The wetland plant purple loosestrife was imported to North America from Europe. Since its introduction, the loosestrife has spread, which has resulted in a dramatic decline in the biological diversity of native wetland plants. A likely reason for the spread of the purple loosestrife is that it can:

Serve as an excellent food source for native herbivores.
Successfully compete with native plants for space.
Prevent the migration of native plants.
