Protecting our environment from pests and diseases
Biosecurity is the protection of our economy, environment and community from pests, diseases, weeds and contaminants. It keeps our World Heritage-listed island free from pest animals, plants and pathogens, and protects our rare native species and unique island ecosystem.
Who is responsible for biosecurity
The Department of Agriculture and Water Resources, along with other government agencies, industry, the island community, and visitors, all play a vital role in maintaining Lord Howe’s biosecurity.
How you can help
Under the Biosecurity Act 2015, everyone has a general biosecurity duty to prevent, eliminate or minimise any biosecurity risks they encounter. Most importantly:
- follow the Lord Howe Island importation guidelines for plant matter, animals, and freight; and
- report biosecurity risks such as rodent sightings and noxious weeds.
Our biosecurity rules
The Island’s biosecurity rules are different to those for NSW and the Australian mainland. Lord Howe has removed invasive mammals including cats, goats, and pigs. From 2019 to 2021 a rodent eradication program was undertaken on Lord Howe Island, the largest populated island to attempt a full scale rodent eradication. Comprehensive island wide checking of the permanent park preserve and settlement area is underway to determine the outcome of the eradication.
By eradicating invasive pests and preventing their reintroduction, we can protect the many species that are found nowhere else on earth and safeguard Lord Howe’s pristine environment.
General national biosecurity arrangements and responsibilities also apply. These are set out in the Biosecurity Act 2015 and subordinate legislation.
Invasive plant pathogens
Lord Howe Island is on alert for highly infectious plant pathogens like myrtle rust and phytophthora. These invasive diseases have the potential to cause irrevocable damage to our environment.
To avoid devastating impacts on Lord Howe’s ecosystem, please arrive clean and sanitise your hiking gear using sanitisation stations at all track heads on the island.
Management of myrtle rust incursions on the island has shown that early detection and community and visitor vigilance is key to successful treatment. Here’s what it takes to stop the spread of a serious biosecurity threat like myrtle rust in its tracks:
