Bulbophyllum atrosanguineum

A major threat to biodiversity in the Van Ban area is habitat degradation as a result of selective extraction of timber species, notably Fokienia hodginsii. The government of Viet Nam passed a ruling permitting the extraction of over 20,000 m² of F. hodginsii timber from the Hoang Lien mountains. Although this decision specifies that only dead F. hodginsii may be harvested, in reality, effective enforcement of this condition will undoubtedly prove to be impossible. This decision represents a potentially serious threat to areas of primary forest that have hitherto only been subjected to small-scale timber extraction by local people.

Other major threats include habitat loss, through clearance of forest for agriculture and associated forest fires.

Described as 'rare', that is 'low risk', according to 1994 IUCN Red List categories (Averynov and Averynov 2003). The specimen location is in the region of the Hoang Lien Mountains which were the subject of a Darwin Initiative project in 2002-2003 and is designated as one of the last refuges of the western black crested gibbon. Hoang Lien-Van Ban Nature Reserve was established in February 2007 (Dat 2009). The type specimen is reported to be close to, but not within the boundaries of this reserve.

While orchid-specific conservation measures were not apparent, the efforts to protect the Critically Endangered (CR) Western Black Crested Gibbon should afford some protection for orchids.
