Nepal's tiger population protected by troops and cameras

Nepal's Chitwan National Park has become the first site to be accredited with Conservation Assured Tiger Standards for its success in conserving and protecting its population of big cats.

The National Park is home to around 120 Royal Bengal tigers and also has the world's second largest concentration of single-horned rhinos.

Poaching has come down dramatically over the years thanks to the efforts by the Nepalese government and the army, with hundreds of soldiers patrolling the park to protect the animals.

Park officials constantly monitor the wildlife by using various methods including camera trapping.

The automatic cameras installed in hundreds of places deep inside the jungle take pictures of animals, helping them to estimate population numbers.

The BBC's Anbarasan Ethirajan joined Chitwan National Park officials to see tiger conservation efforts.
