The studiy was carried out in Autunm from 1993 to 1995 in Liangshui Natural Reserve in NE China. After eating some seeds, Nuterackers fly over 1 km or more to some area with seeds in its sublingual pouch and cache the seeds in the ground for future use. Each cache contains 1-7 seeds commonly. Caching habitats are in accord with seedlings sites. The quantities of caching seeds are very large. Caching depth is adaptable for seed germination. The Eurasian Nutcrackers have an important effect on seeds dispersal of Korean pine.
