What is a wetland?What is a wetland?

Wetlands are areas that are too wet to be Wetlands are areas that are too wet to be considered land but not wet enough to be considered land but not wet enough to be considered lakes. They have poor considered lakes. They have poor drainage for the soil and no clear banks or drainage for the soil and no clear banks or beds like lakes. Wetlands can be beds like lakes. Wetlands can be permanent (there all year like ponds) or permanent (there all year like ponds) or temporary (there once in a while like temporary (there once in a while like puddles)puddles)
