Invasive Species Program

Early Detection and Rapid Response

While invasive species prevention is the first line of defense, even the best prevention efforts will not stop all invasive species. Early Detection and Rapid Response (EDRR) is defined as a coordinated set of actions to find and eradicate potential invasive species in a specific location before they spread and cause harm. USGS activities that support EDRR span the geography of the country and address organisms and pathways most appropriate to address the needs of our partners. USGS provides scientific support to DOI Bureaus and other partners to aid in implementation of EDRR efforts and inform management actions. In certain cases, USGS leads multi-agency / partner rapid response efforts where specific skill sets are required.

Statistical Models for the Design and Analysis of Environmental DNA (eDNA) Surveys of Invasive and Imperiled Species

Detecting invasive species at low densities or prior to population establishment is critical for successful control and eradication. For example, Burmese pythons occupy thousands of square kilometers of mostly inaccessible habitats.

Efficacy of eDNA as an Early Detection and Rapid Response Indicator for Burmese Pythons in the Northern Greater Everglades Ecosystem

Traditional approaches to locating Burmese pythons - including visual searches and trapping - have resulted in low detection. Environmental DNA - or eDNA - is increasingly being used to detect the presence of non-native species, particularly when traditional methods may not be adequate.
