Cogongrass (Imperata cylindrica) is one of the world’s ten worst weeds and has already invaded 153 billion acres worldwide. In Florida alone, it has infested one million acres, where it has displaced many native species of plants. It has also been found in South Carolina.  It can quickly displace other vegetation in forests and fields, including native plants that birds and small animals need for shelter and forage.
