JAKARTA, Nov 28 (NNN-ANTARA) – Indonesia released seven Javan langurs into the forest on Mount Biru, in Batu City, East Java, a conservation agency said.
The Aspinall Foundation Indonesia, said, the langurs consist of a male and six females.
Before being released, the langurs, aged between two and seven years old, have undergone a 1.5-year rehabilitation process.
The health test results concluded that, they were free from infectious diseases, such as tuberculosis (TB), hepatitis B, herpes, and others.
A transponder microchip has been attached to each of the langurs to monitor their condition.
Meanwhile, the release location, on Mount Biru, is a mountainous tropical rain forest area that has a variety of vegetation.
Javan langurs live in Indonesian forests on the western and southern coasts, such as those on the islands of Java, Bali and Lombok, where their population has decreased by more than 30 percent over the past 36 years.
Javan langurs are listed as vulnerable species on the International Union for Conservation of Nature (IUCN), Red List.
Since 2012 the East Java Natural Resources Conservation Agency and the Aspinall Foundation Indonesia, released 102 Javan langurs.– NNN-ANTARA
