Colonial land mismanagement and climate change amplify invasive grass expansion in BC’s post-fire landscapes, risking prolonged wildfire cycles

The current crisis is rooted in 150 years of colonial land policies that displaced Indigenous fire practices and prioritized industrial extraction over ecological resilience. Fire suppression policies, introduced in the early 20th century, disrupted natural fire cycles, allowing fuel buildup. Industrial logging in BC’s interior has further destabilized soils, making them vulnerable to invasive grass species like cheatgrass. Historical parallels include the Dust Bowl of the 1930s, where monoculture agriculture and overgrazing led to catastrophic soil erosion and windstorms.
The invasive grass crisis in BC’s post-fire landscapes is not an ecological anomaly but a symptom of colonial land mismanagement, industrial extraction, and climate change.
For over a century, Western fire suppression policies and logging practices have disrupted natural fire cycles, creating conditions where invasive grasses thrive. Indigenous fire stewardship, which maintained fire-resistant landscapes for millennia, offers a tested solution but remains sidelined by institutional inertia and legal barriers. The UBC study’s focus on short-term recovery obscures the deeper need for systemic change: land-back agreements, ecologically restorative forestry, and climate-adaptive governance. Without centering Indigenous leadership and dismantling extractive industries, BC risks locking in a cycle of megafires and grass-dominated landscapes. The path forward requires not just technical fixes but a reimagining of humanity’s relationship with fire and land, where stewardship replaces domination. This crisis is a call to action for policymakers, scientists, and communities to collaborate across knowledge systems and prioritize long-term ecological and cultural resilience over short-term economic gains.
