How does an invasive species affect the ecosystem?
Some invasives spread so rapidly that they stifle other species. An invasive plant, for example, could change a forest, meadow or wetland into a landscape dominated by one species. Such monocultures (stands of a single plant species) have little ecological value and greatly reduce the biodiversity of an area.
