A definition
Prescribed grazing is the controlled, intentional use of livestock — most often goats, sheep, or cattle — to manage vegetation on a specific landscape for a defined ecological or operational outcome. Unlike traditional pasture-based ranching, the goal of prescribed grazing isn't primarily meat or fibre production. It's land stewardship: shaping plant communities, reducing wildfire fuels, recovering native habitat, or preparing sites for restoration.
How it works
A certified prescribed grazing practitioner develops a grazing plan tailored to each site. The plan specifies which species of livestock are best suited to the target vegetation, the stocking density, the timing of the grazing event relative to plant phenology, and the rotation schedule needed to achieve the intended outcome without overgrazing.
Animals are typically contained with temporary electric fencing and supervised by a herder. Daily monitoring tracks vegetation response, animal health, water access, and predator pressure. Outcomes are documented and benchmarked against the original prescription.
Environmental benefits
Invasive Species Control
Targeted livestock browsing suppresses thistle, knapweed, buckthorn and other invasives without herbicides.
Wildfire Fuel Reduction
Removing fine fuels in interface zones lowers ignition risk and slows fire spread.
Ecological Restoration
Selective grazing supports native plant recovery and habitat for pollinators and wildlife.
Soil & Carbon Health
Well-managed grazing cycles improve soil structure, water retention, and carbon sequestration.
Chemical-Free Stewardship
An alternative to herbicide and mechanical clearing in sensitive landscapes.
Safer Operations
Reduced machinery use in steep, rocky, or environmentally sensitive sites.
Where it's used in Canada
Canadian municipalities, conservation authorities, utility corridor managers, parks agencies, and private landowners are adopting prescribed grazing for wildfire mitigation in the wildland-urban interface, invasive species control in protected areas, vegetation management under transmission lines, and restoration of grasslands and wetlands.
The role of CPGA
The Canadian Prescribed Grazing Authority sets national standards, certifies practitioners, and maintains a public directory of recognized professionals — so landowners and procurement teams can confidently engage qualified providers.
