Early detection and rapid response tools for invasive tegu lizards
Scientists at USGS have shown that much of the US is suitable for invasion by tegu lizards, and suitability will likely increase in the future. While tegus can be removed via trapping, it is difficult to monitor every geographic area where tegus could invade. Thus, methods for quickly detecting and removing tegus in new areas are the best way to prevent spread and minimize damage from these...
Developing and evaluating a point-of-use environmental DNA test for rapid field detection of highly invasive brown treesnakes
New terrestrial environmental DNA (eDNA) sampling techniques are sensitive tools for early detection of the highly invasive brown treesnakes (BTS). In a new collaborative research effort involving four USGS science centers, scientists have initiated the development of an innovative point-of-use (POU) assay for BTS. POU assays are tests that can be run in the field with minimal equipment and no...
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.
Python Vital Rates
Researchers from USGS-FORT and WARC and University of Florida are collaborating on a long-term Burmese python research program in southern Florida to address management needs of partners and stakeholders throughout the Greater Everglades.
State Partnerships in South Florida
USGS-FORT in partnership with the University of Florida and two state agencies (South Florida Water Management District and Florida Fish and Wildlife Conservation Commission) have initiated a scout snake program to increase the ability to detect and remove Burmese pythons from the interior of the landscape.
Biology, Impacts and Control of Invasive Reptiles in the Everglades
Invasive species are considered to be second only to habitat degradation in terms of negative impacts on the Earth’s ecosystems, and our scientists make up a significant proportion of the global expertise in the rapidly-growing problem of invasive reptiles.
USGS Everglades Research Office - Florida
The Daniel Beard Center in Everglades National Park provides the base for most of the field work done on the control of invasive reptiles by USGS Fort Collins Science Center staff. The team works in Everglades National Park, Big Cypress National Preserve, Crocodile Lake National Wildlife Refuge, and other parts of the Greater Everglades Ecosystem focusing on, among other species of concern...
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.
Biology, Impacts and Control of Invasive Reptiles in the Pacific
Research on Guam has led to development and validation of numerous effective control tools, including the advancement of reptile control to support native species recovery.
Informing Habitat Management for Desert Tortoise
There is increasing support for adopting landscape approaches to resource management, including monitoring threats that affect multiple resources across broad extents. However, there remains a need to assess potential threats to individual species of conservation concern. USGS is evaluating the extent to which a generalized indicator of terrestrial development can be used to inform and evaluate...
