Control and Management

Invasive species can harm ecosystems, increase wildfires, damage forests, and outcompete native species. The US Geological Survey's Southwest Biological Science Center conducts research that provides our federal and state partners, cooperators and land managers with the tools, data and strategies to enhance biosecurity management.

The goal of this project is to address the threat of invasive Grass Carp by developing a comprehensive understanding of seasonal movements, habitat use, and areas of aggregation to determine when and where eradication efforts would be most effective.

The USGS National Wildlife Health Center (NWHC) conducts surveillance in wild birds to facilitate early detection and situational awareness for high consequence pathogens, including highly pathogenic avian influenza (HPAI) viruses.

INHABIT is a desktop-optimized web application and decision support tool with mapped and tabular summaries of habitat suitability models for over two hundred fifty terrestrial invasive plant species of management concern across the contiguous United States. It is the product of a scientist-practitioner partnership and is designed to facilitate enhanced invasive species management actions...

Invasive annual grasses can replace native vegetation and alter fire behavior, impacting a range of habitats and species. A team of researchers from the U.S. Geological Survey, Colorado State University, the Bureau of Land Management, and the U.S. Fish and Wildlife Service are working to identify factors that influence changes in the distribution and abundance of invasive annual grasses (IAGs)...

In the Upper Colorado River Basin, smallmouth bass ( Micropterus dolomieu) are considered the greatest threat to native fishes and have been linked to declines in federally protected humpback chub ( Gila cypha), including one population that was rapidly extirpated in the past. Long-term management efforts have been underway to remove smallmouth bass from rivers in the Upper Basin, but smallmouth...

Siren: the National Early Detection and Rapid Response (EDRR) Information System is an online resource for invasive species information sharing and collaboration that serves as the information hub of the National EDRR Framework.

Climate change-induced warming can alter plant phenology and disrupt ecosystems like the sagebrush steppe in western North America. The invasive annual grass cheatgrass can thrive under these altered conditions, exacerbating wildfires and threatening wildlife habitat, carbon storage, and other important ecosystem services. We are studying how different densities of cheatgrass respond to increased...

This project analyzes on-the-ground plant monitoring data across sagebrush and rangeland ecosystems to examine how fire, climate, topography, and plant communities influence the success of invasive annual grasses after fires.

Cheatgrass, an invasive annual grass, reduces ecosystem productivity, negatively impacts biodiversity, and is increasingly problematic in higher elevation ecosystems with climate change. Cheatgrass phenology (that is, the timing of yearly growth and lifespan) varies greatly with elevation, climate, and weather from year to year, which can make management planning difficult and reduce the ability...

The coronavirus pandemic, Chronic Wasting Disease (CWD) in white-tailed deer, and white-nose syndrome in bats have spawned great interest in diseases of native fish and wildlife. Many aspects of widely known diseases of wild (as opposed to domestic) animal populations are poorly understood, including their ecology, incidence, distribution, and methods for reducing effects of disease on culturally...

Sixteen years after Pd, the fungus that causes white-nose syndrome in bats, was first recognized in New York, its range now extends to the Rocky Mountains, and it has been definitively detected in all but seven states (Alaska, Arizona, Florida, Hawaii, Nevada, Oregon, and Utah). The National Wildlife Health Center and our partners continue to field test a WNS vaccine for wild bats and to research...
