Invasive Species Management

Nontidal Wetland & Stream Mitigation Sites


The objective of this project is to study invasive, nuisance, and undesirable (INU) plant management in both uplands and wetlands restoration areas along a restored stream (Northern Virginia Stream Restoration Bank in Reston, VA) using a random block research design (or similar layout) in which several different management approaches will be implemented in a controlled field setting. Methods will include (but not be limited to) traditional herbicide treatment, cultural practices (e.g., strategic plantings, soil amendments, etc.), and mechanical removal techniques. The eventual study design, as well as the specific methods chosen, will be informed by a comprehensive literature review that will be conducted at the outset of the study, as well as an INU species inventory throughout the study area. This phase of the project will also derive from the results of recent research on invasive species in compensatory mitigation conducted by PI Doug DeBerry under RPG grant RFP #08. The College of William and Mary, in association with Virginia Tech and George Mason University, is leading this project.

Results from this research program will be directed at filling important information gaps in INU species management on mitigation sites, including: 1) viable approaches for invasive species management that can be used effectively as alternatives to herbicide; 2) proactive management techniques that can be used to reduce risk of invasion during site development and establishment; and, 3) broadly applicable techniques that are effective for multiple invasive species – with its results presented in a format suitable for use by both regulations and practitioners of wetlands and stream restoration.
