There are still major gaps in our knowledge about Javan rhinoceroses because they are extremely difficult to study and there’s a remote possibility that remnant, undiscovered populations exist.
There are still major gaps in our knowledge about Javan rhinos because they are extremely difficult to study.
Because of its rarity, little is known about the Javan rhinoceros’ preferred habitat and the species’ life characteristics and biology. The gestation period, inter-birth intervals, sexual maturity, longevity, and average lifespan is currently unknown and must be presumed based on information from closely related rhinoceros species, such as the Indian rhinoceros (Rhinoceros unicornis) or greater one-horned rhino.
As early as 1962, the World Wildlife Fund for Nature (WWF) pioneered scientific research on these rare animals. The organization is continuing to conduct important studies today, helping to reveal critical information on the rhino’s behavioral patterns, distribution, population size, sex ratio, and genetic diversity.
There is also a need to survey parts of the Javan rhinos historical range for the very remote possibility that small remnant populations exist, especially in parts of Laos or Cambodia.
