In the Kuantu wetlands area, already designated as a natural preserve, the Taipei City government had originally planned to buy the land inside the dikes and had mapped it out as the "Kuantu Nature Park," but because land prices lurched upward, they have not been able to finalize the plan; the 55 hectares of wetlands outside the dikes are already wasteland, a place where people dump their garbage.
已被指定為自然保護區的關渡沼澤地，台北市政府原計畫購買堤防內的土地，規劃為「關渡自然公園」，卻因地價節節上漲，遲遲未能定案；堤防外五十五公頃沼澤濕地則成為廢土、垃圾傾倒處。
