Invasive Species (Plants and Animals)

Invasive Species (Plants and Animals)

An "invasive species" is defined as a species that is:

  1. non-native (or alien) to the ecosystem under consideration and
  2. whose introduction causes or is likely to cause economic or environmental harm or harm to human

Invasive species can be plants, animals, and other organisms (e.g., microbes). Human actions are the primary means of invasive species introductions. (Executive Order 13112)

How did invasive species get to Alaska?

Intentional introductions: agricultural crops, landscaping and ornamental plants, released pets, and bait fish.

Unintentional introductions (hitchhikers): freight such as plants, wood, or food that contain invasive species or the seeds, eggs, or spores of invasive species. Boaters moving invasive species that have attached to their equipment or clothing to new bodies of water. Hikers and hunters moving invasive species around through mud on boots and other equipment.
