Invasive Species
Invasive Species
An invasive species is an introduced species that has established itself and causes negative impacts to the native environment, the economy, and even human health. WARC science is used by resource managers to help mitigate and control these problematic species, including the Burmese python, the Cuban treefrog, and invasive carp.

Asian Tiger Shrimp Distribution and Genetics
The Asian tiger shrimp began appearing in commercial shrimp catches in 2006. They grow larger than native shrimp and are known to be fierce predators - so shrimpers and managers are concerned about the potential effects this species might have.
Non-native Marine Fishes: Tracking Distributions with the USGS Nonindigenous Aquatic Species Database
WARC scientists work with local partners to verify and document sightings of non-native marine fishes.
Assessing Risk Communication in the Pet and Aquarium Trade: An Analysis of Outreach and Engagement Efforts
WARC researchers evaluated whether outreach campaigns targeting pet owners are effectively reaching their desired audiences, namely pet owners who might unintentionally or purposefully release their pet into the wild.
Future Aquatic Invaders of the Northeast U.S.: How Climate Change, Human Vectors, and Natural History Could Bring Southern and Western Species North
Researchers will evaluate the potential of aquatic species to invade the Northeast U.S. Following the identification of appropriate target species by regional stakeholders, researchers will gather data from the NAS database and develop models to determine habitat suitability for each species.
Multi-year Burmese Python Vital Rate Research Collaborative in the Greater Everglades
USGS researchers will track juvenile Burmese python within Big Cypress National Preserve (BICY) and collect data on snake growth, habitat use, and causes of mortality. Known-fate models will be used to estimate survival and better understand factors that influence survival.
Fish Slam December 2023
Fifty-four biologists from nine organizations, including USGS, participated in a two-day Fish Slam event on December 13 - 14, 2023 in Southwest Florida.
Purple Loosestrife in Louisiana: A Call for Citizen Scientists
Join USGS in helping to prevent the spread of the invasive purple loosestrife in Louisiana.
Fish Chat and Slam December 2022
Fifty-seven fish biologists from 12 organizations participated in a three-day Fish Chat and Slam event in South Florida.
USGS Coordinated Burmese Python Research Strategy for South Florida (FY21 – FY27)
Wetland and Aquatic Research Center and Fort Collins Science Center are coordinating a long-term, landscape-scale Burmese python research strategy for South Florida.
Across Trophic Level System Simulation (ATLSS) Program for the Greater Everglades
Goals of the ATLSS Program are to help achieve a better understanding of components of the Everglades ecosystem, to provide an integrative tool for empirical studies, and to apply these tools to an adaptive management framework.
Virtual Fish Slam - March 2021
In March 2021, USGS researchers and partners conducted the first-ever Virtual Fish Slam. The bi-annual Fish Slam event helps monitor new introductions and document range expansion of known non-native freshwater fishes.
Monitoring and Removal of Invasive Cuban Treefrogs (Osteopilus septentrionalis) on the Gulf Coast
WARC researchers are performing visual encounter surveys and passively capturing Cuban treefrogs to remove as many of the invasive anurans as possible.
