Channel Islands: The Colonization Of Invasive Species

Some examples of invasive species at Morialta Conservation Park include red foxes, weeds, blackberries, olive trees and many more. Foxes are responsible for the decline of small mammals, reptiles, and birds. One way to decrease the growth of invasive plants is to wear clean shoes. Morialta manages invasive species by putting up management signs at the information centre. I cannot think of any other way of managing invasive species.

The major negative effect of invasive plants is that they replace the native plants. Other negative effects of invasive plants are reducing native wildlife habitat, reducing forest health and productivity, altering the ecosystem, and degrading recreation areas. These plants should be removed immediately because they grow and reproduce rapidly, meaning, that they grow a lot faster than the native plants and more in abundance. They also affect the native plants by competing aggressively on resources. To resolve the problem invective plants is by removing them and adding more native plants. Also, another way to stop invective plants is by not planting them in new

My invasive species that I’m investigating is the American mink it is invasive in England. The American mink came from North America, and got brought to England in 1929 for fur farming.

The Channel Islands are located on the coast of Southern California in the Pacific Ocean between the cities Los Angeles and Santa Maria. Channel Islands National Park are made up of a chain of eight islands, Anacapa Island, San Miguel Island, Santa Cruz Island, Santa Rosa Island, San Clemente, San Nicolas, Santa Barbara, and Santa Catalina Island. In total, the park covers 249,561 acres. The islands are filled with a large variety of animals from land to aquatic. From the center of channel islands to the coast of Santa Barbara, it is approximately thirty miles, But it takes around two and a half hours to travel to the islands by boat. Opposed to the almost three-hour boat

The Maryland ecosystem is being ravaged by several invasive species. These species are introduced into the ecosystem in several ways, with several discoveries of invasive species every year. Whether it be Wavyleaf basketgrass or Purple loosestrife, these plants are capable of outcompeting with native plants and causing devastation to the native ecosystem. These invasive species are damaging to the environment and we should work as a community to halt the spread and limit its impact on the ecosystem of Maryland.

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

They are not native in that, at least for the case of the mustard plant, foreign missionaries brought the plants over to the United States, only for them to quickly and unexpectedly spread across the nation (Baker). Unfortunately, their spreading opens up a complication for estuarine preserves like in Newport Bay—it specifically affects the biodiversity in such areas. An article on the Newport Bay Conservancy’s official website defines biodiversity as “the sum total of species that occur naturally (native) in an area,” which also ties to “relationships and interactions [occuring] between these organisms” (“Invasive”). Even though the biodiversity of nature preserves is most known for being threatened by such matters as pollution and other similar human activities, the article is not afraid to point out that plants, specifically the non-natives, can also play a significant role in the issue (“Invasive”). Since plants like the mustard plant and Indian tobacco have managed to become widespread in the U.S., they can often end up as the dominant plants in their area. The main reason they are a threat to estuaries—or any nature preserve—is that if foreign plants end up truly dominating those which are native to the area, every organism that consumes the native plants will have a higher risk of being endangered as a consequence

Invasive species come in many forms; they can be plants, animals, insects, fish, fungus, organisms, and bacteria. Invasive plants are those which cause environmental, economic and human harm and originate from another area or region. They are a complex and difficult problem to tackle. There are more than 4,000 plants species found in Florida, of those 1300 or more are non-native or invasive. Many invasive species are taking over Florida’s waterways disrupting their natural ecosystem by outgrowing and replacing Florida’s native plants. Relieving the damage they cause is not easy, but scientists and members of the communities being affected are finding that it is achievable, as long as everyone works as a team to address the issue.

By the summer of 1940, the British army had suffered in the Battle of France, retreating back to Britain to defend the mainland from German troops. The Germans pressed forward as Hitler desired any piece of British soil to use as propaganda to show the might of the German forces. The Germans invaded the demilitarized Channel Islands on June 28, 1940 leading to a new reality of life for the islanders. Multiple perspectives exist on the British neglect of the Channel Islands. Channel Islands Invaded by Simon Hamon shows how German brutality encompassed the lives of the islanders after the British failed to defend them.

Another invasive species are the Nutria. The Nutria comes from South America. It is not exactly clear

Invasive species, unlike Mauna Loa, only affect Hawaii negatively. A quote from Hawaii Invasive Species Council states that “If brown tree snakes were introduced to Hawaii, they could potentially cause the extinction of our native bird species, and could cost an estimated $2.14 billion a year in damages to electrical infrastructure and medical costs associated with snake bites” (Hawaii Invasive Species Council). This results in not only the people having been bit affected, but the people in that area are being affected, too. Not to mention that an invasive species, called the Little Fire Ant,”infests beach parks, homes, and habitats of native species, resulting in in painful stings, lost crops, and injured pets” (Hawaii Invasive Species Council).

With the increasing amount of disturbed habitats, invasive species could soon become the leading cause of ecological degradation (Soulé & Orians, 2001).  Invasive species can alter habitats in a number of ways.  Changes in the physical structure of the land are the most visually obvious.  Examples include narrowing stream channels, reducing sand supply to dunes, and stabilizing surfaces such as mudflats, and each invasive species goes about these changes in their own way.  For instance, the burrowing activities of Australian isopods cause the banks of tidal channels to collapse, leading to the widening of channels and the loss of vegetated salt marsh (Cox, 1999).  On the other hand, Japanese mussels that have invaded the San Diego area are stabilizing mudflats.  Although reaching Southern California in the 1960s,

The impacts on biotic factors are obvious. One-third of the island’s 1,600 unique species of plants

What makes something invasive? Is it when the object takes over? When it reproduces to a great extent? When it takes over all of your space? These are all aspects of an "invasive" thing. Invaders cause other tiny problems along the path of their destruction that can be difficult to control. In Mark Sanchez's, "The Invaders," and Aaron Hartman's, "Kudzu: From Pretty Vine to Invasive Pest", two plants, the milfoil and kudzu, are taking over. These invasive weeds have more than just being invasive in common with each other, they also share a hand full of dissimilarities. These plants have gobs of similarities and differences between each other.

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.
