An invasive species is an introduced species that harms its new environment. [2] Invasive species adversely affect habitats and bioregions , causing ecological, environmental, and/or economic damage.
Privets are any of a number of shrubs or trees in the genus Ligustrum, many of which are invasive. The genus contains about 50 species [1] native to the Old World and Australasia. [2] Many members of the genus are grown as ornamental plants in parts of the world. Several species of privet have become a nuisance in regions outside their ranges.

[1] The level of vulnerability of a habitat to invasions from outside species is defined as its invasibility.
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
The only species that feeds on purple loosestrife is the galerucella beetle, which devour the plants and then die off after their food source is gone, eliminating the risk of the beetles becoming ...
