How is a wetland defined?

A wetland is defined as an area that experiences temporary or persistent water presence, supporting a distinct ecosystem. This characteristic differentiates wetlands from completely dry areas or those that are permanently submerged. The presence of water can be seasonal or variable, contributing to unique soil conditions and a specific array of plant and animal life adapted to these environments.

Wetlands play a crucial role in the environment, acting as natural water filters, flood control zones, and habitats for a diverse range of species. Their ability to retain water and moderate flood dynamics is essential to maintaining ecological balance.

Some other definitions or descriptors may not accurately encompass the nature of wetlands. Areas that are fully submerged in water do not represent the typical characteristics of wetlands, which can include both waterlogged soils and zones that may exhibit periodically dry conditions. While wetlands can sometimes be used for agricultural purposes, they are not primarily defined by such usage. Areas of dry land with high rainfall do not meet the criteria for wetlands, as these areas lack the standing water or saturated soils that define wetland ecosystems.
