Nguyen Vu Linh, the park’s director, said targeted monitoring in 2025 documented at least 29 wildlife species across 10 sites.
These included three critically endangered species, the Truong Son muntjac, Owston’s civet and pangolin, alongside two endangered species, the red-shanked douc langur and serow, and five classified as near threatened under Vietnam’s 2024 Red Data Book.
The masked palm civet, a rare species, is listed in Vietnam’s Red Data Book.
The serow, a large ungulate of the bovine family, is found across several Vietnamese provinces, including Son La, Cao Bang, Lai Chau, Lang Son, Phu Tho, Quang Ninh, Haiphong, Thanh Hoa, Nghe An, Ha Tinh, Quang Tri, Hue, Danang, Gia Lai, Dak Lak and Lam Dong.
The red-shanked douc langur, a species at Bach Ma National Park, is rapidly declining due to hunting and habitat loss.

Other species recorded included red-faced and pig-tailed macaques, porcupines and various small carnivores, with some showing increased presence, notably the Truong Son muntjac.
The crested porcupine, also known as the hairy pig, is widely distributed across forest types from north to south Vietnam at elevations below 2,000 metres.
Spanning more than 37,400 hectares across Hue and Danang, the park is home to 1,728 animal species, including dozens listed in Vietnam’s Red Book and by the International Union for Conservation of Nature.
Established in 1991, Bach Ma was designated an ASEAN Heritage Park at a regional conference in Quang Ninh in December 2025.
