Certain plants in your yard might be causing natural areas to suffer. Some aggressive plants that have been commonly used in landscape beds can be migrated to natural areas when their seeds are spread by wildlife or wind.

Biologists are studying the mechanisms underlying a taxon’s ability to become invasive, but it can be difficult to predict whether or not a species will become invasive in a new habitat.
