Invasive grassland‐rangeland plants of China and the United States of America
Alien invasive plants can transform biotic communities and interfere with ecological processes.Invasive plants in the 17 western United States are estimated to cover 53.8 million ha with an expansion rate of 680,000 ha per year.Similar information for the grasslands of China was not found.Total cost of invasive plants in the USA has been estimated at ＄ 40 billion per year, while total economic loss from invasive organisms in China has been given at ＄ 14.5 billion.The commonality of climate, floral and faunal affinity and increasing commerce and travel between the China and North America and other entities provides for high potential for biotic invasions to what many consider pristine grazing lands.It is suggested that a survey for invasive species in China grasslands be initiated.A general invasive species management plan would include : prevention, early detection and rapid response, control techniques and restoration of invaded sites.
