  • CHINESE PRIVET Due to Its Ability to Successfully Compete with And
    Plant Guide by this species is large-scale ecosystem modification CHINESE PRIVET due to its ability to successfully compete with and Ligustrum sinense Lour. displace native vegetation. Chinese privet plants Plant Symbol = LISI mature rapidly and are prolific seed producers. They also reproduce vegetatively by means of root suckers. Contributed by: USDA NRCS National Plant Data Once established, Chinese privet is difficult to Center & Louisiana State University-Plant Science; eradicate because of its reproductive capacity. partial funding from the US Geological Survey and the US National Biological Information Impact/Vectors: Ligustrum sinense is native to China Infrastructure and was introduced into the United States in 1852 for use as an ornamental shrub. It is used for hedge and mass plantings, and sometimes as single specimens for its foliage and its profusion of small white flowers (Dirr 1990; Wyman 1973). It continues to be widely sold in the nursery and gardening industry. The foliage of Chinese privet is also used, presumably, for cut-flower arrangements. This horticultural introduction has been cultivated for a relatively long time in the United States. Wyman (1973) reports that this species is still growing as a hedge on the old Berkman’s Nursery grounds in Augusta, Georgia, where it was planted in the early 1860’s. It was planted on the Chickamauga and Chattanooga National Military Park after it came under the control of the Secretary of War in 1890. Present day plants are descendants of those early plantings (Faulkner et al. 1989). According to Small (1933), the species was escaping from cultivation in southern Louisiana by the 1930’s.

  • Taxonomic Overview of Ligustrum (Oleaceae) Naturalizaed in North America North of Mexico
    Phytologia (December 2009) 91(3) 467 TAXONOMIC OVERVIEW OF LIGUSTRUM (OLEACEAE) NATURALIZAED IN NORTH AMERICA NORTH OF MEXICO Guy L. Nesom 2925 Hartwood Drive Fort Worth, TX 76109, USA www.guynesom.com ABSTRACT A key, morphological descriptions, and basic synonymy are provided for the eight species of Ligustrum known to be naturalized in North America north of Mexico: L. japonicum, L. lucidum, L. obtusifolium (including L. amurense), L. ovalifolium, L. quihoui, L. sinense, L. tschonoskii, and L. vulgare. Identifications have been inconsistent particularly between L. sinense and L. vulgare and between L. japonicum and L. lucidum. The occurrence of L. quihoui outside of cultivation in Arkansas, Mississippi, and Oklahoma is documented. Phytologia 91(3): 467-482 (December, 2009). KEY WORDS: Ligustrum, Oleaceae, North America, naturalized, taxonomy The lustrous, mostly evergreen leaves and masses of white, fragrant flowers make privets popular for landscaping and hedges. Many of the species, however, have become naturalized in the USA and Canada and already have proved to be destructive colonizers, especially in the Southeast. Among the naturalized species, European privet (Ligustrum vulgare) is native to Europe and northern Africa; all the rest are native to Asia, mainly China, Japan, and Korea. Many new species and varieties of Ligustrum have been described since overviews of Koehne (1904), Lingelsheim (1920), and Mansfield (1924). The genus in eastern Asia has recently been studied by Chang & Miao (1986), and Qin (2009) has provided a taxonomic overview of the whole genus that recognizes 37 species - divided into five sections based primarily on fruit and seed morphology. In Qin’s arrangement, among the North American species, sect.

  • Identification and Control of Invasive Privets (Ligustrum Spp.) in the Middle Southern United States
    Invasive Plant Science and Management 2010 3:482–488 Notes and Commentary Identification and Control of Invasive Privets (Ligustrum spp.) in the Middle Southern United States Victor Maddox, John Byrd, Jr., and Brett Serviss* The identification of privet in the middle southern United States can be difficult. Because most introduced species of privet can be invasive, and recent mapping projects seek location and species population data, proper identification is important. Without proper identification of privet species, data on species distributions and other pertinent information regarding invasiveness could lead to improper conclusions. Currently, information on privet identification is scattered throughout a number of reference materials. The purpose of this publication is to assist with the proper identification of escaped privet species, and suggest management options.

