Overview

Invasive species are harmful, non-native plants, animals, and pathogens that damage our economy and environments. Invasives can move into and dominate both natural and managed systems by disrupting the ability of those systems to function sustainably. They are highly competitive, persistent, and can create monocultures that will eliminate Idaho’s diverse biological landscape—a landscape that nurtures Idahoan interests from our recreational pursuits to our ability to help feed the nation.

These threats include:

  • Pests that threaten agricultural commodities.
  • Forest pests, including those that may attack commercially valuable timber species and those that threaten shade trees found mostly in urban settings.
  • Diseases that threaten the health of humans or domestic animals and wildlife.
  • Nuisance exotic animal species that can displace or compete with native species.
  • Noxious weeds that displace ecologically or economically valuable native rangeland species or agricultural crops or threaten the integrity of streams and lakes.
