Distribution and Habitat
The species is widespread in China (Jiangsu, Anhui, Qinghai, Gansu, Shaanxi, Shanxi, Henan, Shandong, Hebei, Liaoning, Jilin and Heilongjiang provinces, as well as Inner Mongolia, Ninxia-Hui and Xinjiang-Uigur autonomous regions), Mongolia, Korea and Russian East Siberia (Baikal Lake area: Buryatia, Chita Province and Irjutsk Province - Goloustnaya River delta, Maloe More Bay and Olkhon Island at about 53oN, 107o30'E - the northernmost locality; the Far East: the Amur and Ussuri Rivers and their tributaries).
Bufo raddei inhabits the edges of coniferous and deciduous forests, groves, bushlands, different types of meadows, forest steppes and steppes with sandy, rocky and alluvial soils. The species is abundant in many settlements, some cities and in agricultural landscapes. It occurs both in wet and in dry habitats. Even in the steppe zone, it can occur not only near water bodies (rivers, ponds, lakes etc.), but at a considerable distance from water. However, in dry and continental desert areas the toad is tied to lakes and other permanent water sources. Such populations often are isolated from other populations by vast areas unavailable for amphibians. Spawning occurs in lakes and ponds with stagnant water.
