No ka ʻike ʻana i nā kikoʻī o ke koho ʻana i kahi noho a me ka laulā o nā cranes ʻāʻī ʻeleʻele (Grus nigricollis) a pehea e hoʻopili ai ka ʻai ʻana iā lākou, ua nānā mākou i nā lālā ʻōpio o ka heluna kanaka me ka hahai ʻana i nā satelite ma ka ʻāina pulu ʻo Danghe o ka Yanchiwan National Nature Reserve ma Gansu mai 2018 a 2020 i nā mahina o Iulai-ʻAukake. Ua mālama ʻia hoʻi ka nānā ʻana i ka heluna kanaka i ka manawa like. Ua helu ʻia ka laulā o ka home me nā ʻano kuhi ʻana o ka nui o ka kernel. A laila, ua hoʻohana mākou i ka wehewehe ʻana i ke kiʻi ʻike mamao me ke aʻo mīkini e ʻike i nā ʻano nohona like ʻole ma ka ʻāina pulu ʻo Danghe. Ua hoʻohana ʻia nā lakio koho a Manly a me ke kumu hoʻohālike ululāʻau random e loiloi i ke koho ʻana i kahi noho ma ka pae laulā o ka home a me ka pae nohona. Ma ka wahi aʻo, ua hoʻokō ʻia kahi kulekele kaupalena ʻai ʻana i ka makahiki 2019, a ʻo ka pane a nā cranes ʻāʻī ʻeleʻele e hōʻike nei penei: a) ua piʻi ka helu o nā cranes ʻōpio mai 23 a 50, e hōʻike ana i kahi ʻano ʻai e hoʻopilikia i ke olakino o nā cranes; b) ʻaʻole pili ke ʻano hānai holoholona o kēia manawa i nā wahi o ka laulā home a me ke koho ʻana i nā ʻano nohona, akā pili ia i ka hoʻohana ʻana o ka crane i ka hakahaka ʻoiai ʻo ka awelika overlap index o ka laulā home he 1.39% ± 3.47% a me 0.98% ± 4.15% i nā makahiki 2018 a me 2020, kēlā me kēia; c) aia kahi ʻano piʻi nui ma ka awelika o ka neʻe ʻana i kēlā me kēia lā a me ka wikiwiki koke e hōʻike ana i ka piʻi ʻana o ka hiki ke neʻe o nā crane ʻōpio, a ʻoi aku ka nui o ka lakio o nā crane i hoʻopilikia ʻia; d) ʻAʻole nui ka hopena o nā mea hoʻopilikia kanaka i ke koho ʻana i ka nohona, a ʻaʻole pili loa nā crane i nā hale a me nā alanui i kēia manawa. Ua koho nā crane i nā loko, akā ʻo ka hoʻohālikelike ʻana i ka laulā home a me ke koho ʻana i ka unahi nohona, ka marsh, ka muliwai a me nā kuahiwi ʻaʻole hiki ke hoʻowahāwahā ʻia. No laila, ke manaʻoʻiʻo nei mākou e kōkua ka hoʻomau ʻana i ke kulekele kaupalena hānai holoholona i ka hōʻemi ʻana i ka overlap o nā laulā home a ma hope e hōʻemi i ka hoʻokūkū intraspecific, a laila hoʻonui ia i ka palekana o ka neʻe ʻana o nā crane ʻōpio, a i ka hopena e hoʻonui i ke olakino o ka heluna kanaka. Eia kekahi, he mea nui e hoʻokele i nā kumuwaiwai wai a mālama i ka hoʻolaha ʻana o nā alanui a me nā hale ma nā wahi pulu.
