Description complète des menacesTexte détaillé évaluation IUCNExpert
Soil erosion, water shortages and deforestation are major threats to the environment in the Qinghai Province, China. These threats are cause by extensive agriculture and mining activity. As this species is found growing in this area, it may be threatened by these environmental issues. In Sichuan Province, scrub land is heavily impacted by grazing from livestock such as yak, sheep and goats. Illegal logging in the forests as well as overgrazing has led to serious erosion on steep slopes in the western part of the Sichuan mountains. Increasing development and tourism in Sichuan Province is also expected to have negative impacts on the environment such as habitat degradation.
