noun
Refers to an area of land that is permanently or seasonally saturated with water, such as a marsh or swamp. Often used in geographical or environmental contexts.

A vast wetland stretches across this region.
沼沢地の生態系は多様な生物を
The wetland ecosystem supports a variety of organisms.
沼地 refers to a 'swamp' or 'marshy land', often smaller in scale than 沼沢地, which can imply a broader wetland area.
Compound of 沼 (ぬま, 'swamp'), 沢 (さわ, 'marsh'), and 地 (ち, 'land'). The reading しょうたくち uses the on'yomi for 沼 (しょう) and 沢 (たく), combined with the on'yomi ち for 地.
