Malo okhala ndi malo okhala ndi zinthu zofunika kwambiri pa chilengedwe cha mbalame, ndipo maphunziro okhudza izi athandiza pakusunga ndi kuyang'anira kuchuluka kwa mbalame. Nsomba 67 zinali dongosolo loyika malo padziko lonse lapansi lolembedwa ku Sanmenxia Wetland ku Henan Province kuti apeze zambiri za malo m'nyengo yozizira kuyambira 2015 mpaka 2016. Kukula kwa malo okhala a nswana kunali kwakukulu kwambiri pakati pa nyengo yozizira ndipo kutsatiridwa ndi nthawi yoyambirira ndi nthawi yomaliza, ndipo kukula kwake kunali kosiyana kwambiri pakati pa nthawi zitatu za nyengo yozizira. Panali kusiyana kwakukulu pakugwiritsa ntchito malo okhala pakati pa nthawi zosiyanasiyana za nyengo yozizira. Poyamba, nswana zinkagwiritsa ntchito udzu wa m'madzi ndi madera a zomera zomwe zimamera, ndipo zinkadalira kwambiri zowonjezera zopangidwa chifukwa cha kusowa kwa malo odyetsera zachilengedwe pakati pa nthawi yapakati. Pamapeto pake, nswana zinkagwiritsa ntchito makamaka malo a udzu watsopano wa padziko lapansi. Kupatula madzi akuya, kugwiritsa ntchito madzi ena kunali kosiyana kwambiri pakati pa nthawi zosiyanasiyana za nyengo yozizira. Poyamba nyengo yozizira, nswana zimakonda madera otsika ndi okwera madzi; Pakati pa nthawi yapakati, anali makamaka m'madera apakati ndi okwera kwambiri ndipo ankagwiritsa ntchito madera onse otsika madzi kupatulapo madzi akuya kumapeto kwa nyengo yozizira. Zinatsimikiziridwa kuti zomera zina zimakondedwa ndi swans, monga bango, cattails ndi udzu wa m'munda, ndipo kuya kwa madzi kuyenera kukhala koyenera kwa swans, ndi kuchuluka kwa madzi kumasiyana pa gradient.
