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.

In studying the problem of hydrilla Florida waterways, it was apparent that management of this invasive species must take an interdisciplinary approach. The economic indicators with the possibility of lost revenue, water usage, and habitat biodiversity drive the need for control. According to Corn, at the federal level there is a need for comprehensive legislature to address invasive species. The current process in reporting an invasive species problem can run into time constraints working through the many agencies to achieve funding. A rapid response is desired to quickly remove the plant before it spreads beyond the ability to control. It is believed that hydrilla is so wide spread today that control can only be achieved through managing feasible levels of it within the limits of funding. Two new integrating approaches are proposed to aid in the goal of reaching sustainable

In a land far far away called Skittonia. Skittonia was known to have to best skittles in the world, mostly every kid went there for the summer just to come home with bags of skittles. A boy named Jimmy really loved skittles and hoped for one day to go to Skittonia, but Jimmy lived in a poor country. It was hard for him because it was his dream to go there but there was no money to get there, until Jimmy found out that Skittonia was having a little contest. The contest was that whoever found a ticket inside the bag of skittles was able to go to Skittonia.

One environmental issue that the great lakes watershed has been exposed to is invasive species. An invasive species is any organism that is foreign to an ecosystem and causes harm (United States Environmental Protection Agency, 2016). In ordered to be classified as foreign they do not have to be from a different country but they just must be a non-native to an established ecosystem. Some of the species travel at their own will but they primarily spread through human activities unintentionally. As we import and export goods, or travel, some uninvited species may ride along and travel to new places. Organisms can be stowed away in ships or products like wood. Some ornamental plants may

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.

Significance: The question of whether or not invasive species impact the environment is an important one. The answer affects everyone. In today’s world, we take the outdoors for granted. People don’t realize how much it does for us. It provides economical resources, areas to relax, and oxygen for us to breathe. Without these simple things our lives would change drastically. Life as we

According to Silent Spring, the United States Office of Plant Introduction has introduced about 200,000 species of plants from around the world, and almost half of the 180 major insect enemies of plants are accidental imports. According to Campbell’s Biology Textbook, these imported animals are known as invasive species, organisms that become established outside their native range. Carson states that often when a species is brought to an area they are not native to, the lack of natural enemies causes the species to become dominant and extremely abundant. These invasions are likely to be permanent, however as a way to “buy time” humans have turned to quarantine and massive chemical campaigns, instead of trying to prevent new invasions. As Carson continuously stresses chemical use can have unwanted consequences and she urges people to use the basic knowledge of animal populations and their relations to their surroundings and other species to prevent them from becoming overly dominate. For example, according to Campbell’s textbook, higher diversity communities are more often resistant to invasive species because the species is less likely to dominate over the native species. This was proven by scientists working in Long Island Sounds off the Coast of Connecticut created communities of different diversity consisting of sessile marine invertebrates, and examined how vulnerable the experimental communities were to an invasive species: the exontic tunicate. They found the tunicate was four times more likely to survive in lower diversity communities than higher diversity communities. It was concluded the diverse communities captured more of the resources available, leaving fewer resources for the invader. It is firmly believed by Carson that people should do much more simple research before transferring a foreign species to a new habitat to not only prevent a

The St.Lawrence river is a large tourist attraction for northern New York. With invasive species being introduced to the river and the land surrounding they have affected the way the river looks and the species that are in it. Any plant or animal found outside of its normal range is considered to be invasive to the area it is now located. There has been an estimated 163 invasive species that have been discovered in the Great Lakes and the St.Lawrence since the late 1800’s. Of the 163 species that have been unintentionally introduced to the area, 85 of them reside in the St.Lawrence river. The variety of non-native plants and animals in the St.Lawrence river and surrounding land have had a continuing negative effect on the native ecosystem.

There is one more aquatic invasive species. Have you ever seen the aquatic invasive species on the lake? This is Eurasian Watermilfoil, which are also found at Fort Snelling State Park. It was suddenly introduced to North America from Europe. The main reason why Eurasian can rapidly reproduce is that a single segment of stem and leaves can take root and form a new colony through stem fragmentation and runners. / Reproducing from lake to lake creates numerous amounts of new stem fragments while they cling to boats and trailers. / There are biological control and Invasive species program, which is to curb the spread the growth of Eurasian Watermilfoil. Using minimum of herbicides and imposing mechanical removal are to reduce them, but there is

The environment is full of invasive species, some more invasive than others, but this is about zebra mussels and garlic mustard. Zebra mussels are small clams that attach to solid surfaces in water. They have D-shaped shells, yellow and brownish colored stripes. They are native to Eastern Europe and Western Russia and were brought over to the Great Lakes from ships in 1988. Garlic Mustard begins as a kidney-shaped garlic-smelling leaves in the first year. The second-year plants grow a stem up to 4 feet tall with triangular barbed leaves and small white four-petaled flowers in clusters at the top of the stem. It is invading our lawns, woodlands and other areas and poses a severe threat to native plants.The first recorded observation of garlic mustard in the United States was on Long Island, New York in 1868. Since 1868 garlic mustard has spread to thirty U.S. states and three Canadian provinces. Zebra mussels are worse compared to garlic mustard.

My aquatic invasive species is the water chestnut. Though it is not too common in Indiana waters, it is on the invasive species list, due to the prediction that it will quickly become a threat. It is an aquatic plant native to Eurasia. Currently, it is naturalized in North America and Australia. The states that it is most common in Connecticut, Delaware, Maine, and others on the eastern coast.

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,

Humulus japonicus, also known as Japanese hop, is a dioecious plant native to temperate and tropical Asia (National Park Service). Japanese hop was originally introduced in the United states in the late 1800s as an ornamental vine (National Park Service). Japanese hop was later introduced to Wisconsin in the late 1990s; it is believed that Japanese hop was introduced via construction along Blockhouse Creek in southwestern Wisconsin. Since then, Japanese hop has become an invasive plant common to riverine wetlands (Ju et al., 2006). In recent years, Japanese hop has spread to a majority (about 30 states) of the United States as well as parts of Canada (USDA). The spread of Japanese hop is primarily accomplished via hydrochory, dispersal by water (National Park Service). Although Japanese hop does also spread via zoochory, dispersal via animals, hydrochory seems to be the main method of dispersal for Japanese hop. Japanese hop is known to grow and spread rapidly annually; rapid growth of Japanese hop poses a problem to native plant species and around these plants, because the plant grows over an obstacle to the surrounding native plants by potentially strangling the plant or eliminating availability to light for the native plant. (Ju et al., 2006).

The Camphor Laurel spread by birds, animals, water and garden waste or suckers, Cabomba in contrast is encouraged by water movement that breaks the plant into segments, allowing them to travels through the water flow to new areas of the waterway. The Cabomba thrives on light, nutrition, muddy water and doesn’t die in salt water. Cabomba multiplies rapidly through vector of human activity, as a segment of the plant can survive out of water for large periods of times, allowing it to be transported to new areas not connected to the water system which was initially effected.

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.
