Threat Forecasting and Decision Support

USGS research focuses on developing and enhancing capabilities to forecast and predict invasive species establishment and spread. Early detection helps resource managers identify and report new invasive species, especially for cryptic species and those in very low abundance, to better assess risks to natural areas. Tracking the establishment and spread of existing and new invasive species is critical to effectively manage invasive species.

USGS Scientists Meet with Cuban Government Officials about Invasive Species

Everglades-based biologists Dr. Bryan Falk and Michelle Collier met with a group of natural resource professionals from the Government of Cuba on January 28, 2016, to brief them about the biology and impacts of invasive reptiles.

Developing Ecological Forecasting Models

USGS Fort Collins Science Center recently created the Resource for Advanced Modeling (RAM), where scientists are exploring the latest in predictive modeling techniques, including determination of which techniques work better with different datasets, taxa, and spatial extents and resolutions.


Spatial variation in risk and consequence of Batrachochytrium salamandrivorans introduction in the USA

Using characteristics of Bsal ecology, spatial data on imports and pet trade establishments, and salamander species diversity, we identify high-risk areas with both a high likelihood of introduction and severe consequences for local salamanders.

Ecosystem impacts of exotic annual invaders in the Genus Bromus

An understanding of the impacts of exotic plant species on ecosystems is necessary to justify and guide efforts to limit their spread, restore natives, and plan for conservation.

Brumation of introduced Black and White Tegus, Tupinambis merianae (Squamata: Teiidae), in southern Florida

An established population of Tupinambis merianae (Black and White Tegu) in southeastern Florida threatens the Everglades ecosystem. Understanding the behavioral ecology of Black and White Tegus could aid in management and control plans.
