通过文献综述，总结了美国16种主要入侵植物对牧场和荒地造成的环境、经济和社会损失。文献综述的结果表明，发表的信息范围从狭窄到全面。广泛的量化信息是由多叶大戟，绒毛雀麦，盐雪松，紫色金钱草，和几个矢车菊或星蓟所造成的环境影响公布。对于其他物种，数量信息有限，关于影响的参考主要是轶事或观察。大多数物种的经济影响没有得到充分的记录。在州或地区基础上进行的全面经济分析发表了关于多叶大戟，盐雪松和矢车菊。农业成本，包括放牧价值的损失进行了量化的几个额外的物种，但环境和社会成本不包括在分析。需要更多的研究来量化牧场和荒地上入侵的外来植物的经济和环境损失。
A literature review was conducted to summarize information on environmental, economic, and societal losses caused by 16 key invasive plants on rangeland and wildlands in the United States. Results of the literature review indicated that scope of published information ranged from narrow to comprehensive. Extensive quantitative information is published about environmental impacts caused by leafy spurge, downy brome, saltcedar, purple loosestrife, and several knapweeds or starthistle. For other species, quantitative information was limited and references to impacts were mainly anecdotal or observational. The economic impacts of most species were poorly documented. Comprehensive economic analyses conducted on either a state or regional basis were published about leafy spurge, saltcedar, and the knapweeds. Agricultural costs including loss of grazing value were quantified for several additional species, but environmental and societal costs were not included in the analyses. Additional research is needed to quantify economic and environmental losses of invasive nonnative plants on rangeland and wildland sites.
