Conservation efforts are crucial for the survival of the critically endangered Sumatran Tiger, which is indigenous to the Indonesian island of Sumatra and has a wild population of only about 400 individuals.
Unfortunately, the black and white rhino populations have declined drastically over the past few decades, with the white rhino being listed as Near Threatened and the black rhino being listed as Critically Endangered
Both species have experienced significant declines due to poaching. Finally, some populations are showing signs of recovery thanks to conservation efforts.
