Japanese Knotweed Essay

It is known as “the vine that ate the South”—Kudzu. Native to Japan and southeastern China, this invasive species spreads like wildfire in its new home in the southeastern United States.

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.

With government approval, certain beetles have been used to help reduce the number of Purple Loosestrife. Hylobius Transrersovitiatus and Nanophyes Marmoratus are a weevil that lays larvae and adults feed on the Purple Loosestrife roots, along with the Galerucella Pusilla and Galerucella Calmariensis, which are types of beetles that feed on its foliage and flowers. These beetles and weevils have reduced the Purple Loosestrife by at least ninety percent, but for large areas infested by the Purple Loosestrife, herbicidal is required for removal. The only problem with the chemicals used is that it can cause nearby plants to dye. Over a period of several years, the chemicals can reduce to only small areas being infested by the Purple Loosestrife, which promotes other plants to reappear. The Triclopyr and Imazapyr is a chemical used and is

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.

Habitat: Commonly found in terrestrial. Forest light gaps, slips, margins, disturbed sites, open habitats, riverbeds, cliffs, inshore and offshore islands, fernland, herbfield,

A large number of Japanese initially migrated to Hawaii in the late 18th and early 19th century as a result of enormous boom in Hawaiian sugar industry. They also entered

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.

There were four main invasive plants Himalayan Blackberry, Morning Glory, Reed Canary grass, and English Ivy. Carolyn then started to tell us the difference in the shapes

“Hemlock wooly adelgid was first discovered in the eastern United States in Richmond, Virginia in the 1950’s, likely originating from a population in southern Japan”, according to the text “Eastern Hemlock Conservation Plan.” The insect is also invasive because it damages the ecosystem. Hemlocks are a major part of some forest ecosystems and provide some unique benefits, but the Hemlock Wooly Adelgid is killing Hemlocks throughout

This invasive species was discovered in Vaughan and Toronto in 2003. Meanwhile, the beetle came to North America in the 1990’s. The beetle’s came in goods being shipped from China. They came in solid wood packaging of pallets and crates. Today, crates and pallets are being checked more cautiously so no more beetles come infect our trees. The arrival of the asian longhorned beetle has impacted us in many ways.

Invasive species have a variety of impacts, many of which are unpredictable. The Africanized honey bee (also known as the “killer bee” in the media community or apis mellifera scutellata among scientists) provides an excellent case study of how even an intentionally introduced invasive species can become uncontrollable and problematic.

There is a long history of failed attempts of biological controls in Hawaii. The one ingrained in everyone’s mind is the day hunting mongoose released to control nocturnal rats in the 1800’s. However, a stricter quarantine process was set up by the State since and there have been numerous effective bio-controls. Within the last four years the Erythrina Gall Wasp has rapidly become a highly invasive pest in Hawaii. Facing no long-term control other than bio-control the Erythrina Gall Wasp’s cousin has been released throughout the islands to save Erythrina plants.

Cheatgrass is the common name for the species Bromus tectorum L. and belongs to the grass family Poaceae (USDA 2015). This invasive plant was originally reported in eastern North America but now it is dominant in the Intermountain West (Huttanus 2009). The genetics of 192 North American populations of Bromus tectorum is studied so far (Huttanus 2009). Cheatgrass grows mostly in coarse texted soils whereas it cannot develop in saline or compacted soil (USDA 2014). In addition, it can invade rapidly in troubled areas such as burned areas, overgrazed rangelands, and cultivated fields. The spreading of the plant to shorter distance occurred as a result of transportation of hairy seeds by wind, birds, water, and to greater distance by vehicles carrying seeds in its undercarriage (USDA 2014).

Gentianas grow around short grasses on stoney hill sides and mountains. They like a lot of sunlight and most of the time they live in crop fields.

New Zealand is one of many countries around the world that imports plants and plant products, which has also created a pathway for movement of plant pests including, invertebrates, weeds and microorganisms. Other researchers have identified that cross border movements is a risk to the biosecurity of the importing country and the literature also often outlines mechanisms to manage the risk. Such as Whattam, Clover, Firko & Kalaris (2014) who outline specifically why border control operations are necessary and what the ultimate objective of a phytosanitary regulatory system is:
