Many species can qualify as invasive. They can be plants, bugs, mammals, fish etc. They can be an aggressive native species, or a non-native species with no local predators. Whatever form they come in, they can be devastating to an ecosystem. Without any real competition for resources, these plants and animals can quickly use up food, nutrients, water and space. Most of the time they are transported as a result of human activity, which puts the responsibility for managing them on us. National Geographic has covered all of the basics in their Invasive Species 101 video.After watching it you should have a to solid foundation of knowledge about these species and the impact they have on the ecosystem. | |
