These plants spread outside the garden because birds eat the berries and then spread the seeds as they move about and do what birds do. U.S. Habitat: Temperate regions in the Southern states, and California.  For example, Chinese privet increases the decomposition rate of leaf litter by 2.6-fold in riparian forests. Chinese privet is a major invasive shrub within riparian zones throughout the southeastern United States. The Act requires everyone to take all reasonable and practical steps to minimise the risks associated with invasive plants and animals under their control. Trunks usually occur … Colonize by root sprouts and spread widely by abundant bird- and other animal-dispersed seeds. Its leaves are opposite, have smooth margins, and can vary in shape from oval to oblong. Chinese privet Ligustrum sinense Lour. (1.3 cm) long. (2011).  Although tolerant of varying soil and light conditions, including a tolerance for shade, privet survives best in mesic soil with abundant sunlight. (0.5 to 1.5 cm) wide. Japanese/Glossy and Chinese/European Privet Privet is commonly used as a hedge and is capable of invading natural areas such as floodplain forests and woodlands. Chinese privet is one of the most invasive shrubs in the southeastern United States - frequently growing in dense thickets along roadsides, on rights of way and in forests. Chinese privet (Ligustrum sinense) is one of several non-native, invasive plants that can be found on ANHC natural areas, as well as throughout the state of Arkansas. , Mechanical removal of privet, especially for younger plants or smaller areas of growth, can be effective; however, all of the root must be removed to prevent root re-sprouting. They ripen to dark purple to black and persist into winter.  Plots removed of privet resulted in four times as many bee species as control plots in which privet was not removed. Location, habitat, weather, and a variety of other conditions are factors that help determine the best treatment choice. (5 to 7.6 cm) long.  Prior to privet invasion much of the native land was clear and open; currently, privet forms a dense thicket which chokes out other, usually native, plant life.  When introduced to an ecosystem, privet grows quickly and, given time, will produce a thick layer under the forest canopy preventing sunlight from reaching the native plants below. This invasive species can be identified by looking for the characteristics described in the paragraphs that follow. Description. Identification and biology of non-native plants in Florida's natural areas. Gavier-Pizarro, G.I., T. Kuemmerle, L.E. This is called a general biosecurity obligation (GBO).  Out of approximately twenty plants per species, only single individuals of Acer negundo, Chamaenerion latifolium and C. tribuloides survived the entire study when in the presence of Chinese privet. , The foliar treatments are most effective against dense thickets of privet. This will prevent the spread of the privet but will not eradicate it. Hanula, J. L., Horn, S. (2011). Japanese/Glossy privet (L. lucidum)  Privet is monitored by the US Forest Service's Invasive Species Program while the National Park Service deploys Exotic Plant Management Teams. , Insects are greatly affected by the proliferation of invasive species such as privet.
