We elected an area where uniform paddy cultivation is done by the overall community, and divided roughly into five rice field types; I (Rice field and lotus field mixture area), II (Pond adjoining area), III (Rotation of crops area of rice, wheat and soybean), IV (Fabricated field / Mixture of the waterway of the ground and concrete) and V(Not-fabricated field / Mixture of the waterway of the ground and concrete) in Noubi plains. We conducted a line census investigation on a ridge in order to investigate the species composition of frogs according to the rice field type. The results of our survey, there were large numbers of frogs in the areas which have a moist cultivating environment (Type I , V). In contrast, in the well-drained rice fields (Type II , III and IV) where rice seedlings were transplanted in June, there were small numbers of frogs irrespective of the environmental structure. The number of frogs in Type I where different crops (rice and lotus) were cultivated in parallel was larger than that in Type V because the waterside has always existed there.
