountain range. Salt swamps are formed by seawater flooding and draining, which exposes flat areas of intertidal land. Thank you, this is exactly the kind of answer I was looking for.

Swamps can be saltwater, fresh water, or a brackish in-between. If you want a marsh in a rainy area, you can declare the soil is too exhausted and the migrating muck-beasts eat any saplings. If you want a swamp in a relatively dry area, you can declare the soil to be richly endowed, and the trees to be very hardy and slow-growing, able to cope with dry spells. Here's my question. I suppose you could have a salt marsh inland, if its water came through large salt deposits, but if so it may not have much life since there'd be no way for saltwater plants or animals to migrate to it.
