Invasive plant conundrum: What makes the aliens so successful?

Eric J. Holzmueller, Shibu Jose

Abstract


Invasive alien plants have caused extensive economic and ecological damage throughout the world. Not all plant species, however, become invasive outside of their native range. The challenge for land managers and policy makers is to determine what species are most likely to become invasive so that control efforts can be initiated before the alien species becomes widespread. A description of plant characteristics and multiple hypotheses that explain invasibility of some of the world’s worst invasive species are provided in this review. Failure to control invasive plants will continue to lead to decreased agricultural production and ecosystem degradation. Control of invasive plants is a daunting task, and will only be accomplished with coordinated efforts of all countries.
