Description complète des menacesTexte détaillé évaluation IUCNExpert
Deforestation and transformation of large parts of the forests into plantations have led to a significant decline in important native tree species. The forests of Yunnan are also under threat from increased wood collection for fuel and building supplies and loss of habitat due both to increasing development and continuing poverty.
