Invasive Species

Research, monitoring, and technology development for containment or eradication of non-indigenous species that have potential to cause significant ecologic or economic damage and those that impact human health. Scientists test and develop methods to better detect invasive species, determine the likelihood of their spread and impact, report distribution to track their spread, methods to contain and control harmful invasive species, as well as means to restore ecosystems after control efforts. Recent emphasis has been on using advanced technologies such as remote sensing and genetics methods to develop species-specific detection and control tools for terrestrial and aquatic species, with recent focus on Asian carp, sea lamprey, and snakes. Includes studies on ecologic impacts, invasion biology, and basic life history to help determine risk and develop control strategies.

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.

Survey and Assessment of Live Food Markets as an Invasion Pathway

Live food markets may be a source of the increasing number of non-native wild invertebrate and fish species, like Asian swamp eels and snakeheads. USGS is surveying such markets around the United States to identify and document species that might be of concern if released live into the wild to assess if the live food market is a possible invasion pathway.

The Nonindigenous Aquatic Species Alert Risk Mapper (ARM)

The Nonindigenous Aquatic Species (NAS) program has developed a new tool, the NAS Alert Risk Mapper (ARM), to characterize waterbodies in the conterminous U.S. and Hawaii at potential risk of invasion from a new nonindigenous species sighting.

The Nonindigenous Aquatic Species Flood and Storm Tracker (FaST)

Storm-related flooding can lead to the potential spread of nonindigenous (or non-native) aquatic species into waterways they have not been seen in before. The USGS Nonindigenous Aquatic Species program has developed an innovative mapping tool to help natural resource managers with post-storm nonindigenous aquatic species detection and assessment efforts.

Fish Slam November 2018

In November 2018, USGS researchers joined partners in South 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.

Effects of Native and Non-native Fishes on Native Apple Snail Population Dynamics

The Florida apple snail is a critical component of the state's wetland food webs. USGS scientists assess the effects of native and non-native fishes on the native snail populations.

Development of a Quantitative Risk Assessment Tool to Predict Invasiveness of Non-native Freshwater Fishes in Everglades National Park

The introduction of non-native fishes is a problem across the United States, particularly in Florida. USGS scientists are developing a decision support tool to help natural resourece managers prioritize which species to focus prevention, detection, rapid response, and control efforts.

Risk Analysis of Invasive Freshwater Fishes in Hawaii and Micronesia

Invasive species threaten biodiversity around the world, especially on islands. USGS scientists are helping to identify fish species that have the greatest potential to invade the fresh waters of Microneisa.
