North America Invasive Species Management Association.
The North American Invasive Species Management Association (NAISMA) announces a new addition to its Certified Weed Free Products Program: weed free mulch. Many federal, state, and local lands require the use of certified weed free forage, gravel, or mulch on their properties because invasive plants or noxious weeds cause serious harm to the environment, agriculture, and the economy. Once introduced, weeds can be difficult to control and expensive to manage.
