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...

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 Brown Treesnake Laboratory - Guam

USGS scientists and staff associated with the Brown Treesnake Project are co-located at the Guam National Wildlife Refuge at the northern end of Guam in the western Pacific Ocean. Project staff work on developing and testing control tools for invasive brown treesnakes, as well as understanding their impacts on Guam's ecosystems. Project staff also lead the multi-agency Brown Treesnake Rapid...

Landscape and Habitat Assessment

A central focus of this program is to conduct multi-scale assessments in order to develop related geospatial decision-support tools and methods. The program includes synthesizing broad-scale datasets and developing innovative approaches to assess the vulnerability and resilience of wildlife habitats and ecosystems, relative to land management decisions and ecosystem stressors on Department of the...

Investigating Prey of Burmese Pythons using eDNA Methods

Environmental DNA (eDNA) is organismal DNA that can be found in the environment. Environmental DNA originates from cellular material shed by organisms (via skin, excrement, etc.) into aquatic or terrestrial environments that can be sampled and monitored using new molecular methods. Such methodology is important for the early detection of invasive species as well as the detection of rare and...

Control and Landscape-Scale Suppression of the Invasive Brown Treesnake

The Brown Treesnake is a highly destructive reptile species that has extirpated many native species of birds, bats, and lizards from the U.S. Territory of Guam. For more than two decades branch scientists with the Invasive Reptile Project have developed, validated, and tested the feasibility of Brown Treesnake control and suppression at various spatial scales.

Cruising to Improve the Detection of Burmese Pythons in Everglades National Park

It is not uncommon to see researchers cruising around Everglades National Park (ENP) on what has been a routine basis for the past ten months. Every evening, interns pack into a Chevy Volt for their shift assisting the U.S. Geological Survey in conducting Burmese Python (Python molurus bivittatus) nighttime surveillance through observational surveys. This effort to detect non-native snakes, namely...
