Description complète des menacesTexte détaillé évaluation IUCNExpert
Quercus bawanglingensis occurs in natural forest areas on Hainan province which is threatened by habitat destruction. A 2015 study by Zhai et al. found that Hainan province has seen a loss in natural forest area and an increase in rubber plantation area between 1995 and 2005. The study noted that the trend occurred in protected areas as well. The loss of natural forest and increase in area for rubber plantations leads to habitat destruction and fragmentation for species that rely on natural forest habitat.

Mesures de conservation recommandéesStratégies de conservation IUCNExpert
More survey work is needed to determine the full population of the species and monitor population trends. Additionally, it is recommended that there be increased enforcement of natural forest protection to avoid further habitat degradation. Quercus bawanglingensis is not listed in any ex situ collections (BGCI 2020).
