Caribou Migration and Industrial Development

Caribou require intact migration corridors spanning thousands of kilometers, making industrial development one of the greatest threats to population welfare and survival.

Key Facts

Barren-ground caribou migrate up to 5,000 kilometers annually between calving grounds and winter range
Seismic lines, pipelines, and roads create linear disturbances that caribou avoid, fragmenting habitat
Woodland caribou in boreal forests show significant displacement from cutblocks and roads up to 5 kilometers away
Calving ground disturbance during late May through July causes calves to be separated from mothers, increasing mortality
The Porcupine caribou herd of 197,000 animals uses Alaska and Canada, requiring binational conservation coordination

Welfare Considerations

Caribou welfare during migration includes the physical demands of long-distance movement and the critical nutritional recovery on calving grounds. Industrial disturbance that disrupts migration routes or calving grounds causes females to abandon calves, increases energy expenditure on avoidance, and reduces access to optimal forage. Individual calves separated from mothers face starvation and predation. The cumulative effect of industrial development on caribou welfare operates at landscape scale - no single project tells the full story of habitat fragmentation effects.

What You Can Do

Support Indigenous-led land protection efforts in caribou migration corridors
Advocate for environmental impact assessment requirements addressing cumulative industrial development
Choose wood products certified to standards protecting boreal forest from clear-cutting in caribou habitat
Support binational conservation agreements protecting caribou herds that cross international boundaries
Learn about caribou ecology and the scale of migration when engaging with pipeline and development policy
