Opinion Piece for Sydney Morning Herald: Pest Mismanagement in Sydney's Parks

Brumbies are known as the feral horses that inhabit Australia- mostly throughout the Northern Territory, Queensland and scattered centrally in Western Australia. Some small mobs live within Victoria and New South Wales, but none as vast or dense in population. These horses influence the natural habitat in many ways- they reduce vegetation growth, cause soil erosion and impact upon other animals living within the ecosystem. They are seen as pests to national parks, and essentially, this is the reason for their culling- they cause more damage than they are worth. The only positive aspect a brumby herd will impose is that they maintain walking and driving tracks throughout state parks.

An ecosystem contain biological communities and abiotic factors that interact with each other. However, Introduced pest species in Australia have always been a major issue due to the unique ecosystems that have developed, undisturbed over millions of years, due to Australia's geographical isolation. This is especially evident in the introduction the European red fox in Australia, which has prompt negative changes to the population of the Long-nosed Bandicoot due to the predation by these foxes in the Field of mars and around Australia. The disruption the fox foxes have on the Long-nosed bandicoot can also result in sever cascading effects on the rest of the ecosystem, including abiotic factors like the soil and biotic factors like other native flora and fauna

An invasive species is a species that comes out of its natural environment, and enters another. These animals are usually very bad for the ecosystem and may cause an unbalance. These animals usually come in with many competitive advantages and can easily dominate any competition. This will give them the ability to eat as much as they would like without being threatened in any way. This could possibly diminish many populations and end an entire ecosystem.

Invasive species are very common all over the world. Invasive species are an organism that lives in an ecosystem in which they don’t belong. Invasive species are not only dangerous to people, but also the ecosystem and must be removed.

There are many creative ways the of invasive species is being addressed and they are a problem. There are many different problems with invasive species. There might be problems with invasive species, but people are coming up with fun and different ways the problem can be addressed. Pythons, wild pigs, and red foxes are all a danger to different wild life. There will continually be more species even if everyone thinks they are gone, they will come back every time even if it is a different

Significance: The question of whether or not invasive species impact the environment is an important one. The answer affects everyone. In today’s world, we take the outdoors for granted. People don’t realize how much it does for us. It provides economical resources, areas to relax, and oxygen for us to breathe. Without these simple things our lives would change drastically. Life as we

An example of an invasive species is “Cane Toad.” The cane toad was supposed to get rid of sugar cane pest, but then it came a pest. It only has a few predators outside from where it lives.But when animals try to eat it a discharge of poison goes on it’s skin and the predator gets poisoned and dies in a few minutes.Also it has been released into out of zoos on purpose.The cane toad used to live in South America and mainland middle of America, now it has been moved to Oceania and the Caribbean also North Australia.What people do is they eat toad and make soup of their eggs but this ends up killing them.

The cane toads in Australia has become a national difficulty. The Australian government has been providing funds to help with catching and destroying these pests. Scientists have not been able to find any kind of way to biologically control these toads. According to the Australian Government, “Cane toads have an impact on Australian Government controlled lands, including Kakadu National Park, several World Heritage Areas and Indigenous Protected Areas”. The Australian government has written a policy on cane toads, has started a cane toad advisory group, funded research on controlling and collecting the toads, funded research on the impact of the toads on the Australian habitats and economy, and has educated the public about the toads and how to deal with them. In the future, the government plans to continue to do these same things as eradicating the toads does not seem feasible. All of these efforts are being made to at least reduce the threats to humans and native species in

Thus far, the advantages and adaptations discussed have been primarily of native Australian species. However, a specific advantage evident in non-native species is the way they insert themselves into the food web. Introduced species disrupt the balance of the food web in a variety of ways. One way is direct competition, directly increasing the pressure on other native species by competing for the same food supply. This is when survival of the fittest really comes into play.

Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood.  In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages.  In the Earth’s history, changes have often occurred in the ecosystems.  For example, glaciers and the retreat of glaciers cause wide-spread changes.  However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses.  Harm to the environment from the introduction of invasive species occurs through changes in the habitat and declines in the native species.  Invasive species

Although Australia would like to rid itself of this pest using various methods of removal, the effects could possibly become even more devastating to Australia’s wildlife. It has been found in recent studies that introduction of a new species, such as the European rabbit, can lead to native predators

Invasive species are everywhere and are as harmful as ever, with the new information this article brings to the table, it brings out a new strategy for elimination of them. There will have to be more improvements to the method to fit the case of individual species, such as how birds and fish can’t merely be tracked by a sniffer dog. Improvements are bound to come, as well as new possibilities and information on these species to keep them on a manageable or rather extinct level.The faster these things are gone, the better for us and the environment. It may just be some ants in Santa Cruz isle but hopefully, these kinds of methods could help put a stop to invasive species

For most of Earth’s history, ecosystems have existed in perfect balance. Some species survived, some did not, but environments as a whole functioned well. All of this changed, however, when humanity began mass migrations and invasive species began to interfere. “Invasive species,” writes James C. Russel, author of the report, Do Invasive Species Cause Damage? Yes. “are defined as the subset of nonnative species that cross a threshold for disproportionate negative impact in an ecosystem.” In short, they are plants, animals, fungi, or even bacteria that enter an ecosystem in which they are not native, and take over. Invasive flora have become a particular issue in recent years. The plant kingdom has always been a vicious one, with organisms

The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native species.

Invasive species are organisms that are not native to an ecosystem and cause harm to it. These organisms are capable of bringing about a great deal of damage to the ecosystems they are foreign to. This can range from disrupting the growth of the environment it has taken over to completely decimating other species. The introduction of invasive species to new environments often involves humans. The way that invasive species are introduced to a new environment varies greatly. Invasive species may be introduced by something as simple as humans accidentally tracking species into a new environment from the bottom of their shoes, or something bigger like destroying an ecosystem to clear the land, forcing the species that lived there to flee to a new ecosystem that can be disrupted by the presence of a new species.
