Effects of Invasive Alien Plants on Fire Regimes

Effects of Invasive Alien Plants on Fire Regimes


This article considers how  invasive plant species affect native ecosystems by altering fuel properties, fire behavior and fire regime characteristics. These may impact the ability of a site to restore to its previous state.

Conclusions & Takeaways

If regime changes promote the dominance of an invasive plant, then an invasive fire regime cycle can be established. As more ecosystem components and interactions are altered, restoration of preinvasion conditions becomes more difficult. The authors provide a model describing the relationships between invasive plants and fire regimes.
