État de la populationTexte officiel évaluation IUCNExpert
Quercus bella is reported from across Guangxi province and one site in Hainan (China). It is also suggested to occur in Viet Nam, though no exact sites have been described here (any sites will presumably be in the north of the country only).

Description complète des menacesTexte détaillé évaluation IUCNExpert
Quercus bella is widespread, but not common, and there are grounds to consider that it could be a species sought after for local timber harvesting. Quercus bella occurs in natural forest areas in 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 from 1995 to 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
Studies are recommended at known localities sites, and across the distribution range, in order to assess the threats to the species. Sites currently listed could have already been cleared and this is not a species with remarkable features, thus allowing for creeping population declines by unsustainable harvesting from natural stocks. Quercus bella is not listed in any ex situ collections on BGCI PlantSearch (BGCI 2019).
