responsibly sourced

Sheep ranching is the most prevalent land use in the Patagonia region but overgrazing is turning its grasslands into desert. To reverse the degradation, Patagonia has partnered with The Nature Conservancy and Ovis XXI to introduce a new sustainable grazing protocol.

The protocol employs holistic management practices that emphasize high-density grazing followed by adequate recovery time. Instead of simply slowing desertification, we are working toward the actual regeneration of Patagonia’s grasslands.
