JAKARTA, - Camera traps in an Indonesian park have captured images of 35 endangered Javan rhinos, five of them calves.

Forestry Ministry official Bambang Novianto said Thursday that dozens of video cameras were placed earlier this year in the Ujung Kulon park -- the animal's original habitat.

Researchers studying the images that came back were able to identify 35 different rhinos, though the total number in the park is likely higher.

The Javan rhino was once the most widespread of Asian rhinoceroses, but was nearly wiped out when the Krakatau volcano erupted in 1883, spawning a tsunami that inundated the park.

The greatest threat they face today is from poachers and habitat destruction.

Experts estimate only 40 to 60 Javan rhinos remain in the park.
