The flood plain near Dahan River's Chenglin Bridge used to be a garbage burial site. This was removed and the area was turned into the Lujiao River Manmade Wetlands, giving it natural purification qualities and achieving rare riverbank reforestation. After the renovations dozens of birds and insects moved into the diverse new habitat. To enjoy these natural surroundings, many people cycle through the adjacent riverside bike path. If you visit, watch carefully for spot-billed ducks, white herons, night herons, African sand martins, whiskered terns, and other water birds.
