EAT BEEF
CONSERVE PRAIRIE
Grass-fed.
Grass-finished.
Prairie-friendly.
Our cattle graze native grasses and prairie plants on hills that used to sit at the bottom of an ancient sea. This geology is the foundation for the Flint Hills—the world’s last remaining intact tallgrass prairie landscape, which our family (and cattle) help conserve.

Grass-Fed Beef Bundles
Our prairie-friendly beef comes from grass-fed and grass-finished cattle raised on regeneratively managed native prairie ranchland in the Flint Hills of Kansas without added hormones or antibiotics. These cattle live the “good life” in prairie, eating a diverse and nutritious diet of native grasses and forbs, contributing to the conservation and restoration of endangered tallgrass prairie.
Let’s build a food system that helps conserve, restore, and rewild our vanishing prairie by consciously consuming meat from animals raised on native grasslands in a way that bolsters biodiversity, provides critical wildlife habitat, and supports local families and communities.
