Invasive Species
Invasive Species
USGS WARC science focuses on better understanding invasive species' biology and ecology and their potential for negative ecological, economic, or health impacts. WARC implements innovative approaches to help monitor the spread of invasive or non-native species, develop new methods and technologies to better detect such species, and assess their impact to the native ecosystems they have invaded.

Diet and Reproductive Phenology in a Recently Established Population of Invasive Cuban Treefrogs (Osteopilus septentrionalis)
WARC researchers are exploring relationships between body size, time of year, sex, and reproductive development to better understand the reproductive phenology of the New Orleans population of Cuban treefrogs compared to Florida populations.
Fish Chat and Slam November 2019
Fifty fish biologists from 15 organizations participated in a three-day Fish Chat and Slam event in South Florida on November 5-7, 2019.
Using Unmanned Aerial Systems (UAS) Capabilities to Help Identify Giant Salvinia (Salvinia molesta) and the effects of Salvinia weevil (Cyrtogagous salviniae)
USGS is collecting remotely sensed data to classify Salvinia molesta, a non-native aquatic species that reduces light and oxygen levels in water, making it unsuitable for fish and other aquatic plant life.
Applications of Advanced Tracking and Modeling Tools with Burmese Pythons across South Florida's Landscape
Researchers will determine movement rates and habitat-use patterns of pythons across the South Florida landscape by conducting a telemetry study tracking pythons simultaneously in several locations
Habitat Selection of the Burmese Python in the Florida Everglades
Researchers plotted locations of radio-tagged pythons to create a habitat suitability model.
Comparative Freshwater Fish Toxicity Testing of Antimycin A
Researchers are investigating the influence of Antimycin A on invasive carp and non-target fishes by measuring the effects of a novel species-specific bait formulation.
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.
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.
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.
Integrating Science and Management for Optimal Prevention and Control of Invasive Nymphoides in Florida
Two invasive species of floating hearts, Nymphoides cristata and N. indica, are actively managed in Florida. A rare native species, N. humboldtiana, has been found in Florida and verified by molecular methods; this species is nearly indistinguishable from N. indica.
