Natural filtration and flood control make wetlands valuable.
Wetlands serve as filters for surface and groundwaters.
They provide vital habitat for many species of plants and animals, serve as recreational areas and help in natural flood control. Wetland areas must be defined and delineated at the beginning of any golf course design process. During construction they must be protected from excess water and sedimentation. Once the course is built they should be managed as natural areas which are protected from abnormal volumes of water, nutrients or pesticides used in the maintenance of the course. Minimize the flow of irrigation water into the wetlands.
