Invasive Species
/in-VAY-siv SPEE-sheez/🦋 Ecology● Basic
Also known as: exotic invasive, noxious weed
Invasive species are plants, animals, or other organisms introduced to an ecosystem outside their native range that spread rapidly and displace native species. Invasive plants typically lack natural predators and competitors, reproduce prolifically, and outcompete native vegetation. Examples include kudzu, Japanese knotweed, English ivy, and purple loosestrife. Management combines prevention, early detection, and control.
Etymology
From Latin invadere (to enter by force) + Latin species (form)
Example
“Japanese knotweed, one of the most aggressive invasive species, can grow through concrete and reduces property values.”
