Kugawidwa kwa chakudya ndi chinthu chofunikira kwambiri pakusankha malo okhala. Mbalame za herbivorous waterbirds zimakonda zomera zomwe zimakula msanga (kuyambira pamene zomera zimakula mpaka kufika pachimake cha zakudya zowonjezera) chifukwa zimapatsa mphamvu zowonjezera mphamvu. Gawo lachitukuko la zomerali silinapezeke mokwanira ndi zizindikiro za zomera zomwe zimagwiritsidwa ntchito pa satana, zomwe zimayang'ana kwambiri za zomera (mwachitsanzo, Enhanced Vegetation Index, EVI) kapena kukula kwa zomera (mwachitsanzo, kusiyana kwa EVI pakati pa masiku ano ndi apitawo, diffEVI). Pofuna kukonza mapu a malo odyetserako msipu wa mbalame za m'madzi, tikupangira chizindikiro chatsopano cha kukula kwa mbewu pogwiritsa ntchito satellite cha early-stage plant growth (ESPG). Timalingalira kuti mbalame zam'madzi zimakonda zomera zidakali zoyamba kukula ndipo zimasankha zomera zomwe zimakhala ndi mapeto a ESPG panthawi yomwe sizikukula. Timagwiritsa ntchito satellite kutsatira atsekwe 20 akutsogolo koyera (Anser albifrons) nthawi yozizira mumtsinje wa Yangtze kuti titsimikizire zolosera zathu. Timamanga mizere yofananira yogawira tsekwe munthawi yomwe ikukula komanso yosakula ndikuyerekeza momwe ESPG imagwirira ntchito ndi zofananira zakukula kwa zomera (EVI ndi diffEVI). M'nyengo yakukula, ESPG imatha kufotokoza 53% ya kusiyana kwa tsekwe, EVI (27%) ndi diffEVI (34%). M'nyengo yosakula, kutha kwa ESPG kokha kumakhudza kwambiri kagawidwe ka tsekwe, kufotokoza 25% ya kusiyana (ESPG: AUC = 0.78; EVI: AUC = 0.58; diffEVI: AUC = 0.58). Chizindikiro chatsopano chakukula kwa mbewu ESPG chitha kugwiritsidwa ntchito kukonza mitundu ya mbalame zam'madzi zomwe zimagawika m'madzi ndikuthandizira kuyesetsa kuteteza mbalame za m'madzi ndi kasamalidwe ka madambo.
