72 counties have had cogongrass detections since 2007, and to date 34 of the 72 counties have no active cogongrass. Georgia’s proactive treatment program assists landowners across the state, and 85% of all known cogongrass spots in Georgia are considered inactive.

The Georgia Forestry Commission documents all known cogongrass infestations.Invasive Species: Any plant or animal that has been introduced and aggressively competes with and displaces local native communities; normally having no native enemies to limit reproduction and spread.

The Dirty Dozen List of Non-native Invasive Species is ranked by the total acres occupied according to Forest Inventory and Analysis data. Honey Suckle and Fescue are not included in this list.

Chinese (Ligustrum sinense), European (Ligustrum vulgare) and Japanese (Ligustrum japonicum) privets are all listed as invasive-exotic species that threaten native South Carolina forests. These are semi-evergreen, multi-stemmed shrubs or small trees that can grow up to a height of 20 feet. Ligustrum sp. are native to China, parts of Europe and Japan, and were first introduced into the United States around 1909 for ornamental use as shrub borders, erosion control plantings and wildlife forage. Characteristic flowers of Ligustrum species are showy, panicles of tiny, creamy-white flowers that are very fragrant and abundant in late spring through summer. Fruit produced are small, rounded dark-purple berries that persist throughout the winter, especially favored by birds.
