Abstract: Mammalian surveys，focusing on wild ungulate species，were conducted inan unprotected region of central Qinghai province called Yeniugou during 1990～1992.wiId yak，Tibetan gazelle，Tibetan antelope.and blue sheep all numbezed over 1000 during 1991；Tibetan wild ass numbered about 800.and argali about 250.Other mammalian were noted Yeniugou is an important area for Qinghal-Tibetan plateau wildlife ;probably one of the best remaining areas ,particularly for wild yak and argali. Despite legal protection，poaching for most specks is virtually uncontrolled.The most pressing need is to control
poaching by non-residents.Establishing a nature reserve in Yeniugou is a possibility,but nearby experiences suggest that，failing funding mechanisms and an in centive scheme for local people to cooperate in wildlife protection,it would not be likely to succeed.Another possibility is to establish Yeniugou as a ''wildlife management area ".These concepts are discussed．
