Terrestrial invasive species are land-living organisms that negatively impact our communities, fields and forests. They can decrease our enjoyment of nature, increase the cost of living, and even put our health at risk.
Methods of Introduction
An unfortunate byproduct of world travel and trade is the introduction of unwanted invasive species. Shipping pallets and crates, luggage, the ballast water of boats, and even people can unintentionally transport invasive plants, insects, and diseases to new areas. Without knowing that they would become problematic, some species have been introduced intentionally for use in landscaping, agriculture, and other purposes.
Impacts of Terrestrial Invasive Species
Invasive species impact all aspects of life, from recreation to livelihood. Spotted knapweed is an invasive plant that can take over crop fields, limiting crop production and feed for livestock. Hemlock woolly adelgid is an invasive insect that defoliates and kills hemlock trees; a key species in maintaining important habitat along waterways. Whether damaging the economy or the environment, invasive species can destroy the places we love and require costly solutions.
