The woolly rhinoceros, so named for the coat of hair it shares with the Sumatran rhinoceros, first appeared in China; by the Upper Pleistocene, it ranged across the Eurasian continent from Korea to Spain.

The Sumatran rhino is the most endangered of all rhinoceros species due to its rapid rate of decline. , The first documented Sumatran rhinoceros was shot 16 km (9.9 mi) outside Fort Marlborough, near the west coast of Sumatra, in 1793.  The name lasiotis is derived from the Greek for "hairy-ears".  Opponents of the captive breeding program argue that the losses are too great; the program is too expensive; removing rhinos from their habitat, even temporarily, alters their ecological role; and captive populations cannot match the rate of recovery seen in well-protected native habitats.

Recently, a calf was born in captivity of an endangered female in western Indonesia, only the fifth such birth in one and a quarter century. It inhabits hilly areas close to water, particularly steep upper valleys with copious undergrowth.  A Bayesian skyline plot of complete Mitochondrial genomes from multiple individuals from across the range of the species suggested that the population had been relatively stable with an effective population size of 40,000 individuals over the last 400,000 years, with a sharp decline starting around 25,000 years ago. , The Indonesian ministry of Environment, began an official counting of the Sumatran rhino in February 2019, planned to be completed in three years.
