Invasive species pose a threat across the United States and its territories, but they can be especially challenging for the U.S. South Pacific territory of American Samoa. Among the invasive pests menacing the territory are several non-native fire ant species. 

The 2021 independent State of Environment Report has highlighted that invasive species are identified as the most prevalent threat to Australian wildlife and are the primary cause of extinction events. The report warns of the compounding and devastating impact of multiple threats to Australia’s environment, especially invasive species, habitat destruction and climate damage.

Invasive species are well known for their huge ecological costs, but they also bring a massive economic burden with sociological, environmental and health impacts. New research led by the University of Aberdeen and the University of Auckland in collaboration with CNRS, France has established that invasive species have cost the New Zealand economy almost $100 billion in the last 50 years. While damage costs remain high, this total includes spending far more than most other countries on pre and post-invasion management techniques relative to its GDP.

A new report, Fighting Plagues and Predators: Australia’s Path to a Pest and Weed-Free Future [PDF,  12 MB], reveals the environment is facing a "sliding doors" moment, with two possible futures for Australia, depending on the decisions made today. It highlights a looming wave of new extinctions and outlines two futures for Australia, one based on an unsustainable ‘business as usual’ approach and the other based on implementing targeted actions that will help save our unique biodiversity. The report pegs the conservative cost of damage caused by invasive species in Australia – predominantly weeds, feral cats, rabbits and fire ants – at $390 billion over the past six decades and around $25 billion each year and growing.

The U.S. Department of the Interior’s Office of Insular Affairs (OIA) has announced $2,772,443 in Coral Reef and Natural Resources Initiative (CRNR) grant funds to protect coral reef resources in the U.S. territories and the freely associated states. The funding includes $1,541,421 that will support efforts to control and eradicate invasive species in the insular areas. Grants for fiscal year 2021 to combat invasive species have been awarded as follows:

• University of Guam for research and related efforts to counter the Coconut Rhinoceros Beetle - $866,423
• Micronesia Conservation Trust, a regional non-governmental organization, for the eradication, control, and management of invasive species in Kosrae, Chuuk, and Yap - $300,000
• Island Conservation, a non-profit organization, for the removal of invasive rats in Mili Atoll, Marshall Islands - $299,838
• Commonwealth of the Northern Mariana Islands Government for Sabana Pandanus Forest control and native trees restoration project - $75,160

The Pacific Islands Marine Bioinvasions Alert Network (PacMAN) Project, which aims to monitor and identify marine biological invasive alien species, was officially inaugurated on November 24 in collaboration with the Institute of Applied Sciences at The University of the South Pacific (USP-IAS).

USP-IAS Acting Director, Dr Isoa Korovulavula stated it was a significant occasion as they moved collaboratively to a new "frontier" of protecting the local marine environment from invasive species. "The PacMAN Project is expected to boost local capability for early identification and warning of maritime invasive alien species. We are using revolutionary technology, such as DNA metabarcoding, to identify and deal with marine invasive alien species in our local marine environment," he explained.

New Zealand Parliamentary Commissioner for the Environment, Simon Upton, is calling for the Government to lift its game in protecting native ecosystems from the thousands of exotic plants spreading throughout Aotearoa New Zealand. “Rampaging weeds pose a deadly threat to our native ecosystems by smothering, outcompeting and preventing regeneration of native plants,” the Commissioner says in a report released today. The report, Space invaders: A review of how New Zealand manages weeds that threaten native ecosystems, explains that protecting our native ecosystems from being overrun by weeds not only helps our native taonga plants, but also saves crucial habitat our taonga fauna need to survive.

In May 2022, an outbreak of FMD was reported in cattle in Indonesia and has since spread to Bali. An incursion of the virus would have severe consequences for Australia’s animal health and trade. The emergence and rapid spread of FMD in Indonesia has changed the risk profile for passengers and goods arriving in Australia. As result Australia has strengthened its border activities and new measures were immediately imposed to help prevent an incursion.

We need your help to keep watch for the brown marmorated stink bug. The brown marmorated stink bug (BMSB) is an agricultural, horticultural, and social pest. It's native to Asia and has spread throughout North America and Europe. It isn’t established in New Zealand, but this sneaky pest hitchhikes on passengers and imported goods. We’ve caught them at our border many times. We need everyone’s help to keep an eye out for them.

If you think you’ve found a brown marmorated stink bug – don't kill it.

• Catch it.
• Take a photo

Predator Free 2050 is working towards an Aotearoa where our native species are safe from extinction and thrive alongside us – and everyone has a role to play in the movement.

Australia is lucky to be free from many of the world’s most damaging plant pests. Exotic plant pests are capable of damaging our natural environment, destroying our food production and agriculture industries, and some could change our way of life. Australia’s biosecurity system helps protect us from exotic plant pests. The Department of Agriculture, Water and the Environment manages this system with state and territory ​governments, industry and the community. The Plant Health Committee has recently reviewed the National Priority Plant Pests that are exotic to Australia, under eradication or have limited distribution. These are the focus of government investment and action, including funding through the Priority Pest and Disease Planning and Response. While by no means the only plant pests of biosecurity concern, the National Priority Plant Pests serve to highlight the sort of threats Australia faces. View the National Priority Plant Pests (2019).
