animals
  The introduction of exotic aquatic animals and aquarium plants into waterways within the park would pose significant ecological risks. Exotic marine animals such as the black-striped mussel could pose significant threats to coastal and estuary areas, and introduction of exotic aquatic snails and fish, such as Tilapia, would have serious impacts on populations of native freshwater species.

    * Exotic birds
  Residents and visitors are not allowed to bring in pet birds, as they may introduce diseases and some species may become pests. Eradication of exotic birds is difficult if large populations become established over significant areas. Species accidentally introduced into Darwin, such as tree sparrows and spice finches, could become a problem in Kakadu if they became established more broadly in the Top End.

    * European bees
  European bees may adversely affect native insects and compete with native animals for nectar, pollen and tree hollows. Research is required to determine the abundance and level of impacts of European bees on wildlife within the park. Control by park staff does not presently extend beyond park infrastructure and visitor areas.

Management issues

    * High-priority species
  Pigs, buffalo, feral cats and cane toads have a very significant impact on threatened species and other biodiversity in the park. Pigs and buffalo have a significant impact on yams and cultural heritage sites. Wild dogs and black rats are also likely to be having a significant impact on fauna species.

    * Potential new species
  Yellow crazy ants, mosquito fish and other aquarium and introduced fish such as Tilapia represent a high potential threat to park values. Some introduced bird species could also become pests or transmit disease to wild populations. Preventing introductions of new species is the most important option available for reducing risk of further damage caused by feral animals. Rules regarding restrictions on what animals may be brought into the park are not always followed, either intentionally or accidentally, through lack of knowledge. It is important to provide residents with good information about the potential impacts of introduced animals prior to their arrival in the park.

    * Unattended pets
  Domestic dogs are often left unattended on outstations when people relocate either temporarily or permanently. The dogs are left to fend for themselves; they scavenge for food and may interbreed with dingoes and become a public safety risk especially around residential areas. Similarly cats introduced to outstations are likely to have contributed to the feral cat population. Following two successful desexing programs in 2014, over 90% of the dogs and cats in the Kakadu outstations are now desexed. This means that unless there is recruitment of animals from outside the park, the dog population will progressively reduce. Having a reduced dog and cat population
