  1. Not native to and tending to spread widely in a habitat or environment. Invasive species often have few natural predators or other biological controls in their new environment. Although not always considered harmful to an environment, invasive species can become agricultural or ecological pests and can displace native species from their habitats. Invasive species are often introduced to an environment unintentionally, as the zebra mussel was to the Great Lakes, but are sometimes introduced for a purpose, as kudzu was to the southern US, where it was originally planted to control erosion.
