'Terrible trade-off': Aussie filmmaker uncovers the desperate fight to save endangered rhinos

Each day dedicated rangers in South Africa's Balule Game Reserve put themselves in harms way to protect endangered rhinos from poachers.

Now, Australian filmmaker Paula Grusovin is taking their story from the grounds of the nature reserve to the world.

Four-part series The Reserve chronicles the challenges conservationists face in their bid to save the rhinoceros population, including dehorning the animals to reduce their value to poachers.

"It's a terrible trade off, but it keeps them alive and that's what counts," Balule head warden Ian Nowak said.

The Reserve is available on Stan.
