Feeding billions of people is no small task. Modern agriculture has grown and evolved to meet the demand, but it comes at a heavy cost. Soil degradation, erosion, loss of biodiversity—though agriculture is critical for sustaining us, these methods can devastate our natural ecosystems.
This modern problem requires a long-standing solution: to let nature heal itself. It starts with bison, a species uniquely capable of supporting its surrounding environment, and one that was also virtually eradicated through overhunting.
Bison reintroduction isn’t just about reviving a species once driven to the brink of extinction. It’s about breathing life back into the grasslands and restoring environmental sustainability.
Bison and Grassland Restoration
As a keystone species in the grasslands, bison play a critical role in maintaining the structure and health of their ecosystem.
Grasslands have been one of the most productive and indispensable areas for agriculture. But through excessive tillage, large-scale irrigation, monoculture farming, and more, these same agricultural practices have drained grasslands of their inherent resources.
By reintroducing bison into their natural habitat, this species can restore balance and counteract much of the damage done through large-scale agricultural practices, helping increase environmental stability.
And bison do it all through a few simple behaviors.
Grazing Restores Grassland Biodiversity
Unlike the uniform grazing habits of livestock confined to a limited area, bison graze selectively and roam constantly. Whereas livestock such as cattle can decimate large areas of grass due to this captivity, bison grazing patterns create patches of opportunity for different plant species to thrive.
The effect goes beyond foliage. Greater plant diversity supports a wider variety of insects, birds, and wildlife. Likewise, this overall increase in biodiversity means better nutrient cycling and pollination, rejuvenating the earth.
Roaming & Manure Improve Soil Health
Heavy plowing, synthetic fertilizers, and widespread use of pesticides gradually deplete soil health. And when 95% of the food we consume is grown in topsoil, soil health impacts more than just the environment; it ties into our own food security.
As bison roam, they break up the soil with their hooves, allowing air, water, and nutrients to penetrate deeper. Simultaneously, the weight of their steps presses seeds further into the ground, encouraging new growth. Their urine and manure also act as natural fertilizers, enriching the soil with nitrogen, phosphorus, and potassium.
Altogether, bison act as effortless gardeners just by wandering the prairie, leaving behind healthier ecosystems in their wake.
North American Bison Partners with Independent Bison Ranchers
The benefits of bison reintroduction are innumerable. At North American Bison, we recognize bison for what they are—a vital grassland species, and one deserving of honor and respect. We partner with independent ranchers dedicated to the natural and humane treatment of bison, helping bring sustainability to our food supply with bison free to roam, graze, and live as they’re meant to.
