ABSTRACT: In response to decades of invasions by non-native species and prompted by Great Lakes Restoration Initiative funding, the U. S. Fish & Wildlife Service is implementing a monitoring program focused on early detection of new non-native fishes, crustaceans and bivalves in lakes Erie, Huron and the other Laurentian Great Lakes. The goal of this program is to detect species while they are rare, potentially allowing initiation of management or policy efforts to stop new species from becoming invasive. Using vector- and species-based risk assessments as well as direct measures of relative risk for potential vectors of introduction, transparent procedures have been developed to select sampling sites where new species would likely first appear in the system. A suite of sampling gears is being used to collect a variety of organisms during various life stages. Rarefaction is performed to estimate species detection probability, and molecular techniques are used to improve organism detection and identification. The USFWS early detection monitoring program is designed to be flexible and responsive to new non-native species threats.
