1. Introduced Species

1.1. Introduced species, also called alien species, are those that have been moved by humans to an environment where they didn't occur naturally. The term can refer to animals, plants, fungi, or microorganisms that are non-native to an area. Species introduction can be accidental or intentional.

1.1.1. 1. Eastern Gray squirre, Sciurus carolinensis

1.1.2. 2. Brown tree snake, Boiga irregularis

1.1.3. 3. purple loosestrif, Lythrum salicaria

1.1.4. 4. Caulerpa taxifolia, seaweed

1.2. An introduced species (also known as an exotic species) is an organism that is not native to the place or area where it is considered introduced and instead has been accidentally or deliberately transported to the new location by human activity.

2. non-native species

2.1. Non-native species are also know as introduced species and some can be considered ‘invasive’.

2.1.1. 1. Arum Lilly, Zantedeschia aethiopica

2.1.2. 2. Red-eyed wattle, Acacia cyclops

2.2. Non-native species are simply ‘not from here’, invasive species are unstable and unpredictable.

2.3. Newly introduced species can cause problems for humans whether they are native or non-native.

2.4. Non-native species can become such a common part of an environment, culture, and even diet that little thought is given to their geographic origin.

3. Invasive species

3.1. An invasive species is an organism that causes ecological or economic harm in a new environment where it is not native. ... Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats .

3.1.1. 1. Zebra Mussel, Dreissene polymorpha

3.1.2. 2. Kudzu, Pueraria montana var. lobata

3.1.3. 3.Asian long-horned beetle, Anoplophora glabripennis

3.1.4. 4. Northern Pacific seastar, Asterias amurensis

4. Exotic Species

4.1. Exotic species, which are also known as alien species, invasive species, non-indigenous species, and bioinvaders, are species of plants or animals that are growing in a nonnative environment. Alien species have been moved by humans to areas outside of their native ranges

4.1.1. 1. European Starling, Sturnus vulgaris

4.1.2. 2. Brown Anole, Anolis sagrei

4.1.3. 3. Brazilian Pepper, Schinus terebinthifolius

4.1.4. 4. Nine-Banded Armadillo, Dasypus novemcinctus

5. Differences

5.1. A large percentage of the food we produce in this country comes from non-native species. The majority of non-native species never causes a problem. Unfortunately, the few that do cause problems more than make up for the rest of them. This small percentage of non-native species causes a tremendous amount of harm to our native habitats and the plants and animals that inhabit them; to natural areas such as forests, lakes, and rivers that we use for recreation; to agriculture; to our economy; and directly to humans. These harmful exotic or non-native species are called invasive.

5.2. When a non-native species is introduced into a new environment it is freed from the natural predators, parasites, or competitors from its native habitat. This gives an advantage to non-native species competing with the native species that evolved in the ecosystem. These advantages allow the non-native species to outcompete native species for the available food, water, light, and space. Wherever an invasive plant is growing is where a native plant should be.

6. Similarities

6.1. They all have in common, that their species is in a given location, where they do not originally belong. Those species are placed there by Human activity. This can be accidental or deliberate.

6.2. Exotic and non-native basically mean the same thing. An organism is considered non-native or exotic if it is found in an ecosystem where it did not evolve.
