At least one species of rhinoceros is already extinct. The western black rhinoceros (Diceros bicornis longipes) was a subspecies of black rhinoceros that was native to parts of central and western Africa. It was declared extinct in 2011, after the last known individual was killed by poachers.

There are also several other species and subspecies of rhinoceros that are critically endangered and at risk of extinction. These include the northern white rhinoceros (Ceratotherium simum cottoni), which has only two individuals remaining, and the Javan rhinoceros (Rhinoceros sondaicus), which has a population of fewer than 70 individuals.

There are several conservation efforts being undertaken to protect and preserve rhinoceros populations. Rhinoceros are a group of large, herbivorous mammals that are found in various parts of the world, including Africa, Asia, and South America. All five species of rhinoceros are threatened by habitat loss, poaching, and other human activities.

One approach to rhinoceros conservation is habitat protection. This includes creating protected areas such as national parks and reserves, and working with local communities to ensure that these areas are not threatened by activities such as logging, agriculture, and mining.

Another important aspect of rhinoceros conservation is monitoring and research. By studying the rhinoceroses and their habitats, conservationists can better understand their needs and behaviors, and develop strategies to protect them.

Education and outreach programs are also an important part of rhinoceros conservation. By raising awareness about the importance of these animals and the threats they face, conservationists can encourage people to support conservation efforts and make more informed decisions about how to protect these animals.

In addition to these efforts, conservationists are also working to combat poaching and the illegal trade in rhinoceros horns. This includes efforts to enforce laws and regulations, as well as efforts to reduce demand for rhinoceros horns through education and awareness campaigns.

Overall, the goal of rhinoceros conservation efforts is to ensure that these animals have a healthy and sustainable future in the wild.
