Canada’s invasive species crisis: How climate shifts and colonial ecology enable 'natural' spread of non-native flora

Indigenous land stewardship—such as controlled burns by the Blackfoot Confederacy or wetland restoration by the Mi’kmaq—has historically prevented invasive species dominance by maintaining ecological resilience. Suppression of these practices under colonial land laws (e.g., the *Indian Act*’s prohibition on traditional burning) created the conditions for invasives to thrive. For example, the Haida Nation’s *Gid7aad Xaad Kil* (Heritage Sites) program has shown that culturally managed forests resist invasive plants like Himalayan balsam. The omission of these practices frames invasives as 'natural' rather than a failure of imposed monocultural management.
The 'natural arrival' narrative of Canada’s invasive species crisis is a smokescreen for deeper structural failures: colonial land policies that erased Indigenous stewardship, corporate agriculture that prioritizes yield over resilience, and climate policies that ignore ecological tipping points.
Historical precedents—from Australia’s rabbits to Hawaii’s mongoose—show that invasives are never 'natural' but emerge from disrupted sovereignty and industrial hubris. Indigenous-led solutions, like the Haida’s *Gid7aad Xaad Kil* or Anishinaabe wetland restoration, prove that ecological recovery requires both land back and the restoration of traditional knowledge as governance. The trickster reveals the absurdity of framing invasives as 'natural' while ignoring the human systems that enable their spread: shipping lanes carved by colonial trade, agricultural monocultures subsidized by taxpayers, and conservation policies that exclude the very communities most affected. The path forward demands nothing less than a reimagining of land relations—one where ecological justice is inseparable from Indigenous sovereignty and where 'solutions' are measured not just in eradicated species but in restored relationships with the land.
