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.

Treasure Coast and Central Florida Fish Slams- 2019

In March and June 2019, USGS researchers joined partners in Treasure Coast and Central Florida where they sampled freshwater bodies for non-native fishes. The bi-annual Fish Slam event helps monitor new introductions and document range expansion of known non-native fishes.

Using Robots in the River: Biosurveillance at USGS streamgages

For more than a decade, researchers around the world have shown that sampling a water body and analyzing for DNA (a method known as eDNA) is an effective method to detect an organism in the water. The challenge is that finding organisms that are not very abundant requires a lot of samples to locate this needle in a haystack. Enter the "lab in a can", the water quality sampling and processing robot...

Cheatgrass and Medusahead

Invasive annual grasses, such as cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae), are one of the most significant stressors to rangeland ecosystems in the western U.S. Their expansion and dominance across this area are the most damaging ecosystem agents on this iconic landscape.

Early Detection Monitoring May Not Be Sufficient for Invasive Mussels in the Columbia River Basin

The ecological and economic costs of an invasive quagga or zebra mussel infestation in the Pacific Northwest of the U.S. would be significant. The development of invasive mussel monitoring programs in the Pacific Northwest provides a unique opportunity to evaluate a regional invasive species detection effort early in its development. Although efforts are underway to monitor for the presence of...

Invasive Species Tools

Tracking the establishment and spread of existing and new invasive species is critical to effectively manage invasive species. In addition to standard means of monitoring, the USGS is developing new tools, particularly molecular techniques, to assist in the early detection of invasive species.

Pathways for Movement and Rate of Spread of Rapid ‘Ōhi‘a Death on the Island of Hawai‘i

Rapid ‘Ōhi‘a Death (ROD) is an emerging and rapidly spreading disease of ‘ōhi‘a (Metrosideros polymorpha), a keystone native forest tree in the Hawaiian Islands. The disease is highly pathogenic in native ‘ōhi‘a and can lead to significant mortality once symptoms become evident. This emerging pathogen is a significant threat to native forests throughout the state because of its potential impacts...

Asian Carp Integrated Control and Containment

Increased threat of Asian carp entering the Great Lakes and spreading to other basins such as the Upper Mississippi River and Ohio River basins, has led to increased prevention and control efforts since 2010. Successful management of invasive species requires methods to contain future spread, reduce population levels, and minimize their effects. In collaboration with partners, USGS scientists have...

Environmental DNA (eDNA) Sampling Improves Occurrence and Detection Estimates of Invasive Burmese Pythons and Other Constrictor Snakes in Florida

Environmental DNA (eDNA) is organismal DNA that can be found in the environment. Environmental DNA originates from cellular material shed by organisms (via skin, excrement, etc.) into aquatic or terrestrial environments that can be sampled and monitored using new molecular methods. Such methodology is important for the early detection of invasive species as well as the detection of rare and...

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.
