INHABIT: A web tool for invasive plant management across the contiguous United States
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...
Effects of the herbicide, Indaziflam, on invasive annual grasses
Invasive annual grasses are spreading across the sagebrush ecosystem, threatening the survival of native plant species and the wildlife habitats they support. Researchers from the U.S. Geological Survey, Colorado State University, University of Wyoming, the Bureau of Land Management, National Park Service, and the U.S. Fish and Wildlife Service are collaboratively investigating the factors that...
Evaluating potential vectors of annual grass invasion
Invasive annual grasses, facilitated by a range of disturbances, are invading many areas within the sagebrush biome. Researchers from the U.S. Geological Survey, Colorado State University, U.S. Fish and Wildlife Service and the Bureau of Land Management are investigating which non-fire disturbances are most associated with the spread of invasive grasses. The findings from this study could guide...
Assessing the Proliferation, Connectivity, and Consequences of Invasive Fine Fuels on the Sagebrush Biome
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)...
Modeling chronic wasting disease prevalence through time to investigate mechanisms of spread in deer and elk in Wyoming
Diseases are challenging to manage in wild ungulate populations, particularly when there are many ways the disease can spread. Wildlife management agencies often need to take action to control disease spread, but it is unclear which actions are most effective in constraining disease because the importance of different spread mechanisms is not fully understood. This project will aid state wildlife...
A citizen science program for brown treesnake removal and native species recovery at a National Historical Park in Guam
The National Park Service (NPS), U.S. Geological Survey (USGS), U.S. Fish and Wildlife Service (USFWS), and community Citizen Scientists are working together to remove brown treesnakes at War in the Pacific National Historical Park - Asan Beach Unit to aid restoration of native avian and reptile species.
Future Aquatic Invaders of the Northeast U.S.: How Climate Change, Human Vectors, and Natural History Could Bring Southern and Western Species North
Researchers will evaluate the potential of aquatic species to invade the Northeast U.S. Following the identification of appropriate target species by regional stakeholders, researchers will gather data from the NAS database and develop models to determine habitat suitability for each species.
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.
Siren: The National Early Detection and Rapid Response Information System
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.
Predicting risk of annual grass invasion following fire in sagebrush steppe and rangeland ecosystems
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.
Predicting the phenology of invasive grasses under a changing climate to inform mapping and management
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...
Assessing invasive annual grass treatment efficacy across the sagebrush biome
We are using existing datasets that span broad spatial and temporal extents to model the efficacy of invasive annual grass treatments across the sagebrush biome and the influence of environmental factors on their success. The models we develop will be used to generate maps of predicted treatment efficacy across the biome, which will be integrated into the Land Treatment Exploration Tool for land...
