To be invasive, a species must adapt to the new area easily. Many wild plant species could make important contributions to human food supplies, either as new crops or as a source of genetic material to provide disease resistance or other desirable traits to current domestic crops. As the population and range of the species decreases, the species becomes more threatened.1) Population reduction rateA species is classified as vulnerable if its population has declined between 30 and 50 percent.
