Description

Invasive plants vary in their sensitivity to fire during the invasion process. Some species are sensitive to fire management at all stages. Both seeds and non-sprouting adult plants experience high mortality after fire such that the species is unable to reproduce, spread, and become dominant in fire-frequented environments. In other cases, invasive species are resilient to occasional fire. Fire can stimulate germination in these species and promote spread, but fires that occur too frequently or before plants begin to reproduce can kill adult plants, deplete the seed bank, and prevent dominance at a site. Some species are unaffected or even promoted by fire. These species are often the most difficult to control, because they tend to survive fire by resprouting followed by rapid growth and sometimes abundant seed production that allows them to quickly gain dominance. Fire-plant relationships can change over time and are influenced by the environmental context, including the native community assemblage, soil fertility and hydrology, and presence of pests and pathogens.
