Arthur's Pass campsite torn up by 4WD vehicles

The Department of Conservation (DOC) is appealing to the public for help after a popular campsite at Arthur's Pass in the South Island was torn up by 4WD vehicles.

The popular and picturesque Klondyke Corner Campsite draws thousands of visitors each year and was a key feature of the annual Coast to Coast multi-sport race.

Aerial photos illustrate the extend of damage which was believed to have happened on 1 August at about 4pm.

DOC operations manager Leeann Ellis said it was incredibly disappointing.

"The vehicles have left deep tyre tracks over a large area, compacting the soil, creating wide ruts and making the site much more susceptible to erosion in heavy rain," she said.

"They have also destroyed plants and opened the area up for weeds to grow and take over. Its ruined what was a fantastic place and created the potential for a muddy mess in heavy rain."

The department was working with police to try and identify the vehicles and said it welcomed any information from the public.

It was illegal to damage any national park's natural or historic features and to drive vehicles on off-formed roads.

Offenders can face heavy penalties, including infringement fines and prosecution.

Under the National Parks Act, interfering with or damaging a historic feature in a national park carried a maximum penalty for an individual of up to one year in prison, a $100,000 fine, or both.

"We appreciate four-wheel driving is an increasingly popular recreational activity," Ellis said.

"There are some fantastic tracks where drivers can challenge their skills and access some beautiful locations like the Edwards Valley and Maling Pass 4WD tracks in the St James Conservation Area. Our plea is don't go off road and cause damage to areas which are protected for a reason.

"Naturing is looking after the environment when you are out enjoying these special places."
