Invasive plants are non-native species that spread rapidly in new environments, often outcompeting local flora. They can disrupt ecosystems by altering habitats, reducing biodiversity, and affecting the food chain. These plants thrive in various conditions, making them difficult to control. Common examples of invasive plants include kudzu, Japanese knotweed, and purple loosestrife. They can be introduced accidentally or intentionally, often through gardening or agriculture. Managing invasive plants is crucial for protecting native species and maintaining healthy ecosystems.
