Invasive Snakes

An invasive species is an introduced species that has itself themselves and threatens the diversity and/or stability of a native species or environment. WARC researches the basic biology and environmental tolerances of these plant and animal species to provide resource managers with the ecological facts they need to help mitigate and control these problematic species. This work includes invasive snakes, like the Burmese python in South Florida.

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.

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.

Nonindigenous Aquatic Species (NAS) Program

Welcome to the Nonindigenous Aquatic Species (NAS) information resource for the United States Geological Survey. Located at Gainesville, Florida, this site has been established as a central repository for spatially referenced biogeographic accounts of introduced aquatic species. The program provides scientific reports, online/realtime queries, spatial data sets, distribution maps, and general...

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.

Genetic Analysis of the Invasive Burmese Python to Aid Management and Population-Control Decision-Making

Invasive Burmese pythons threaten the success of Everglades restoration efforts. To assist with management and population control decision making, USGS scientists are implementing genetic studies to identify potential new entry pathways and to help quantify the size of the breeding population.

Using Environmental DNA for Burmese Python Detection Probabilities and Range-Delimitation in Southern Florida

Current tools for detection of Burmese pythons in South Florida have resulted in low detection rates. Environmental DNA - eDNA - has shown to be effective at detecting these invasive snakes, and can help to determine range limits for the species, information that is critical for management and control efforts.

Ecology of and Control Strategies for Invasive Burmese Pythons (Python molurus bivitattus) in the Greater Everglades

Telemetry tracking of captured pythons reveals movement patterns of the invasive Burmese python in the Greater Everglades, information that managers can use to prioritize python control efforts.
