Invasive Species
An invasive species is one that is not native to a particular ecosystem and that does or is likely to cause harm to the environment and/or the economy (Exotic Species in Illinois). For example, a Multiflora Rose (Rosa multiflora). This rose, also known as the baby rose, it is native to eastern Asia, and was introduced to the U.S. in the late 1700’s. The baby rose impacts an environment, by forming dense thickets that invade pastures, and crowd native species (Plants).
Invasive species can cause harm in so many ways that it isn't practical to cover them all here. Below is just a sample to give you an idea of how widespread this problem is. Many of these changes are things you can see happening around you.
When a non-native species is introduced into a new habitat, it is freed from the natural animals,prey, and predators, our competitors from its native habitat. This gives an advantage to non-native species competing with the native species that evolved in the community. These advantages allow the non-native species to outcompete native species for the available food, water, light, and space. Wherever a harmful plant is growing is where a native plant should be.
Invasive species also have the possible ability to disrupt very important community functions, such as water flow, nutrient cycling, fire systems, or soil. An example of this is the Tamarix species. It not only uses large amounts of water, it changes the soil chemistry, making it more salt water. This can …show more content…
