Located in Ilan County's Yuanshan at an elevation of only 500 meters, Shuanglienpi doesn't have frost in the winter, so less hardy water plants won't die from cold there. And in the summer the ample fog can help stem the spread of invasive plants.
位於宜蘭縣員山鄉，海拔 500 公尺的雙連埤，冬天不結霜，使弱勢水草不會凍死；夏季多雲霧，則可以抑制強勢草種的大量繁衍。