  • Ligustrum Vulgare)
    Genetic, Age, and Spatial Structure to Improve Management of Common Privet (Ligustrum vulgare) THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Wanying Zhao Graduate Program in Horticulture and Crop Science The Ohio State University 2012 Master's Examination Committee: John Cardina, Advisor Andy Michel Charles Goebel Copyrighted by Wanying Zhao 2012 Abstract Invasive plants that spread through natural areas are likely to threaten sensitive and unique habitats. Since it is impossible to kill every individual invasive plant, managers need landscape-scale strategies to direct management efforts along invasion sites and corridors of spread. Therefore, managers need information of how invasive plants spread over time and space with respect to sensitive habitats. Ligustrum vulgare L. (common privet) is a woody invasive plant that is spreading to sensitive habitats in eastern North America. To assist in developing efficient management approaches for this species, we studied the spatial genetic structure of L. vulgare across the landscape within the 325-acre Wooster Memorial Park (WMP) and in three states, using sequences from two chloroplast DNA (cpDNA) genes. For samples taken within the park, we combined patch age, spatial features, and genetic data to reconstruct invasion history and analyze spatial distribution patterns. We conducted a comprehensive survey in the park, mapping and sampling established stands of L. vulgare. Ages of 331 patches in WMP were determined by examining tree-rings. DNA was extracted from samples taken from eight sites in Ohio and two adjacent states along with 313 samples from WMP.

The paper is concerned with the results of the ruderal flora investigation carried out in the vicinity of the town of Kosovska Mitrovica (Serbia) and its surroundings, in different urban and suburban habitats, and is based on the copious floristic researches conducted between 1995 and 1996 and repeated in 2016. The total number of 444 taxa was reported in the course of 2016. Not only was reported the presence of 386 taxa in the same areas between 1995 and 1996, but also 58 new taxa were recorded in recent field explorations. The ruderal flora composition in Kosovska Mitrovica area has changed by 13.06% in the past 20 years. Detailed taxonomic, ecological, and phyto-geographical analyses were provided for the discovered synanthropic flora. Special attention was paid to the appearance of new invasive species unregistered 20 years ago, but which, due to the more intensive anthropogenic influence, have become more diverse in number and frequency in the investigated areas.

  • Does Topography Affect the Colonization of Lonicera Maackii and Ligustrum Vulgare in a Forested Glen in Southwestern Ohio?1
    Does Topography Affect the Colonization of Lonicera maackii and Ligustrum vulgare in a Forested Glen in Southwestern Ohio?1 ANN GAYEK AND MARTIN F. QUIGLEY, Department of Horticulture and Crop Science, The Ohio State University, Columbus, OH 43210-1086 ABSTRACT. Lonicera maackii (Amur honeysuckle) and Ligustrum vulgare (Common privet) are two exotic shrubs that have naturalized throughout the eastern and midwestern United States. This study examines the influence of topography on the level of invasion of Lonicera maackii and Ligustrum vulgare in a second growth forested glen in southwestern Ohio (Glen Helen, Yellow Springs, OH). The topographic positions compared were east-facing slope, bottomland, and west-facing slope using twelve 100 m transects through each of the three habitats for a total of 36 transects. L. maackii andZ. vulgare plants were counted in ten 3 x 3 m quadrats along each transect for a total of 120 quadrats per topographic position. Two-way analysis of variance compared interaction between topography and numbers of plants in three size classes (small, medium, large). Average density of L. maackii for all size classes was 1136 plants/ha. East-facing slopes were most heavily invaded with 497 plants/ha; there were 238/ha in the bottomland; 401/ha on the west-facing slopes. East- facing slopes are close to town, one of the original sources of seed. West-facing slopes are surrounded by farmland, fence rows, and farmhouses, a second source of seed. West-facing slopes have significantly fewer large L. maackii and L. vulgare than east- facing slopes but it may only be a matter of time until they are as heavily colonized as the east-facing.
