[Objectives] Dopasia harti is a threatened reptile mainly distributed in China, and is a national secondary key protected wild animal. So far, there is a lack of systematic studies on the resources and habitat preferences of the wild population of the D. harti. [Methods] This paper conducted a questionnaire survey of residents in Mt. Emei and the surrounding areas in 2020, and according to the results of the questionnaire, a field survey was conducted in spots where the D. harti have been found, and quadrats were set up to explore the habitat selection of D. harti in 2023. The results of the questionnaire and the proportion of each habitat factors in the field survey were statistically analyzed, and the habitat factors were analyzed using principal component analysis. [Results] The results showed that:due to habitat changes and human capture, the population of D. harti in Mt. Emei and its surrounding areas has generally declined (Table 1). The distribution of D. harti has been retreated to Gaoqiao Town, Suishan Town, Longchi Town, Huangwan Town in Emeishan City, Huatou Town in Jiajiang County, and Liujiang Town in Hongya County, Meishan City. In Mt. Emei area, the D. harti preferred to live in the evergreen broad-leaved forest of loose soil in the middle and low altitude areas (mainly 800﹣1 200 m), semi-shady and semi-sunny slope, more than 50 m from water source and more than 6 cm from herbaceous height, and the vegetation coverage rate was 10%﹣75% (Table 3). [Conclusion] According to the survey, most of the disturbance factors are road construction and planting. For the protection of D. harti, road construction should be optimized to avoid destroying the habitats of D. harti. We should also promote the cultivation of eco-friendly products and natural eco-tourism to increase the income of local people; and strengthen the popular science education of the surrounding people and improve people’s awareness of protection.
