Introduced species are affecting plant and animal communities all around us.  An introduced pest in Idaho is designated as an "Invasive Species" when it is considered to be capable of causing economic or environmental harm and has the ability to spread throughout the state.  Invasive species are highly competitive, persistent, and can create monoculture that eliminate the diverse biological communities Idaho ecosystems require for sustainable function.

Invasive pests are primarily spread through human activities and have been done so intentionally and unintentionally.  Increased trade, travel, and tourism have all contributed to the movement of invasive species across continents and oceans; some species find their way accidentally by hitching a ride in cargo or ballast tanks while others are knowingly brought in through the pet and aquarium trade.
