What Makes An Invasive Species

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 make bad situations into worse situations. Having a species from a different ecosystem makes them invasive species. Such as a toad or even bacteria being in another ecosystem other than their natural habitat.

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.

Issue: The environmental issue that I have chosen is the impact that invasive species have on the environment. The impact that invasive species have on the environment is vast, yet little is done about it. This issue is extremely important and will impact the world for generations to come. In this paper, I hope to learn about the effect they have on environment and what we can do about it.

Invasive species don’t just cause monetary damage, they can completely disrupt and destroy ecosystems. Invasive predators like the brown tree snake can hunt native species to extinction because these species have not evolved defences against them. Even herbivores can cause indirect damage by feeding on the same plants as native herbivores therefore taking away their food sources. Plants can cause damage as well. Through various strategies they can take over the land where native plants would normally grow diminishing native plant populations. No matter what kind of creature an invasive species is it can still cause damage.

Invasive species are organisms that harm a new environment that they are not native to. Many invasive species like Eurasian milfoil are easily able to reproduce and can do so fast. Due to this, the limited space in a body of water or area of land is quickly taken over by the invasive species so other native plants face the risk of death or even extinction. Overall, these invasive species can do great harm to an ecosystem or an economy, causing problems that are destructive to numerous organisms.

Most of the time people bring non-native species into new environment by purpose. The people who bring them to their new environments mostly aren’t aware that they could harm their new surroundings. When trying to reverse the effects of an invasive species it could take years. It takes volunteers hours upon hours to dig up plants, trap, scare away, burn, poison, and animal proof areas to prevent an invasive species from spreading. Introducing a non-native species into a new environment is like introducing fire to

From the smallest fly to the blue whale, from a blade of grass to a towering redwood, everything exploits the natural resources that Earth and its other inhabitants provide. In order to ensure its survival, an organism must assimilate itself into the food web or risk extinction at the hand of natural selection. Sometimes, a species is accidentally or purposefully introduced into a new area. These newcomers, commonly known as invasive species have no choice but to make themselves a part of the food web or die out. Unfortunately, that usually leads to fierce competition for resources between a local species and the invasive one, in which only the victor is allowed to survive. In a relatively short amount of time, the sudden pressure on resources can completely upset and destroy an ecosystem, taking the invasive species with it. With the invasive species destroyed, the ecosystem can slowly rebuild back to the way it was before. According to National Geographic, an invasive species is a “type of plant or animal that is not indigenous to a particular area and causes economic or environmental harm.” (National Geographic).[6] Based on that definition, humans sound suspiciously like an invasive species, except on a global scale. If humanity does not decide to become more sustainable soon, we will suffer the same fate as other invasive species: extinction. Luckily, the pressures of human exploitation of the environment for resources can be mostly eliminated through the use of

Introduced species can also wreak havoc by being defensive predators themselves. They can bring toxins and poisons into the ecosystem that their prey and predators alike can’t combat. “The [cane] toads are toxic, and native predators have no immunity to the poison,” (Semmler, para. 5). This makes them a keystone species (a species that has an impact with a size that doesn’t correlate to its population size). They affect large amounts of the ecosystem and food web, even while not having as large a population as other species that are

At the Fort Snelling State park, there are several aquatic and terrestrial invasive species. We need to eliminate and reduce their reproduction as soon as possible. By the way, what do we mean by invasive species? They are plants and animals that are not native to Minnesota. Zebra mussels, new species of Silver Carp, and Eurasian Watermilfoil as typical examples of invasive species in the park, which make headache in Mississippi and Minnesota River. Until a stable balance is reached, healthy and balanced ecosystem keep this balance through several limiting factors, which can restrict and regulate the size or range of species such as natural climate, geography, presence or absence of predators. However, these invasive species are accidentally

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

An invasive species is a plant or animal that is introduced to specific location where the specie is not native to it; and has the ability to spread very quickly , which is believed to cause damage to the environment, human economy and/or human health. The term most used for this species is Introduced species (also called “non-native”), these species affect the habitats and environments they invade environmentally, economically and ecologically.

Invasive plants, and the effects they have on ecosystems, have attracted the attention of scientists and researchers around the globe. As one of the main drivers of alterations within our ecosystem, invasive plants have the capabilities to alter plant diversity, productivity, soil chemistry and nutrient cycling, as well as degrade habitats, and displace native species (Kuhman, Pearson, & Turner, 2011). Understanding the factors that allow these non-native plant species to invade new habitats will help further efforts to manage invasions and protect our native species.

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.
