Invasive Species Alien Invasive Species
Introduction and Justification:
Introduction:
Verbena bonariensis is a fast growing NEMBA category 1b alien invasive species known for growing in grasslands, moist areas and along pavements and roadsides (Invasive Species South Africa, 2018) The plant possess threat to local plant life as it takes up growing space and uses up resources such as water.
Justification:
I live one street away from Delta Park and have noticed the clean-up operations that are ongoing in the Florence Bloom Bird Sanctuary. I would like to further my understanding on alien invasive species Verbena bonariensis, which is the main targeted alien invasive in the sanctuary and the reason as to why the plant pose a threat to the local plant life of the sanctuary.
Hypothesis:
The average amount of Verbena bonariensis will be higher than the average amount of other natural occurring plants growing in the Florence Bloom Bird Sanctuary.
Aim:
To determine the average amount of Verbena bonariensis versus the average amount of other natural occurring plants growing in the Florence Bloom Bird Sanctuary.
Literature Review:
Aliens and vagrants threaten Delta Park (22 October 2014)
Alien invasive species and vagrants pose threat to the natural biodiversity of Delta Park. The vagrants pollute the park and there has been evidence of the vagrants trapping birds from the Florence Bloom Bird Sanctuary.

Conrad's Beach Ecological Succession Report
1014 Words | 5 PagesWhen reviewing figure 3 it has been noted that most of the species are more abundant further in the woods and the most significant change is in the moss and the amount of coverage which was substantially different depending upon the distance from the dune to the woods. The numbers fluctuated - dropping slightly at 60 m and rising to its highest point at 75 meters. Trees also had a very noticeable change in their percent coverage starting below 10% and rising close to 5 percent every 15 meters. The other plants did not show any specific trend of growing more the further way from the dune but this could be due to where the quadrants were placed as each team placed their quadrat down every 15 meters which resulted in a lot of ground left uncalculated. This could be the reason for lack of trends with other plants.
Essay On Clapper Rail
514 Words | 3 PagesThis article included many information such as,“Clapper rail survival patterns were consistent with hybrid Spartina providing increased refuge cover from predators during tidal extremes which flood native vegetation, particularly during the winter when the vegetation senescence” (Invasive Species…). We know that the most important factor that affects the clapper rail’s population is their surrounding, in order to help them we must start by removing invasive plants and replace it with plants that is helpful. The increase in invasive plants decrease the amount of spaces in which the clapper rail can build their nest, it causes many birds to die because of the lack of habitats. The invasive plants can also kill the harmless plants by taking away their nutrient, and it might take away all the possible space for nests. We can change this by replacing the invasive plants with harmless plants and even build nests for clapper

Ungullate Case Study
201 Words | 1 PagesGroup 1: How might the ungulates introduced to Hawaii affect the habitats of native birds? Ungulates, which included cattle, goats, pigs, sheep and horses, are seen to cause devastation of native plants and forests that are the native birds’ habitats. Also, majority of the bird species living in the main island are being restricted to live only on 2 forests because of the decrease in forests; however, due to the feral cattle that eat through native forests, they are threatening the native forest birds and their habitats. Pigs and goats are also seen to cause a serious damage by feeding on native tree ferns and young trees, destroying the woods in which the birds nest.

Easter Island Case Study
510 Words | 3 PagesCurrent levels of plant and biodiversity on Easter Island in comparison with the past biodiversity levels, have significantly lowered. Today, Easter Island has a neutral climate, fertile soil, withered lands, and only forty-seven identified species. In contrast, historical Easter Island consisted of tropical forests with different species of trees and different species of animals. 5. Today’s levels of biodiversity on Easter Island can be explained in terms of complexity and disturbance because the Easter Island population unknowingly overexploited their island’s natural resources because they were isolated from other islands.
Unauthorized Immigrants
104 Words | 1 PagesIllegal immigrants are a major part of the US labor force and have been an important source of low-skilled labor supply to the US economy for many decades.

Hawaii Invasive Species Essay
3398 Words | 14 PagesInvasive species have been a massive problem in Hawaii since the 17s and 18 hundreds. At first, it wasn’t that big of a deal, but the influx of invasive species grew over time, and it became a dangerous slippery slope. Species that were once alienated poured into Hawaii and destroyed indigenous species that had been native to Hawaii for a very long time. Since then, the Hawaiian people and advocates of removing invasive plants and animals have banded together to help remove these species. There has been a great global effort to remove invasive species in all places, but the hasty spread of them has made it almost impossible to eradicate a lot of them. I think my group can majorly help with this by educating you all about the seriousness of invasive species.
Descriptive Essay: Description Of The Lake

The only occupants were rodents and spiders who had set their home in the dank, forgotten shack. From its base, dead, brown grass reached out, all the way to the edge of the tree-line, unable to survive in the perished, infertile soil that made up the foundations of the house. Bird houses and feeders swung still from the once growing apple trees, in the back garden, consigned to a life of
