The Pendeba Society, with generous support from Lao Niu Foundation, plans to transform conventional corrals along Pengqu River into earth brick or stone corrals, which will better protect the wetland ecosystems in QNNP. Therefore, from August 1st to 8th, 2012, staff from the Pendeba Society went on a survey about conventional corrals in Chazi, Didong, Cangmuda, Dongba and Enba Villages in Tingri County and Daqu and Nailong Village in Nyalam County.
