What Are Invasive Species?

The invasive species are harmful for native systems and time and money should be invested to prevent these species from spreading and damaging systems that they are not native to. Strict rules for environmental obedience are necessary and good. Much more needs to be done to protect our planets and its biodiversity from the invasion of alien species. When non-native species from other ecosystems are introduced, they can upset that balance and bring harm to the established plants and animals, and the whole ecosystem. Non-native species come from somewhere else and they are not natural to the ecosystem they have been introduced to. They may be harmless and beneficial in their natural surroundings, but they can totally devastate

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

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.

Species have been invading the Great Lakes for a very long time. “Scientists estimate that there are more than 185 invasive species in the Great Lakes today.” One of the species that invade the Great Lakes is the Round Goby. This animal usually feeds on fish eggs, Yellow Perch, Bass, and Walleye. The Round Goby is an invasive species because it kills other species, or it can make them extinct. Another example of invasive specie is Quagga Mussel. The Quagga Mussel usually sits in lakes or oceans, building up over a long period of time, this leads to millions, and millions

Invasive species have been brought into the United States, some on purpose to help fill a needed use and then latter getting out of control and creating a mess of what they have done to waterways,

There is a huge and beautiful state park in the center of the Twin Cities in Minnesota as Northern United States of America, which is called “Fort Snelling State Park”. The park is the place of coexistence between nature and human resources. There are not only wildlife animals such as Turkeys, white-tailed deer, fox snake, and coyotes, but also there are a lot of human resources like biking trails, fishing, camping, and lodging for visitors to stay with eco-friendly and be in harmony with nature in the center of big city. At the Fort Snelling State park, there are several terrestrial and aquatic invasive species. What do we mean by aquatic invasive species? They are plants and animals that live in the water and are not native to Minnesota.

Alien species on the humber watersheds are a major ecological issue for the environment because they prevent other native species from living/growing in their natural habitat. Alien species do this by taking up physical space that native species need , preventing native species from reaching their food and water and spreading disease. The humber watershed is affected in two different ways: native species and the overall ecosystem of the watershed. invasive species on the humber watersheds have a major threat to the biodiversity of our waters,wetlands, and marshes. These organisms that originate from different ecosystems pose a great threat to our ecosystem because coming to our ecosystem their natural predators can no longer keep the population's growth rate under control and that causes an increase in population because of that devastating effects on native species, habitats, and ecosystems may occur. There are reports that over 185 non indigenous species were found Ontario’s Great lakes. Some invading species that been found in the Great lakes are the following;

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

Have you ever seen lake that is crystal clear with a bottom that is covered in muscles or has carp splashing on the surface as far as the eye can see? This happens when invasive species enter lakes and have an enormous population spike due to a lack of natural predators. In the video Aquatic Invaders it is said that “Over the last century and a half, there have been over 140 species that are invading the great lakes but, in only the last 30 years this trend has been accelerating (Donahue).”There are a wide variety of invasive species from hundreds of types of algae to big head carp and all of which have few positives and a large variety of negative effects. Despite the negative effects, there are few prevention methods in place to prevent these invasive species from entering our local water including the great lakes. While I do concede that there are a few positive aspects such as Bow fishing, I still insist that invasive species destroy lakes, kill native species, and could cost the state millions in lost tourism and fishery revenue.

There is one more aquatic invasive species. Have you ever seen the aquatic invasive species on the lake? This is Eurasian Watermilfoil, which are also found at Fort Snelling State Park. It was suddenly introduced to North America from Europe. The main reason why Eurasian can rapidly reproduce is that a single segment of stem and leaves can take root and form a new colony through stem fragmentation and runners. / Reproducing from lake to lake creates numerous amounts of new stem fragments while they cling to boats and trailers. / There are biological control and Invasive species program, which is to curb the spread the growth of Eurasian Watermilfoil. Using minimum of herbicides and imposing mechanical removal are to reduce them, but there is

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

A steward is someone who manages someone else’s property, possessions, or financial affairs. We have the responsibility to be good stewards of God’s earth. All creation has a place and an order made by God, and we should keep it that way. This includes keeping invasive and exotic species from causing other species to go extinct. As a Christian, one of the easiest things I can do to help stop the spread of invasive species is pray. I can pray for the people that are figuring out ways to stop it. I can pray that others would help in the fight against invasive species. And I most definitely can pray that the invasive species would just stop spreading. As Christians, God told us to rule over every living creature. That means that it’s our job to

Invasive species can take advantage of new areas because there is a lack of predators or parasites to

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

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.
