A rare Sumatran rhino called Rose has given birth to a female calf at the Sumatran Rhino Sanctuary in the Way Kambas National Park in Indonesia, in what is being considered a great success for the conservation efforts of the critically endangered species.

Indonesia's Ministry of Environment and Forestry said this was Rose’s ninth attempt, having previously miscarried eight times.

Sumatran rhinos are the smallest of all the rhino species and with fewer than 80 individuals left in the world they are one of the most endangered land mammals on the planet, according to the International Union for Conservation of Nature (IUCN).

Rosa’s gestation period lasted 476 days and the first time mother gave birth last Thursday, 24 March.

The calf’s father Andatu, was the first calf ever born at the Sumatran Rhino Sanctuary, the International Rhino Foundation said.
