Word "wetland" was not generally used in American vernacular until recently.
It appears to have adopted as euphemistic substitute for the word "swamp" (Wright, 1907).
Nineteenth-century scientists used terms such as mire, bog and fen to explain the lands that are called wetlands and these terms are still used by scientists to explain definite types of wetland.
The term wetland has slowly come into common scientific use only in 2nd half of twentieth century.
Wetland is a place which is surrounded by water either seasonally or permanently. These are the place which are inundated by water. There is a separate flora and fauna ecosystem for a wetland. This flora and fauna which grows in a wetland is mainly affected on the characteristics of the wetland.
The characteristics of the fate line depends on the location primarily its latitude and longitude. But this is not only the prime factor which decides the characteristics of wetland. There are the factors also include the characteristics of a wetland like altitude and presence of surrounding water bodies.
