Soil that has experienced severe oxygen starvation requires turning to expose it to the air. The water level must be controlled too, for if it is too high, smaller birds like sandpipers and plovers won't be able to reach their food.
此外，還要進行水位控制，否則水位太高，將使得中小型的鷸 6 科水鳥無法覓食。除了經營水鳥的覓食棲地外，「繁殖棲地」的營造、「多樣化棲地」的設計，也都循序漸進的進行，還有一些是需要保存原樣的特殊棲地。
