The Yilan River [1] is a tributary of the Lanyang River in Yilan County, northeast Taiwan.[2] It flows through Yilan for 25 kilometers.
Three turtle species occur in the Yilan River: the native Chinese stripe-necked turtle and yellow pond turtle, and the introduced red-eared slider, which outnumbers the native species. Glass eels of two eel species, Anguilla japonica and Anguilla marmorata, are found in the river.
