locality; a series of fields, currently used to cultivate garlic and onions. The site lies just north of Tzeng-Wen Creek, which shaped the landscape in this area. The fields are flood irrigated, and actively ploughed, planted and harvested. The site is probably also subject to the application of fertilisers and pesticides. The fields are inundated either by irrigation or monsoonal rains from May through September or October, when air temperatures are between 29 to 32˚C. Active clam shrimp are found throughout the inundation period, becoming scarcer later in the season.
