While researching a topic, a student has taken the following notes:
  • A nonnative species is considered invasive if it causes environmental or economic harm in an ecosystem.
  • Purple loosestrife is a species of wetland plant native to parts of Eurasia.
  • It can also be found in the northern and western US.
  • There, it crowds out native plants and reduces aquatic nutrients.
  • It is considered an invasive species in the US.
