A new law aims to significantly strengthen the fight against invasive weeds in the United States, helping restore native plants and ecosystems nationwide.

The Noxious Weed Control Act enables the Secretary of Agriculture's office to assist eligible weed management agencies in responding to noxious weed problems on public and private lands.

“With invasive plant species infesting an estimated 100 million acres across the United States, the Noxious Weed Control Act is a strong step in the right direction,” said Rob Hedberg, director of science policy with the Weed Science Society of America.

In the United States, invasive plants displace native species by a rate of 8% to 20% annually. For example, thirsty invasive brush such as saltcedar can threaten vital water supplies. A single plant is capable of consuming as much as 300 gallons of water a day—or about 6000 gallons per month. In comparison, the average American household uses about 8000 gallons of water per month.
