Deprived of their homes due to deforestation, their population has dropped to less than half...
The Baird's Tapir is losing its home as people cut down the trees in the forests where it lives. Deforestation changes the shape of ponds and swamps, rendering water bodies that were once safe unsafe.

The number of Baird's Tapir is said to have diminished to less than half over the last 30 years.
