PURPOSE The U.S. Army Engineer Research and Development Center ERDC, Environmental Laboratory EL developed this technical note to describe invasive woody trees and shrubs that negatively affect USACE riparian management and restoration activities. The USACE Ecosystem Management and Restoration Research Program EMRRP is supporting a nationwide effort to address the impacts of invasive woody plant species on ecosystem restoration, and more specifically, to determine mechanisms to address the most prevalent invasive species by region that impact restoration activities. This large research program has four objectives 1 identify the group of invasive woody riparian plants that are most problematic to USACE ecosystem restoration efforts 2 develop resource guidelines that suggest time and location thresholds in which funds should be spent to control invasive woody plants 3 determine the most efficient and ecologically-effective spatial configuration for woody invasive riparian plant removal on Corps-managed lands and 4 investigate how faunal communities respond to various spatial control methods for woody invasive plant removal in densely vegetated riparian habitats.
