Ecology in Vietnam
Quercus bella was found on the slopes in evergreen forests in Ba Vi National Park: at alt. 600–1172 m.
Phenology
Flowering from February to April, fruiting from October to December (Huang et al. 1999[1]). Flowering and fruiting specimens were collected from Vietnam in September.
GenBank accession no
Binh et al. V6038: LC331259 (rbcL), LC331256 (matK).
Preliminary conservation status
Quercus bella was only previously known as an endemic species to China and distributed in Guangdong, Guangxi and Hainan. The species is not recorded as a threatened species in IUCN (2017)[2]. 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[3]) and Vietnam Red Data book (Ban et al. 2007[4]).
