The Bitterroot Valley, located in western Montana, occupies a critical hydrological and ideological position within the Cascadian bioregion. Far from peripheral, the Bitterroot watershed is connected to Cascadia by definition, contributing directly to the Columbia River system. Through this ecological linkage—and with a vision grounded in bioregional sovereignty—the Bitterroot stands poised not as an outlier, but as a potential exemplar of what the Cascadia project seeks to realize: locally governed, economically autonomous regions defined by culture and ecology, not political boundaries.
Cascadia Defined: Watershed as Territory
Cascadia is a bioregional concept rooted in the premise that natural systems—specifically watersheds—form the most coherent basis for governance, economy, and cultural identity. Both David McCloskey’s and Bates McKee’s formulary definitions of Cascadia affirm this approach:
McCloskey’s View: Cascadia is the land, peoples, and lifeways of the Columbia and Fraser watersheds.
McKee’s Model: Centers on geological integrity across the Columbia basin.
By these standards, the Bitterroot River—flowing into the Clark Fork and eventually the Columbia—is part of the Pacific drainage basin. The valley is not adjacent to Cascadia; it is inherently within it.
Ecological Membership: The Bitterroot in the Bioregion
The Bitterroot watershed contains ecological traits characteristic of Cascadia, despite its distance from the eponymous mountain range:
Hydrological Integration: As a tributary of the Columbia River, the Bitterroot’s waters contribute to the very artery that geographically, ecologically, and culturally binds the Cascadian biome.
Ecoregional Continuity: Forest communities, wildlife corridors, and topographic features are consistent across the bioregion—from the Selway-Bitterroot Wilderness to the Cascade foothills.
From this standpoint, the Bitterroot Valley is geophysically Cascadian. While many overlook Cascadia’s connection to its mountainous interior, these headwaters are critical to its bioregional coherence.
Autonomy as Aspirational Identity
While elements of ecological stewardship and localism already do exist in the Bitterroot, systemic autonomy—economic, political, and cultural—remains aspirational. Cascadia offers a model for how this transformation might unfold:
Economic Autarky: Transitioning from dependence on global supply chains toward regenerative local economies—centered on agriculture, decentralized energy, and cooperative production.
Political Self-Governance: Empowering communities to make decisions based on place-based needs, potentially through watershed councils, regional assemblies, or participatory governance networks.
Cultural Pluralism & Sovereignty: Valuing indigenous leadership, settler heritage, and environmental ethics—protecting identity without relying on nationalist constructs.
By embracing Cascadian principles, the Bitterroot could evolve from passive inclusion to active leadership within the bioregion.
Reimagining Regional Identity
Incorporating the Bitterroot into the broader Cascadian movement is not a matter of redrawing ideological boundaries—it’s a call to realize the region’s latent potential:
From Abstraction to Agency: Cascadia reframes the Bitterroot from being "Montana’s west" to being "Cascadia’s east."
From Extraction to Regeneration: Economic development rooted in ecological constraints, not market expansion.
From Representation to Participation: Political systems arising organically from the land and community, not imposed externally.
Watershed as Mandate
The Bitterroot Valley is not tangential to Cascadia—it is central, by virtue of hydrology, ecology, and shared destiny. Recognizing this inclusion reorients regional dialogue from reactive to visionary. Within the framework of Cascadia, the Bitterroot can explore a future where governance aligns with land, economies sustain people without exploitation, and identities reflect lived relationships with place.
