The species is not recorded as a threatened species in IUCN (2017). Although only three fruiting individuals of Q. bella were collected in Ba Vi National Park, more individuals are expected to occur there and the habitat in the Ba Vi National Park is currently well-protected from anthropogenic activities under the law. Thus, it is appropriate to place this species under the category Least Concern (LC) following IUCN Red List (IUCN 2012) and Vietnam Red Data book (Ban et al. 2007).</p> </div>	https://treatment.plazi.org/id/EE464698F900583587155F201064C04A	Public Domain	No known copyright restrictions apply.
