Kuti tidziwe tsatanetsatane wa kusankhidwa kwa malo ndi mitundu yanyumba ya cranes zakuda (Grus nigricollis) ndi momwe msipu umawakhudzira, tidawona achinyamata amtundu wa anthu akutsata satellite mdera la Danghe la Yanchiwan National Nature Reserve ku Gansu kuyambira 2018. mpaka 2020 m'miyezi ya Julayi-Ogasiti. Kuwunika kwa chiwerengero cha anthu kunachitikanso panthawi yomweyi. Mtundu wakunyumba unayesedwa ndi njira zoyezera kuchuluka kwa kernel. Kenako, tidagwiritsa ntchito kutanthauzira kwazithunzi zakutali ndi kuphunzira pamakina kuti tizindikire mitundu yosiyanasiyana ya malo omwe ali m'dambo la Danghe. Mawerengedwe osankhidwa a Manly ndi mtundu wa nkhalango mwachisawawa adagwiritsidwa ntchito kuti awunike kusankha malo okhala m'malo osiyanasiyana komanso malo okhala. M'dera lophunzirira, ndondomeko yoletsa kudyetserako ziweto idakhazikitsidwa mu 2019, ndipo kuyankha kwa ma cranes a makosi akuda akuwonetsa motere: a) kuchuluka kwa ma cranes ang'onoang'ono kudakwera kuchoka pa 23 mpaka 50, zomwe zikuwonetsa kuti kudyetserako ziweto kumakhudza kulimba kwa cranes; b) Kudyetserako ziweto sikumakhudza malo okhala ndi kusankha kwa malo okhala, koma kumakhudza momwe crane imagwiritsira ntchito malo monga momwe chiwerengero cha malo odyetserako chikuyendera chinali 1.39% ± 3.47% ndi 0.98% ± 4.15% mu 2018 ndi 2020 zaka, motsatana; c) Panali kuchulukirachulukira kwa mtunda woyenda tsiku ndi tsiku komanso kuthamanga kwanthawi yomweyo kumawonetsa kuwonjezereka kwamphamvu kwa ma cranes ang'onoang'ono, ndipo chiŵerengero cha ma cranes osokonekera chimakula; d) Zosokoneza za anthu sizimakhudza kusankha malo okhala, ndipo ma cranes sakhudzidwa kwenikweni ndi nyumba ndi misewu pakadali pano. Ma cranes adasankha nyanja, koma kufananiza mitundu yanyumba ndi kusankha kwa malo okhala, madambo, mitsinje ndi mapiri sizinganyalanyazidwe. Choncho, tikukhulupirira kuti kupitiriza ndondomeko yoletsa kudyetserako ziweto kudzathandiza kuchepetsa kuphatikizika kwa madera a m'nyumba ndi kuchepetsa mpikisano wa intraspecific, ndiyeno kumawonjezera chitetezo cha kayendedwe ka ma cranes ang'onoang'ono, ndipo pamapeto pake kumawonjezera chiwerengero cha anthu. Kuphatikiza apo, ndikofunikira kuyang'anira zotengera zamadzi ndikusunga misewu ndi nyumba zomwe zilipo m'madambo onse.
