Kakadu National Park By: Kevin Ng
BackgroundInformation • Kakadu is how you say it but it’s a mistake of Gaagudju, a language spoken by the northern part of the aboriginal tribe in the park that something you can teach to your friends! • Kakadu National park is situated 171km southeast of Darwin, Northern Territory, Australia. • Over 200km it extends from north to south and over 100km from east to west, covering an area of 19,804 square km. • The most productive uranium mines in the world is separate from the park but surrounded! • Kakadu National park is the size of Slovenia! And what makes it even more fascinating is that’s it’s half the size of Switzerland. But it doesn't stop their it even one third the size of Tasmania!
Native flora andFauna • There are over 1700 native flora species in Kakadu National park. • Areas where there is water are populated with a variety of mangroves which are important for the living of coastline species such as fish. • Native flora helps to preserve the park as they are kept in protective conditions and nourish the park by the blooming of the different kinds of the plants. • There are about 74 species of mammals, 280 species of birds, 117 species of reptiles, 25 species of frogs, 10,000 species of insects and 32 species found to be fish. • Fauna are kept in captivity around the park where people are not doing any harm, this helps preserve the national park and nourish it by providing other at-risk species to fulfil their function.
And Plants • Introduced species are species which are living outside their normal environment which are arrived by humans for recreational activities, by accident or deliberate. • It kind of like you taking someone's seat, wouldn’t that be annoying? • Introduced species are not all badbut can have a both negative or positive effect on the surrounding environment. • Species which cause widespread damage and problems are known also as invasive species. • If a introduced species is damaging it can be a threat to the native biodiversity of an area. • These introduced species which are damaging (invasive species) can spread diseases that can be detrimental . • Australia has 56 introduced invasive species.
Damaging of Kakadu National park due to Introduced species. • Kakadu National park has seen many invasive species such as cane toads, water buffalos, wild pigs and weeds like the Mimosa Pigra that have threatened the native environment in the past recent decades. • Asian water buffalos were introduced between 1820s and 1840s for meat and hide, and since they have increased in population destroying plant growth which leads to the breaking down of soil. These buffalos also cause extensive coastal damage to the aquatic species like native fish as they have a muddy river bank habitat. • The invasive weed Mimosa Pigra covers 800 square km of vast areas of Kakadu which causes less land for native grass or plants to grow on Kakadu such as the spear grass.
Protecting Kakadu National park from introduced species • Many government plans have been used to protect native species from introduced species, one way to protect native plants from weed is: • A control spray which keep the weed from increasing throughout the year. • CSIRO have been monitoring the growth of weeds. • Low-impact chemicals are used to treat weed from further spreading. • In introduced animals there have been many plans to keep introduced species in control such as a campaign which caused many buffalos to die due to worries of a disease coming. • Park staff have carefully monitoring and controlling buffalo numbers and since then many areas have recovered.
Possible solutions to overcome the problem • There are many ways to help in protecting the native species from introduced species, even you can do it yourself, here are five ways you can help: • Many fruits, vegetables, plants and insects can become bad for the environment or carry pest. • Don’t release any animals or plants, or any weird plants into the environment. If you do have a exotic/weird plant do some research • Help at the park, as you can get more experience and learn more! • Clean your boots before you hike in a new area to remove any seeds or viruses. • When boating clean your boat before moving it to a different water area. • Kakadu park itself can also help itself by doing research and finding out how to overcome the problems and what works.
Thank You Thank you for listening to this presentation (..)public school I hope you enjoyed this and learnt something new about protecting the environment around you
