一般影响
Tu(2000)报告说：柔枝莠竹(Microstegium vimineum)能够侵入荒地田野并迅速用几乎单一种的植群取代自然族群。它通常会缓慢的入侵未受干扰的地区，但会迅速填满受干扰的田野，如洪水冲刷的溪畔和每年割草一次的道路沿线。一旦建立族群，柔枝莠竹(Microstegium vimineum)能在3至5年内排挤掉森林湿地内的本地草本植被(亨特, 1992;巴登, 1987，in Tu, 2000)。此外，柔枝莠竹(Microstegium vimineum)可能会改变自然土壤条件，替许多本地物种，创造一个荒凉的环境。这些已被柔枝莠竹(Microstegium vimineum)入侵的地区，植物残骸和土层有机层都变薄，相较于未受入侵的地区，入侵区土壤的pH值显著高于未受入侵的地方(Kourtev等人, 1998，Tu 2000)。没有任何迹象显示柔枝莠竹(Microstegium vimineum)会产生植物相克物质(Woods, 1989，in Tu, 2000)。柔枝莠竹(Microstegium vimineum)植群会侵占鹌鹑和其它野生动物高质量的筑巢栖地。此外，它创造良好的栖息地给老鼠，特别是棉大鼠(Sigmodon spp.)，棉大鼠常会捕食巢中的本土美洲鹑(Colinus virginianus)，并吸引其它掠食者(A. Houston，pers。comm.，in Tu, 2000)。 柔枝莠竹(Microstegium vimineum)似乎也能够改变土壤机能，提高pH值和减少氮含量(埃伦费尔德等人, 2001)。Kourtev等人1999年发现柔枝莠竹(Microstegium vimineum)族群入侵的地方，都有高密度的外来(欧洲)蚯蚓，相较于附近未受入侵的土壤。
地点特有的影响：United States (USA) 
其它: Established populations of Microstegium vimineum usurp quality nesting habitat from wildlife (Tu, 2000).
改变营养机制: Microstegium vimineum may be responsible for altering natural soil conditions, creating an inhospitable environment for many native species. In areas that have been invaded by M. vimineum, both litter and organic soil horizons were thinner than in uninvaded areas, and the pH of soils in invaded sites was significantly higher than in uninvaded sites (Kourtev et al 1998, in Tu, 2000).
竞争: Tu (2000) reports that Microstegium vimineum is capable of invading wildland areas and swiftly replacing natural communities with nearly monospecific stands. Once established, M. vimineum is able to crowd out native herbaceous vegetation in wetlands and forests within three to five years (Hunt 1992, Barden 1987, in Tu, 2000).
