Interpretive Summary: Surveys for invasive species within natural environments are essential to monitoring spread and devising management strategies of these unwanted, often destructive organisms. New technologies allow the improvement of such surveys through the detection of invasive species DNA within the environment, e.g. from shed skin cells or faeces. Such sampling of environmental DNA, or eDNA, for the indirect detection of invasive species has proven to be effective and of great value to land managers and regulators charged with managing invasive species. However, many such regulators have been hesitant to adopt eDNA methods and data, likely due to lack of experience with or understanding of the technology and its potential benefits. This manuscript provides comprehensive information on all aspects of the utilization of eDNA protocols with a focus on their utility to invasive species management, written with a target audience of federal, state, and local government regulators.
Technical Abstract: Invasive species surveillance programs can utilize environmental DNA sampling and analysis to provide information on the presence of invasive species. Wider utilization of eDNA techniques for invasive species surveillance may be warranted. This paper covers topics directed towards invasive species managers and eDNA practitioners working at the intersection of eDNA techniques and invasive species surveillance. It provides background information on the utility of eDNA for invasive species management and points to various examples of its use across federal and international programs. It provides information on 1) why an invasive species manager should consider using eDNA, 2) deciding if eDNA can help with the manager’s surveillance needs, 3) important components to operational implementation, and 4) a high-level overview of the technical steps necessary for eDNA analysis. The goal of this paper is to assist invasive species managers in deciding if, when, and how to use eDNA for surveillance. If eDNA use is elected, the paper provides guidance on steps to ensure a clear understanding of the strengths and limitation of the methods and how results can be best utilized in the context of invasive species surveillance.
