On 21 June 2007, the Weed Science Society of America issued a statement reminding Americans of the importance of combating invasive species.

The WSSA statement reads in part:

“Invasive weeds are detrimental to our nation’s agriculture, water quality, wildlife and recreation,” says Jill Schroeder, Ph.D., Professor of Weed Science at New Mexico State University and President of the Weed Science Society of America. “Many people may not realize that weeds interfere with the production of our food, cultivation of feed for livestock and crops grown for textile production. Invasive weeds are considered biological pollution and it’s a real problem. In fact, the economic impact of weeds in the U.S. has been estimated at a staggering $34.7 billion annually, according to a Cornell University report.”

Each year, invasive plants claim another three million acres in the U.S. That’s an area about twice the size of Delaware. When they proliferate, they can choke out native plants, forever altering entire habitats as animals lose food, shelter and water to these persistent intruders. Currently, numbers of invasive plants are on the rise as increased land development disturbs previously untouched areas and global trade breaks natural barriers.
