  1. Kakadu National Park Local Animals vs. Introduced Species

  2. Background on Kakadu National Park • Kakadu National Park gained its World Heritage Listing in 1984. Kakadu is one of the few Heritage Listed Areas that is listed for both cultural and natural heritage. The National Park is located in the Northern Territory about 252 kilometres east or Darwin and covers a total area of 19,000 square kilometres. The National wide diverse range of flora and fauna.

  3. Native Flora and how it helps preserve the national park • Kakadu has over 1700 plant species that are recorded. • Only 5.7% of the National Park contains weeds. • Mangroves are common along the coastlines as many fish feed of it and is home to many animals.

  4. Native Fauna and how it helps preserve the national park • Kakadu National Park is home to 68 mammals, more than 120 reptiles, 26 frogs, over 300 tidal and fresh water fish, and over 10000 species of insects. • Native animals have made habitats through out Kakadu National Park and have adapted to the environment and climate.

  5. Analysis of Introduced Species • Introduced species are also known as Invasive species. They are a serious threat to the native animals and native plants in Australia. • Invasive diseases, fungi, and parasites have a huge affect on the Australian native plants as they spread quickly and take over anything that’s in its way. This is the main reason why the native plants are decreasing in numbers. • Australia has around 56 introduced animal species. Most of these species breed very quickly and have spread all over Australia. E.g. cats, rabbits, mice and rats.

  6. Government initiatives to help overcome the problems of introduced species • The Government is paying too much money on these introduced species because the are damaging some agricultural industries and stock losses are severe in some cases. • There are two ways that the Government helps control introduced species. These are; conventional and biological control. • Conventional Control techniques of invasive animals include fencing, trapping, poisoning and shooting. These are more easier ways of getting rid of these feral animals. • Biological Control techniques is a way of controlling pests naturally by predators, parasites, disease- carrying bacteria or viruses.

  7. How have introduced species ( Fauna) damaged the National Park • The introduced animals that are found in Kakadu are; Asian water buffalo, pigs, cattle, donkeys, horses, cats, dogs, mice, rats, European bees, cane toads and house geckos. • Asian water buffalos have damaged many native plantsand other grasses. • Pigs have damaged habitats, dug up the grounds and have spread the weed mimosa across the park. • Cane toads are one of the biggest problems as they are very poisonous and kill animals that eat them. • Horses spread weeds and damage the waterholes.

  8. How have introduced species (Flora) damaged the National Park • The weed mimosa is one of the main introduced species of plants that have had a huge affect on Kakadu National Park. • There are also some like salvinia and Para grass which is also under the control because they have spread over large areas. Others are; mission grass, gamba grass, candle bush, calopo, Gambia pea, golden shower, Poinciana and coffee bush • Pigs and Asian water buffalos are one of the main reasons why this weed mimosa has spread so quickly across the National Park. • This weed competes with the native plants for light, moisture and nutrients. • This weed has been under control for the past couple of years and is still the main priority.

  9. List possible solutions to assist Kakadu National Park overcome this problem • The feral animals should be hunted and shot, removed form that area or trapped/ fenced. • Weeds should be controlled by pulling out or using herbicides to kill them. • With using these solutions, it is possible that the introduced species can be removed and Kakadu National Park can over come this problem.
