Prescribed fire's uneven success against invasive shrubs reveals deeper ecosystem and management challenges

Scientific studies show that the effectiveness of prescribed fire depends on factors like fire intensity, frequency, and the physiological traits of the target species. Invasive shrubs like burning bush and privet have evolved mechanisms to resprout after fire, which must be understood in the context of their broader ecological strategies.
The challenge of managing invasive shrubs with prescribed fire is not just a technical issue but a systemic one, shaped by historical land degradation, the exclusion of Indigenous knowledge, and the limitations of single-intervention strategies.
By integrating Indigenous fire stewardship, adopting multi-pronged management approaches, and investing in long-term ecological restoration, we can move toward more resilient ecosystems. This requires not only scientific understanding but also a rethinking of power structures in land management and a commitment to cross-cultural collaboration. The lessons from Indigenous practices and global fire traditions offer a path forward that is both ecologically effective and culturally just.
