Control Strategies for the Invasive Reed Canarygrass (Phalaris arundinacea L.) in North American Wetlands: the Need for an Integrated Management Plan

Abstract

Abstract Phalaris arundinacea L. (reed canarygrass) is one of the most noxious invasive species in North American wetlands, rivers, and lakes. As is true for many invasive species, detailed research may give insights into the ecological and evolutionary factors that promote reed canarygrass invasion. However, important insights into control strategies of reed canarygrass may be gleaned from a synthesis of all the relevant ecological and management studies. We assessed the control strategies previously applied to contain reed canarygrass invasions, the potential for new promising strategies, and the research that is still needed to improve its control in North America. We showed that no one method is sufficient, and that the most successful strategies require both physical and chemical methods, coupled with hydrological management. Moreover, subsequent restoration of the community structure and composition is needed to limit new infestations of reed canarygrass or other invaders. Biological control has not...
