Why is it important to manage wetlands?

Lot of biodiversity. Lost of wetlands species is disporportionatly high compared to other ecosystems. Has many functions and values in landscape: nutrient processing (function = independant of humans like nutrient processing, values = human thinking that we like it) It reduces damage caused by floods by slowing and storing water. Good at recharging ground water in drought periods Are very involved in nutrient reemoving and unpooliting water. It thereby improves water quality. Its a habitat for plants and animals. Bird migrations are always using wetlands as stopping ground.
