Japanese Knotweed Research Paper

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.

Invasive species are very common all over the world. Invasive species are an organism that lives in an ecosystem in which they don’t belong. Invasive species are not only dangerous to people, but also the ecosystem and must be removed.

If I had lived during the Holocaust, the hardships would include lack of shelter, starvation, and survival. To start, people struggled to find a safe shelter. The book Milkweed is about a boy who has to change the locations of his shelter to be able to survive. I know that during this time period a lot of people who were jewish were taken to concentration camps were they were forced to work and were treated harshly. Because of this people had to change the location of their shelter to escape getting caught. Additionally, people also had to face the struggles of starvation. Since hitler and his nazis were killing off a lot of people, the people who owned food stores could no longer sell food. This meant that people couldn’t get the same amount

On May 15, 2016 me and around 20 other University of Washington students volunteered to remove invasive plants from Yesler Swamp. We started the day by meeting in front of the Yesler Swamp trial sign. After that, our guides started to introduce themselves there was three of them. Then, started walking on the trail to reach our designated spot that we are going to on. While we were walking Carolyn, one of the guides, started explaining what we are going to do. She started inform us about the different type of plants and which ones we should take out, invasive plants, and which we should leave, native plants.

Georgia has been invaded by numerous species that are known as harmful exotic plants and animals. It is so costly to attempt to control invasive species and the damages they inflict cost the United States annually an estimated $137 billion (Georigia Invasive Species Task Force, 2005). For example, in South Georgia there is an estimate of 7 million acres of Kudzu vine that originated in Japan and China. The damage that arises with the Kudzu vine is that it grows up to one foot per day and overgrows and shades out trees, covers houses, barns and road signs (Georigia Invasive Species Task Force, 2005). In order to make this a top priority some things congress needs to change is the revision of current United States policy on importation of live plants and animals and when considering, reviewing, or approving trade agreements they address specific invasive species. In addition, the implementation of prescribed burnings in areas with invasive species will help eliminate and control the spreading of such invasive species.

Then in the early 1970’s, a large seed reservoir was present and effectively cultivated a crop of spotted knapweed where the soil had once been disturbed (SCWD, n.d.). This infestation had remained unattended to until 1983, when the Stillwater Mining Company began operations. The Stillwater Mining Company began aggressive measures to control the spotted knapweed, but the weed had established itself and began spreading to adjoining private and public properties. Since then, the efforts of the Stillwater Mining Company, local land owners, Untied States Forest Service (USFS), the Stillwater Valley Watershed Council, and Stillwater County have effectively controlled the spotted knapweed in all areas except for along the river corridor (SCWD.

Common species include, Hydrilla, Water Chestnuts, Eurasian Watermilfoil, Asian Clam, Hemlock Wooly Adelgid, Emerald Ash borer and Giant Hogweed. With no natural predators against the species they are able to overpopulate and alter the ecosystem. Doing more damage then just plants getting stuck in your boat propellers but the invasive species can kill of aquatic life.

milkweed within its body and by eating the leaf in a circle it stops the thick liquid inside from coming out and overwhelming it.

An invasive species is a plant, animal, or fungi that is not native to a certain area. These species can cause great damage to an ecosystem, human economy, human health, and other species that are native to the area.

The book entitled, “Ecology of Weeds and Invasive Plants”, opens with a quote from Dr. A. S. Crafts saying, “in the beginning there were no weeds.”. This quote causes one to stop and think about it. What Dr. Crafts meant by this quote was that even though plants have existed for many years, weeds did not exist before humans began to travel about. With all the traveling that humans do the problem of invasive plants has grown tremendously (Radosevich, 1). The impact that invasive species have on the environment is often overlooked or thought of as unimportant. The issue is vast, yet little is done about it. The problem with invasive species is extremely important and will impact the world for generations to come. This paper will explain what invasive species are, show the negative impacts invasive species have on the environment, and what we can do about this issue.

The investigation of this claim was done in the examination of the different types of vegetation with in serpentine soils in California. They studied the climatic correlations and geographical correlations to gain a better understanding of what they were dealing with. The main results included that the diversity of plants widespread to serpentine declined from the north to the south and from the coast inland. Meaning that while there may be many different ranges of this soil that does not mean that the plants living on it are diverse. There was also an association with the amount of rainfall. Most of these overall trends where seen to be true to all the plant groups. Overall they were able to conclude that the “patchiness” in the different habitats do not appear to increase diversity. In the end this journal leads me to the interpretation that while there are many of these environments spread out through California, they are all very similar to each other lacking in overall

Coccinia grandis is a common invasive plant species found on Hawaii (KISC, 2015). This vine-like plant displays broad, flat leaves with star-shaped white flowers, and is characterized by chili-like red fruits (Fox, 2008, p.D8). According to Fox, C. grandis (also referred to as 'Ivy Gourd') is native to parts of Southeast Asia, India, and Africa, and it is likely that this hardy (and hard to eradicate) plant found its way to the Hawaiian islands as a hidden passenger on immigrants from these areas. It is well established that C. grandis is a harmful invasive species posing a threat to native Hawaiian plants and ecosystems in direct and indirect ways. Despite the plant's negative effects on Hawaiian plants, however, research has shown that C.

The control and eradication of invasive species in Washington State is an important part of maintaining the diversity and wellbeing of our ecosystems. One invasive species common to us, Heracleum mantegazzianum, otherwise known as giant hogweed, is a Class A weed and must be eliminated where encountered (Noxious Weed Control Board). H. mantegazzianum is recognizable by its immense height of up to 20 feet, and its thick stalks support umbels of small, clustered white flowers. It can be distinguished from plants of similar appearance by purple blotches located on the stems (Noxious Weed Control Board). They are commonly found near riverbanks and roadsides.

However, we find that Centaurea diffusa, a noxious weed in North America, has much stronger negative effects on grass species from North America than on closely related grass species from communities to which Centaurea is native. Centaurea's advantage against North American species appears to be due to differences in the effects of its root exudates and how these root exudates affect competition for resources. Our results may help to explain why some exotic species so successfully invade natural plant communities. Negative impacts of invasive plants on natives have been well documented, but much less is known about whether invasive plants can cause population level declines. We used demographic models to investigate the effects of two invasive grasses on the demography and population growth of Anemone patens, a long-lived native perennial of North American

This species became invasive because the plant was ok until urban development started and the tree was causing a lot of problems, as well as, hurting other species. The tree also
