From the notice

Invasive species are one of the greatest threats to biodiversity, biosecurity, ecosystem functioning, and human well-being in Hawaiʻi. Managers are increasingly concerned about the horticultural trade because it is the predominant pathway for non-native plant introduction in the state. However, they currently lack information about which species pose the greatest risk now and in the future. By analyzing invasion records and ornamental trade data for approximately 19,000 plant taxa, this project will identify horticultural species likely to establish in Hawaiʻi based on local conditions. In doing so, the project will identify geographic areas with the highest invasion risk and highlight species of concern, taking into account invasion history, weed risk scores, nursery locations, and their overlap with human infrastructure and conservation areas. Findings will inform risk-based screening, early detection priorities, and management planning for federal and state partners including the U.S. Fish and Wildlife Service, National Park Service, and Hawaiʻi Department of Land and Natural Resources Division of Forestry and Wildlife. By improving invasive species management, this project will support the mitigation of hazards like wildfires and erosion that can be exacerbated by invasive plants, improving state and local preparedness in line with the goals of EO 14239 -Achieving Efficiency Through State and Local Preparedness (March 19, 2025). This work also supports the goals of EO 143
