Invasive Species

What is an Invasive Species?

An invasive species is an alien species whose introduction causes or is likely to cause economic or environmental harm or harm to human health.

Why are invasive species bad?

  • Reduce native diversity by competing for resources, such as space, sunlight, water and minerals.
  • Alter soil conditions by secreting chemicals that inhibit the germination or growth of other species
  • Alter nutrient cycling by changing the amount, composition, or rate of decay of leaf litter.
  • May hybridize with native species.
  • Disrupt natural communities and change habitat structure for other organisms such as birds, mammals, turtles, fish and frogs.
