"The rhino population has grown, because in 2010 three rhinos were born," said Hendra Purnama, an evaluation and data officer at TNUK, on Monday.
Based on the recordings of 30 video traps, which were installed at several points at the national park in 2011, the rhino population is estimated to be at around 35 heads.
"We will increase the number of video traps to 60 units, and the probable population of rhino to 100 heads," Purnama said.
The reproduction of Javanese rhinos at the park is not facing any serious problem due to safe the habitat and ample vegetation.
"I think there is no problem concerning the rhino`s food because there are 114 kinds of leaves that they could eat," Purnama said.(*)
