ʻO nā ʻāina wai ephemeral nui ma Poyang Lake, i hana ʻia e nā loli nui o ke kau i ka pae wai, ʻo ia ke kahua hoʻoilo nui no nā Anatidae neʻe i Kina. ʻO ka emi ʻana o ka ʻāina pulu i nā makahiki he 15 i hala iho nei ua alakaʻi ʻia i nā manaʻo e kūkulu i Poyang Dam e mālama ai i nā kiʻekiʻe o ka wai hoʻoilo i loko o ka loko. ʻO ka hoʻololi ʻana i ka ʻōnaehana hydrological kūlohelohe e pili ana i nā manu wai e hilinaʻi ana i nā loli pae wai no ka loaʻa ʻana o ka meaʻai a me ka hiki. Ua hahai mākou i ʻelua mau ʻano kuisa me nā ʻano hana hānai ʻokoʻa (ʻoi aku ka nui o ka geese keʻokeʻo i mua o Anser albifrons [nā ʻano ʻai] a me ka geese swan geese Anser cygnoides [nā ʻano mea hānai tuber]) i ʻelua hoʻoilo me nā pae wai ʻokoʻa (ka hoʻomau mau ʻana i ka makahiki 2015; hoʻomau ka wai kiʻekiʻe i 2016, e like me nā hopena o ka wai i koho ʻia ma luna o ka wai i koho ʻia ma hope o Poigayang Dam). nā mea kanu a me ke kiʻekiʻe. I ka makahiki 2015, ua hoʻohana nui nā kuʻi keʻokeʻo i mua i nā ʻōpala i hana ʻia, e ʻai ana i nā ʻōpala graminoid pōkole, ʻoiai ʻo ka geese swan e ʻeli i nā substrate ma ka lihi wai no nā ʻuala. Hōʻike ʻia kēia ecotone koʻikoʻi koʻikoʻi i ka meaʻai subaquatic a kākoʻo i ka ulu ʻana o ka graminoid mua i ka wā o ka emi ʻana o ka wai. I loko o ka pae wai kiʻekiʻe i 2016, ua koho ʻia nā ʻano ʻelua i nā lepo lepo, akā i kahi ʻoi aku ka nui o nā wahi noho me nā swards graminoid kau lōʻihi no ka mea ua kaupalena ʻia ke komo ʻana i nā ʻuala a me ka ulu ʻana o ka graminoid hou ma lalo o nā kūlana wai kiʻekiʻe. Hāʻawi nā ʻāpana graminoid lōʻihi i ka ʻai ʻoi aku ka maikaʻi no nā ʻano ʻelua. ʻO ka hōʻemi nui ʻana i ka noho kūpono a me ka hoʻopaʻa ʻia ʻana i nā meaʻai liʻiliʻi e nā kiʻekiʻe o ka wai e hōʻemi i ka hiki o nā geese e hōʻiliʻili i nā hale momona kūpono no ka neʻe ʻana, me nā hopena hiki ke lawe i ke ola a me ka hana hou ʻana. Hōʻike kā mākou mau hopena e mālama ʻia nā kiʻekiʻe o ka wai ma Poyang Lake i ke kauwela, akā e ʻae ʻia e emi mālie, e hōʻike ana i nā wahi hou i ka wā hoʻoilo e hoʻolako ai i nā manu wai mai nā guild hānai āpau.
