Wildland fire is a process integral to the functioning of most wildland ecosystems of the United States. Where nonnative plant species have invaded wildlands or have potential to invade, fire may influence their abundance and the effects of the nonnative species on native plant communities. This volume synthesizes scientific information regarding wildland fire and nonnative invasive plant species, identifies the nonnative invasive species currently of greatest concern in major bioregions of the United States, and describes emerging fire-invasive issues in each bioregion and throughout the nation. This report can assist fire managers and those concerned with prevention, detection, and eradication or control of nonnative invasive plants. It can help increase understanding of plant invasions and fire and can be used in planning fire management and ecosystem-based land management activities.
