The majority of Lord Howe Island has been closed to non-essential visitors due to the increased risk of myrtle rust, a disease-causing fungus.
The Lord Howe Island Board announced via social media that the Permanent Park Preserve, which covers about 70 per cent of the island and was created to preserve its native flora and fauna, is temporarily closed and cannot be accessed via recognised access points, bush tracks, or boat.
The popular tourist destination located in the Pacific is home to rare and threatened plants and animals, meaning authorities can take drastic measures to preserve the ecosystem.
“The rust has the potential to change the way our mountains and forest looks, it may alter food webs and ecology, and potentially affect world heritage values,” a board statement to residents said.
