Invasive species are a key threat to Australia’s biodiversity. They are damaging to Australia’s unique ecosystems, as well as to the agriculture sector. The highest-risk exotic invasive species have been identified and compiled into the Australia’s Exotic Environmental Pest List (EEPL).
The Exotic Environmental Pest List
Exotic environmental pests, diseases and weeds are those not established in Australia. If these species become established, they could cause significant damage to our environment including our unique native plants, animals and First Nations heritage sites.
In November 2020, the department released the National Priority List of Exotic Environmental Pests, Weeds and Diseases. This is also called the Exotic Environmental Pest List. The list contains 168 exotic species, categorised into 8 biological groups.
- Aquatic animal diseases
- Freshwater invertebrates
- Marine pests
- Native animal diseases (wildlife diseases)
- Plant diseases
- Terrestrial invertebrates
- Vertebrates
- Weeds and freshwater algae
Higher Risk Exotic Environmental Pests
Each biological group on the EEPL contains 17-24 entries. Each entry is either a single species, a genus, or a small set of closely related species. The 5-6 entries in each group with the highest biosecurity risk are included in a list of 42 species called the ‘higher-risk EEPL’.
