What Are Invasive Species

Invasive Species Invasive, alien species, those which colonise, expand and out compete native species (Smith & Smith, 2009), are a major threat to our habitats, terrestrial and aquatic species, and biodiversity. Agricultural and leisure industries are affected as well as conservation welfare and the continued wellbeing of man, flora and fauna. Whole ecosystems can be distorted and the economic cost of awareness, prevention and eradication systems is substantial. Most invasive species have been introduced by mandeliberately or otherwise. As an island, Ireland has been subjected to less invasive species than larger nearby land masses e.g. Europe, but islands have a less diverse species population and are therefore more vulnerable when invaded.

People will not take good care of them because they get to big and their owners get scared and release them into the wild where there is already other animals habitats without thinking there is other ways you can get rid of your invasive pet. The second reason is, Certain plant rely on animals to keep them alive in their environment in which they live in. If you take the animal away from its original environment it could affect plants that rely on that animal and could cause the animal that went to its new environment to cause it to scare an animal away that had a plant that relied on that animal. or the new animal could eat the plant that the other animal relied on. My third and final reason is, The invasive species multiply and take over the environment causing corruption and harm.

An example of a species that has undergone a change due to an environmental alteration, is the Brush Tail Possum (Trichosurus vulpecular). The Brush Tail Possum is native to Australia and was introduced into New Zealand in the 19th century for the purpose of gathering fur for the fur industry. However, the species thrived in this environment and is now considered an agricultural pest. The possum can also carry a disease called

Depending on the different environment that a species is introduced to, the species’ characteristics will determine whether or not it will be invasive, helpful, or just a non-native species. An invasive species is a species that is introduced to a new environment, either on purpose, or by accident, and causes harm to our environment, economy, and health (Ballaro and Morley 1). A non-native species is a species that lives outside of its natural habitat, but does not negatively impact its new environment. A native species is a species that has thrived in a region for thousands of years without being accidentally, or intentionally introduced (Ballaro and Morley 1).

When a certain species is removed from their ecosystem, it can have effects on their prey and their predators. Their prey’s population would increase, and their predator’s population would decrease due to their being nothing for it to eat.

Topic:They mess up the wild life. Name:Mandi Powell Having exotic animals in the wild is very bad. The animals will mess up other homes for the other animals, kill other animals, and destroy the food for the other creatures. Destroying wildlife is a horrible thing the snakes killing the mice, the alligators eating the fish in the lake, and the lion eating the zebras. Exotic animals destroy our wildlife by messing up the trees, our ground, and the lakes and ponds.

Invasive weeds and grasses could crowd out native plants and shrubs, accelerating erosion and leading to more frequent

Poaching and illegal hunting can cause an off set in the ecosystem by overhunting animals. When one animal population decline drastically, other organisms are affected too. The decline in native predators is the main cause for overpopulation of animals like deer. Deer overpopulation has led to rapid decrease vegetation life causing other animals to be put at risk. Removing predators from the food web disrupts the entire balance of an

These include Haitian solenodon the Hispaniola Hutia who have both been thrown to the verge of extinction. Haiti is one of the only places where you can find them in the wild. There have been other animals that have been brought to extinction and unfortunately didn't make it. There are many different flora in Haiti, like the giant tree fern, orchids and bayahondes it is very life filled. Many people go to Haiti to see all of the wildlife and flora that can be found in only a few other spots in the world.

Because of this, many native species are dying out.

All living species should be treated with care and respect, no organisms should be made a commodity for the sake of human interest. Exotic animals, which are unusual or rare species such as lions, tigers, and non-human primates – are nowadays kept within households as pets. However, according to research, 98% of the people believe that exotic animals should not be kept as “pets”. Such opinions are due to several reasons that are sometimes supported and other times opposed. Exotic animals should not be treated as pets because they are not completely tamable, they belong to their natural habitat, and they may be transmitting zoonotic diseases to those around them. In contrast, some people believe that exotic animals should be kept as pets to save them from extinction.

They expand rapidly and spread quickly over wide areas, and out-compete or prey on native species. While all invasive species are non-native species, not all non-native species are invasive unless they meet these guidelines. If they are useful and not harmful to the ecosystem, the non-native species will not be considered invasive. 66. In a survey of a stream bank in northeastern Ontario, a local naturalist group found that 20% of the plant cover was made up of purple loosestrife.

Frogs and koalas have been endangered for a long time. Like some reasons of why they are endangered is that people have been destroying their homes. Like frogs have been living in the water but humans dig up the dirt right next to the dirt and koalas humans have been cutting down the trees to make houses for themselves and not keep the koalas home their. Frogs have been dying because people destroy their homes and take all of their food so they can’t survive. Also with why more people in the world they can live in the rain forest where the frogs live and with the koalas the people take the homes by cutting down trees and not growing new ones for the

This usually causes extinction within that species, and researchers have decided to do something about it. Although endangered animals are born in the wild, they should be sheltered and protected in nature parks because it helps decrease the amount of extinctions, allows a better and healthier environment, and the animals are protected from predators and human hunters. Endangered animals are to be kept in zoos because it decreases the amount of extinctions. Human activities have affected animals living in the wild dramatically throughout history.
