The Weed Science Society of America is championing a National Invasive Species Awareness week this week in effort to improve understanding of invasive species prevention and management strategies.
The designated week wraps up Friday.
Invasive species – non-native plants, animals and pathogens – can harm humans and the environment and impact our nation's economy, WSSA says. The damage done by invasive plants alone costs the U.S. an estimated $34.7 billion a year.
Invasive weeds can produce skin irritation, trigger allergies and poison pets and livestock. They can clog waterways, kill native trees, and shade out crops, ornamentals and prized native flora.
They are also found in every imaginable habitat, including oceans, lakes, streams, wetlands, croplands, rangelands, natural areas, parks, forests, urban environments, yards and gardens.
"Though the impact of invasive species is profound, there are important steps we can take to manage infestations and prevent their spread," says Lee Van Wychen, Ph.D., director of science policy for the WSSA. "It all begins with awareness."
Ways you can help
WSSA says there are 8 ways to help curb the spread of invasive species:
• Learn about invasive species, especially those found in your region. Your county extension office and the National Invasive Species Information Center are both trusted resources.
• Clean hiking boots, waders, boats and trailers, off-road vehicles and other gear to stop invasive species from hitching a ride to a new location.
• Avoid dumping aquariums or live bait into waterways.
• Use forage, hay, mulch and soil that are certified as "weed free."
• Plant only non-invasive plants in your garden, and remove any known invaders.
• Report new or expanded invasive species outbreaks to authorities using the WSSA list of contacts.
• Volunteer to help remove invasive species from public lands and natural areas.
• Ask your political representatives at the state, local and national level to support invasive species control efforts.
