Invasive plants harm ecosystems by outcompeting native plants and destabilizing natural communities. To reduce harm, practitioners use control methods such as herbicides or mowing. Rising temperatures can create a fertilization effect that boosts plant growth, an impact that is even stronger in invasive species, which tend to grow much faster than non-invasive plants. As a result, the recommended doses and number of treatments of herbicides may no longer be effective for controlling invasive plants. To address the need for information on how invasive plant treatment strategies can be adapted to remain effective under warming temperatures in the Northeast, researchers will synthesize 1) practitioner knowledge on the success of past treatments and 2) the best available science on treatments. Incorporating science on whether and how treatment approaches can be more effective will address a critical need for invasive species practitioners in the Northeast, who report spending most of their time treating existing invasive plants.
This work aligns with the goals of EO 14239 -Achieving Efficiency Through State and Local Preparedness (March 19, 2025) by helping state and local practitioners mitigate invasive species-associated hazards, as well as 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 strengthening American leadership in adaptation science.
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.
