Considerable experimental and theoretical work has been done on general concepts regarding nonnative species and disturbance, but experimental research on the effects of fire on nonnative invasive species is sparse. We begin this chapter by connecting fundamental concepts from the literature of invasion ecology to fire. Then we examine fire behavior characteristics, immediate fire effects, and fire regime attributes in relation to invasion potential. These concepts form the basis for examining the literature that supports or refutes several common generalizations regarding fire effects on nonnative invasives. We conclude with a summary of management implications regarding fire effects on nonnative invasive plants.
