Sumatran serow

The Sumatran serow (Capricornis sumatraensis sumatraensis), also known as the southern serow, is a subspecies of the mainland serow native to mountain forests in the Thai-Malay Peninsula and on the Indonesian island of Sumatra. It was previously considered its own species, but is now grouped under the mainland serow (Capricornis sumatraensis), as all the mainland species of serow (Chinese, red and Himalayan) were previously considered subspecies of this species. The Sumatran serow is threatened due to habitat loss and hunting, leading to it being evaluated as vulnerable by the IUCN.

While legislation is in place in Indonesia to protect serow, meaningful penalties are seldom handed down and poaching and illegal trade continue. One study, analyzing seizure and prosecution data from Indonesia for the years 2014 to 2021, found a total of 13 seizure records, involving an estimated minimum of 32 mainland serow.
