ʻO nā wahi pulu ephemeral ākea ma ka loko ʻo Poyang, i hana ʻia e nā loli kau nui i ka pae wai, ke kahua hoʻoilo nui no ka poʻe Anatidae neʻe ma Kina. ʻO ka emi ʻana o ka wahi pulu i nā makahiki 15 i hala iho nei ua alakaʻi i nā manaʻo e kūkulu i kahi Poyang Dam e mālama i nā pae wai hoʻoilo kiʻekiʻe i loko o ka loko. ʻO ka hoʻololi ʻana i ka ʻōnaehana hydrological kūlohelohe e hoʻopilikia i nā manu wai e hilinaʻi ana i nā loli pae wai no ka loaʻa ʻana o ka meaʻai a me ke komo ʻana. Ua hahai mākou i ʻelua ʻano ʻonika me nā ʻano hānai like ʻole (nā ʻonika keʻokeʻo nui ʻo Anser albifrons [nā ʻano ʻai] a me nā ʻonika swan Anser cygnoides [nā ʻano hānai tuber]) i nā hoʻoilo ʻelua me nā pae wai like ʻole (ka emi mau ʻana i ka makahiki 2015; ka wai kiʻekiʻe i hoʻomau ʻia i ka makahiki 2016, e like me nā mea i wānana ʻia ma hope o ka Poyang Dam), e noiʻi ana i nā hopena o ka loli ʻana o ka pae wai i kā lākou koho ʻana i kahi noho ma muli o nā mea kanu a me ke kiʻekiʻe. I ka makahiki 2015, ua hoʻohana nui nā ʻonika keʻokeʻo i nā ʻāina lepo, e hānai ana i nā ʻōpala graminoid pōkole momona, ʻoiai nā ʻonika swan i ʻeli i nā substrates ma ka lihi wai no nā ʻōmole. Hoʻopuka mau kēia ecotone koʻikoʻi i ka meaʻai subaquatic a kākoʻo i ka ulu ʻana o ka graminoid mua i ka wā o ka emi ʻana o ka pae wai. I ka wā o ka pae wai kiʻekiʻe i ka makahiki 2016, ua koho nā ʻano ʻelua i nā pāpū lepo, akā i kahi pae nui o nā wahi noho me nā swards graminoid kau i hoʻokumu ʻia no ka mea ua kaupalena ʻia ke komo ʻana i nā ʻōpuʻu a me ka ulu ʻana o ka graminoid hou ma lalo o nā kūlana wai kiʻekiʻe.
