The Iowa State University Extension display at the Iowa State Fair Aug. 11–21 will identify invasive species that are threatening the state. Look for the display in the exhibit hall under the east end of the grandstand. The display hours are 9 a.m. to 9 p.m. each day of the fair.

Invasive species have been accidentally or intentionally introduced into an environment from which they did not evolve. Because they have no natural enemies to limit their reproduction, they usually spread rampantly. Invasive alien species threaten the state’s biodiversity and cost agriculture, forestry, fisheries and other human enterprises an estimated $137 billion annually.

The ISU Extension display will highlight those plants, animals, diseases and insects threatening to overtake Iowa’s landscape. Vivid photos or examples of several species will be on display. Visitors will learn how these species are harming Iowa’s environment and what Iowans can do to stop, and even reverse, their spread.
