Invasive Species Advisory Committee: What Is An Invasive Species?

With the environment, as one of the most commonly discussed topics today, invasive species are often included in these discussions. However, many seem to participate in these conversations with limited background on the topic. It seems that non-native species are unfairly given the title of ‘invasive’ for a variety of reasons which I plan to explore. As a starting point, it is important to understand the various titles that are allocated to non-native species that have been introduced into a new ecosystem. Under the umbrella of non-native species, there are multiple classifications given to wildlife found in a region different from where the species originates. The broadest of these classifications is non-native or exotic. Non-native is very much a cut and dried description; the species is found in an area that it is not native to. Beyond non-native is established exotic. A species can be distinguished as established exotic if it is first considered a non-native species, then can establish a breeding population. In short, this means that the species must not only be new to an environment, but can then survive and succeed as a species in that environment. Last, there is invasive. To be considered an invasive species, the species must fit three criteria: one, the species is not native to the environment it is found in. Two, the species has been able to reproduce and has created a viable breeding population in the new environment. And finally, the species has begun to cause

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.

One environmental issue that the great lakes watershed has been exposed to is invasive species. An invasive species is any organism that is foreign to an ecosystem and causes harm (United States Environmental Protection Agency, 2016). In ordered to be classified as foreign they do not have to be from a different country but they just must be a non-native to an established ecosystem. Some of the species travel at their own will but they primarily spread through human activities unintentionally. As we import and export goods, or travel, some uninvited species may ride along and travel to new places. Organisms can be stowed away in ships or products like wood. Some ornamental plants may

The world is under attack; by aliens from our own planet. These aliens are known as invasive species. Government agencies such as the Environmental Protection Agency (EPA) and the Department of Natural Resources (DNR) have identified invasive species as living organisms that are not native to an ecosystem and their introduction can cause harm to the environment, infrastructure, and people. When these creatures are in their natural ecosystem they can be held in check by predators and other organisms that have evolved to deal with them. Without these opponents invasive species can and will cause economic and biological damage to the area they are introduced to. Invasive species can affect anyone and anything and they must

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

When someone introduces an non-native species into a new environment, it could harm its surroundings. Also known as an invasive species. The definition of an invasive species is “1) are not native to, yet can spread into, wildland ecosystems, and that

An invasive species is defined by Executive Order 122114. They are defined as an alien to the ecosystem, and the introduction of this species could cause or does cause economic or environmental damage or is harmful to humans (“What is an Invasive Species?” 1). It is also important to understand that it is not just animals that can be an invasive species (“What is an Invasive Species?” 1). Plants and microbes are also able to cause much harm (“What is an Invasive Species?” 1). Just how much harm do invasive species do though? Well it seems that these species are able to displace or eradicate native species, alter fire regimes, damage infrastructure, and threaten the livelihoods of people (“Invasive Species…..What are they and why are they a problem?” 1). In fact they are currently causing changes in

An invasive species is a plant, fungus, or animal species that is not native to a specific location and one point should be noticed is that invasive species does not have to come from another country. For example, lake trout are native to the Great Lakes, but are considered to be an invasive species in Yellowstone Lake because they compete with native cutthroat trout for habitat. Although there are some invasive species arrive with spread and establish populations, like the native butterflies feed on non-native plants in California, the alien trees help restore abandoned pastures to a condition suitable for native plants in Puerto Rico and even the much-maligned zebra mussel helps filter toxins from great lakes, most policymakers regard invasive

Certain invasive, human-introduced plants are definitely a problem, but some can provide a balance in the ecosystem by providing

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

Biological invasions are generally considered an environmental threat, out competing native species and increasing community homogenisation. Importantly though, invasive species also alter ecosystems, yet little research has focused on whether invasions are a threat to their functioning or services. This encompasses two main debates: determining whether invasive species alter ecosystem functioning and, if they do, whether these impacts are positive or negative. After reviewing current literature in an effort to resolve this controversy, it seems that in most cases, non-native species do alter ecosystem functioning. However, whether this change had

Invasive species can change the ecosystem; for that reason, is very important to agencies like the EPA, to keep close attention in the control,

An invasive species is a foreign organism that man introduces into a specific area. By being introduced, that means that man carries out these changes. Once relocated, the organisms continue to spread naturally (Díez-del-Molino, David, et al., 1). There is no such thing as a good invasive species, as any organism that is introduced to a foreign environment always takes away from a native species. This causes a decrease in the biodiversity of an ecosystem. Examples of invasive species include kudzu and fire ants.. Kudzu is swallowing North American plants. Forests are almost completely covered with kudzu, robbing the native species of an adequate amount of sunlight. Another example would be fire ants. Fire ants are native to South America and were accidentally introduced to other parts of the world, such as North America and Africa, during a soil transfer from South America to North America. In North America, fire ants are an invasive species because they overpopulate due to their advantage of having no natural predators. In Africa, fire ants severely hurt native ant, giraffe, and elephant species. They force the native ants to relocate due to the seizing and consumption of the acacia tree. This is also the reason for the harming of giraffes. Fire ants also tend to be pests to elephants and rhino alike, causing a parasitic relationship between the species. (Hartlieb

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.
