Cooperative Agreement for affiliated Partner with the Great Plains Cooperative Ecosystem Studies Unit

This Notice of Funding Opportunity (NOFO) is for a U.S. Geological Survey (USGS) National and Regional Climate Adaptation Science Center (NRCASC) competitive research award to a CESU partner. Projects supported under this cooperative agreement should advance Administration priorities, including, but not limited to, American energy dominance, critical mineral development, water security,

infrastructure resilience, and natural hazard preparedness. Research and activities may incorporate scientific expertise in areas such as hydrology, geology, geospatial science, biosecurity, and near-earth space science, including extreme events such as drought, flooding, wildland fire, coastal erosion, severe storms, and geologic hazards, to develop actionable science, data, and tools

that support informed decision-making by resource managers and stakeholders. Invasive plants harm ecosystems and economies by reducing native biodiversity and altering native communities. However, scientists still do not fully understand why invasive species cause severe impacts in some places but not others.

This project examines how drought, temperature, rainfall, wildfire, and land management practices (such as hay harvesting) influence the spread and ecological impacts of two invasive species in Oklahoma –the invasive grass King Ranch bluestem and eastern red cedar. The research will leverage existing long-term field experiments, regional plant distribution data, and environmental

scenarios to predict where these invasive species may become most problematic under future conditions. King Ranch bluestem and dense stands of eastern red cedar have been linked to the rapid spread of wildfires. This work supports the goals of EO 14239 - Achieving Efficiency Through State and Local Preparedness (March 19, 2025); EO 14308 -Empowering Commonsense Wildfire Prevention and

Response (June 12, 2025) by improving invasive species hazard mitigation for state and local practitioners, as the work addresses the elevated fire risk posed by these invasive species. This work also supports EO 14313 -Establishing the President's Make America Beautiful Again Commission (July 3, 2025 ) by advancing science-informed conservation of natural resources and strengthening the

capacity of agencies and communities to safeguard vulnerable ecosystems from biological degradation, in addition to EO 14303 -Restoring Gold Standard Science (May 23, 2025) and SO 3441-Implementing the Requirements of Executive Order 14303, Restoring Gold Standard Science (August 29, 2025 ) by contributing to American leadership in adaptation science.
