Abstract
The aerial part of Ephedra sinica Stapf growing in a natural habitat were cut early in the spring for the purpose of examining the effects of herbivory damage by livestock including sheep and goats. The results showed that the plants never generated new stem afterwards in the same year after cutting the aerial parts and did not make cones. In the next season, the plant became small in size and scarcely made cones. Through this study, it was confirmed experimentally that the herbivoly damage to plant growth of E. sinica by livestock was serious.
