Introduced species have had a drastic effect on Australian agriculture’s production and economy, and continue to pose an ever-growing threat. Invasive plant species are highly adaptable, resistant to control and spread aggressively. Methods of controlling these invasive species can often be expensive, time-consuming and controversial. Introduced plants can have drastic effects on natural ecosystems by smothering native vegetation, degrading creeks and rivers, and spreading diseases. Sometimes introduced vegetation species provide shelter for native animals. Animal agriculture is greatly affected by introduced species through deterioration of fence lines, poisoning livestock and creating impenetrable fortresses of plant matter, often hindering mustering practices. Lantana camara is destructive, toxic and detrimental to the economy of the agricultural industry. Efforts to control this plant have not been successful.…

The watershed my partner and I chose to implement techniques to eliminate invasive plant species is the American River watershed. The American River drainage covers 1900 square miles of the Tahoe and El Dorado National Forests, including the Granite Chief Wilderness and Desolation Wilderness. Flowing west from the peaks of the northern Sierra Nevada west of Lake Tahoe, its streams gradually converge into the South, Middle and North Forks of the American River. It is a classic multi-use watershed, supporting mining, hydroelectric generation, timber cultivation, and many forms of recreation.…

Invasive species are organisms that infiltrate ecosystems that are unable to support their alien lifestyle and diet. Their initial invasion may seem inconsequential and, frankly, insignificant at first, but their numbers will quickly grow and multiply, so much that the future outcome takes a drastic turn for the worst. Florida, in particular, has been attacked by numerous invasive species because of its accessibility to foreign cargo and material. The Burmese python, Cuban treefrog, and lionfish are just a few of the infamous invasive species growing in prominence throughout Florida. Even though these species seem incredibly different, they have one thing in common - an ability to tear down entire ecosystems by just being alive! It is important…
A biome is a large, distinctive, complex community of plants and animals in a region maintained by climate. There are different types of biomes including tundra, taiga, deciduous forest, scrub forest, grasslands, desert and rain forest. Scientists disagree on the exact number of biomes in the world.…
Conservation and preservation activities are currently part of all national forest management programs. The “Bridger Teton Environmental Science” video discusses the controversy between those who want to harvest the resources of one section of the forest in an environmentally friendly way and others who believe it should be left in its original state.…
The kudzu problem, also known as the invasive species Pueraria montana var. lobata, currently rages across the Southern US, drowning out the native vegetation and covering anything in its way, including human architecture. However, the kudzu faces the same upcoming trials as we do—climate change. Will the kudzu, having already stood the test of migration, handle the coming climate shift just as well? To answer this question, we examine the three characteristics of kudzu that allow it to succeed as an invasive species, outcompeting both native species and human landowners, and how these same characteristics…
A non-native, invasive species of plant in Nebraska is the Canada thistle. A non-native, invasive species of mammal in Nebraska is the Norway Rat, more commonly known as the brown rat. A non-native, invasive species of fish in Nebraska is the common carp. A non-native, invasive species of bird in Nebraska is European Starling. A non-native, invasive species of reptile is the Cumberland Slider. Obviously, all of the species are not native to Nebraska. Both the Canada thistle and the Norway Rat can harm the environment in which it lives. The common carp and the European Starling are both dominating the environment in which they live in.…
Johnny had lost no time in getting to work. From soil as soft as loose as an ash-heap he pulled forest seedlings and weed-stalks by hand. Tough bushed, briars, and saplings he cut down with his hatchet, grubbed out the roots; and with his hoe he destroyed the inumberable cones of annuals that, pushing through the blanket of drifted leaves, ran up every rise in flickers of pale-green fire. The ground cleared over a fraction of an acre on the well-drained slope that faced westward toward the river, he raked it free of clods, opened orderly rows of trenches, and put in and covered up his seeds.…
The abundance of native tallgrass prairies have been declining for the past century, and are being replaced by urbanized landscaping. As it has been studied, the area of tallgrass prairies have declined over 82% since the 1800s (Larsen et al. 2003).Tallgrass prairies harbor more plant and animal biodiversity, compared to urban landscaping. Thus, the conservation and preservation effort for prairies should increase, in order to maintain this biodiversity. Tallgrass prairies can be protected by either grazing or fire (Larsen et al. 2003). In addition to grazing, or fire, protecting prairies can also be done by conserving the landscape area and elimination any human land use and disturbances to be done on those prairies. If there is not much effort put into maintaining these environments, the prairies will decline more and more as time goes by, which can eventually disturb the populations of some native species. The declining of tallgrass prairies is also disturbing the population of some native species. Introduced species might not be affected by the habitat changes, in which those changes might be into their advantage, and they are able to adapt to their new habitat. This can result in allowing the introduced species to overcome the population of native species, eventually causing a major diversity changes.…
Invasive species are a major threat to the United States; mostly Florida. These species are the worst ones we have in Florida.“We are ground zero for the impacts of invasive species,” says Doria Gordon, the director of conservation science for the Florida chapter of the Nature Conservancy (TNC) . “And our invaders are very good at finding new habitats.” Usually those habitats are around South Florida in the everglades. The mix of suburbs and wilderness around the area of the everglades, makes the Everglades a place where all species can live.…
Invasive species are annihilating the population of majestic creatures. One example of an invasive species is the Pythons, these creatures are invading Florida and will reach New York in 2020. Pythons are extremely elusive, so it’s hard to catch them. Another example of an invasive species are the starling birds, these birds can roost in hordes up to 1 million. Starling birds are lethal because of their droppings which can cause diseases. Additionally, medflies are terrorizing farm fields because of their broad range of appetites for fruit.In addition, about 2.3 million wild pigs are in Texas, and they have a large appetite for deer, quail, lamb, and calves. They also destroy land and cause approximately $400 million dollars of repair a year.…
In many opinions, invasive species becoming introduced to a different environment is not deemed acceptable. With many situations incorporating these species, they are sought to be pests, only trying to make lives difficult for others. Many also have come to believe, from experience, that these insidious species cause harm to the environment of which they are newly exposed to. The businesses and/or government agencies that bring invasive species to a new environment must consider many measures before transferring and following through with brings the species forth to a new location. With careful considerations of transportation, other natural predators, the actual environment and the sole purpose, the business and/or government agency must vigilantly take into consideration the actions it is about to partake in.…
An invasive species such as the zebra mussel, invaded the Great Lakes of America in 1988. They were brought in by seagoing vessels that emptied their ballast water as they got in the port, the zebra mussels had hitched a ride in the water taken in in the ballast before the ship left port in the Caspian and Black seas. By 2010 these muscles and colonized the waters in over 30 US states spreading like wildfire. Invasive species have a huge impact on their nonnative environment, the zebra mussel clogs and take pipes at factories in water treatment facilities that can degrade docs and ruin fishing gear. But it’s not the only invasive species after reading this chapter I decided to look up a little more online about invasive species, it seems that…
