1. Morphological Study : The exact age of white-lipped deer was determined by counting the annual layers of dental cementum on the first incisor and the first molar. The results of the body size and weight measurements, 7-13 year old stags were estimated to weight from 180 to 230kg, with an average weight of 205kg. Adult does between the ages of 6 and 14 weight from 80 to 180kg, averaging 124kg. The white spots appear on newborn fawns at around one and a half months. The fossa of the inflaorbital gland is larger than that of other species including sika deer and samber. The wider nasales are also characteristics of this species. These characteristics are thought to be the result of the white-lipped deer's adaptation to the cold climate and harsh environment of the Tibetan Plateau. The characteristics of the antlers is that each tine branches off from the beam like an axil on the same plane.
2. Distribution : This deer lived from the rhododendron scrub just above the spruce forests to alpine grasslands, ranging in altitudes from 4000 to 5000m. The pasturing of domestic animals in the area influences not only the spatial distribution of the deer, but also the timing of seasonal shifts. The main distribution of the deer is in western Sichuan Province and some scattered populations in Qinghai Province are endangered.
3. Ecological Result : From the result of the fecal and rumen contents, the white-lipped deer seems to be a typical grazer. Three aggressive patterns between hinds were observed. The head down posture was the most common aggressive threat in stags, but they never displayed any form of the head up threat. Roars were the loudest and most conspicuous calls in stags during the rut and were analyzed spectrographically. The mating system was thought to be a harem type based on its behavioral characteristics.
