Many factors have contributed to the decline of the tamaraw population. Over the course of the century, the increase of the human population on Mindoro has exposed the island's sole tamaraw population to severe anthropogenic pressures. In the 1930s, the introduction of non-native cattle on the island caused a severe rinderpest epidemic among the tamaraw population then numbering in the thousands. Hunting of tamaraws for food and sustenance has also taken a toll on the species' numbers. The most major factor threatening survival of "B. mindorensis" is habitat loss due to infrastructure development, logging, and agriculture. These factors reduced the population of thousands during the early 1900s to less than 300 individuals in 2007.
