  • Invasive Species: An Invasive Species

    What is an invasive species? According to the National Invasive Species Management Plan, an invasive species is defined as “a species that is non-native to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm or harm to human health”. Invasive species will look like they belong in the environment they are taking over, however, more than likely they are over-powering a native species in their own habitat. Would you be able to identify one of the species I’m about to discuss? North America has more than twenty-nine hundred invasive species in our environment today. I will begin by describing 2 invasive plants and then 2 invasive animals that are invading our natural species. First we have the invasive grass called “Cheatgrass”, which is scientifically known as Bromus Tectorum L. Cheatgrass was introduced into the United States through packing materials, ship ballasts, and possibly contaminated crop seed. This invasive plant is becoming widespread in the western U.S. in the higher and northern landscapes. As Cheatgrass invades ecosystems of natural communities it destroys and completely alters the site by eliminating the native grasses possibly due to fire or grazing. This plant is highly flammable and once it has taken over an area it becomes a high fire concern. Scientific research has been done to find a cost effective way to control the spread of this invasive grass. (Rimer & Evans, 2006) Another invasive plant…

  • Invasive Species And Invasive Species

    Invasive species, also called nature’s invaders, are a species that is not native to the environment it now lives in and is harmful to the ecosystem of that environment. They can be there due to a natural phenomenon, such as a flood, but more likely they were brought there by humans. Therefore, humans play a huge role in creating and controlling invasive species. An invasive species is able to cause the extinction of the native plants and animals, they multiply quickly and take a lot of the…

  • The Pros And Cons Of Invasive Species

    the environment. The transportation and the construction of facilities have introduced different kinds of invasive species in Seattle. Moreover, the illegal waste dumping and lack of maintenance also help spreading the invasive species. The common invasive species in Seattle are English Ivy, Himalaya Blackberry, American Bull Frog and fox squirrel, etc. The invasive species usually compete and edge out the native species. After a period of time, a dead zone will be created, only the invasive…

  • Negative Effects Of Invasive Species

    An invasive species is an organism that is not native and has negative effects on an economy, environment and health of an individual. Moreover, an invasive species can be a plant, animal or other organisms that might create negative impacts to the society. Furthermore, the definition can further be enumerated as a species that is non-native to the ecosystem under consideration and whose introduction creates results that are inefficient to those surrounding it. The impacts that are often created…

  • The Importance Of Invasive Species

    The loss of biodiversity is a direct reflection of the actions of the human race. Non-native invasive species, plants and animals alike are causing a drastic shift in the ecosystem and while these foreign aliens thrive they are consequently killing native species in the surrounding areas. While humans take most of the blame, other factors such as weather also play a role in the relocation of certain species; the natural occurrence of relocation is why it is crucial that the human race stop…

  • Causes Of Invasive Species

    Invasive Species “Invasive species are one of the leading threats to native wildlife and approximately 42% of threatened or endangered species are at risk primarily due to invasive species” (National Wildlife Federation, 2016, p.1). 1. What kinds of problems can invasive species cause? Do you think one group of invasive species is worse than another? Why, or why not? Some of the problems that invasive species cause is impacting natural ecosystems, the economy, recreational, agricultural,…

  • Invasive Species Project

    INTRODUCTION Background Invasive species are defined as non-native species that invade ecosystems and propagate to a point where harm is induced on native species. Types and abundance of harm caused to native ecosystems can vary greatly depending on various biotic and abiotic factors. Although the amount of accredited research devoted to aquatic invasive species (AIS) doesn’t reach far beyond the past few decades, the natural history of invasive species surely does (Pysek, 2010). A great deal…

  • Effects Of Invasive Species

    Non-native invasive species have caused conservationists and ecologists to stew. In simpler terms a non-native species is a species that is an alien to an environment, but will not cause danger. Invasive species are species that causes harm. More specifically, a non-native invasive species are a particular type of species that are foreign to an environment and causes risk towards that particular environment. Non-native invasive species, invasive species and NNS will be used interchangeably.…

  • Invasive Species Effects

    Invasive species are easily comparable to the explorers of the old days. Explorers could be helpful by introducing new supplies, like horses, during the big Columbian Exchange. Explorers could also be largely negative, bringing disease and slavery into the nations they conquered. Explorers sometimes just set up trade relations and left well enough alone. Much like these explorers, invasive species have the propensity to help, hurt, or assimilate into their new surroundings. Experts on invasive…

  • The Importance Of Invasive Plant Species

    Invasive plant species pose a tremendous threat to natural resources throughout the United States. Invasive species can choke out acres of native vegetation and greatly reduce wildlife habitat. Invasive plant species threaten every aspect of ecosystem health and productivity on public and private lands, threaten biological diversity by causing population declines of native species, and alter key ecosystem processes like hydrology, nitrogen fixation, and fire regimes. Preventing, managing, and…
