Braemar Station near Lake Pukaki at the base of Mt Cook is one of New Zealand's most picturesque locations.
Julia Mckenzie and her husband Hamish farm Braemar station.
Mrs McKenzie says the dryland area is more diverse and productive than is commonly believed.
However, the Lake Pukaki and the farmland itself are often put under severe environmental stress.
The bottom of the lake is terrible.
This can come from both heavy tourist flow and stock on the farm.
"Freedom campers have done a lot of damage driving vehicles over fragile land," Mrs McKenzie says.
"For us, it's about monitoring and making sure we're on top of any issues as they come up."
