In 2004, Kris Tompkins played a pivotal role in securing a Chilean ranch aimed at ecological restoration. This significant initiative targeted the revival of native ecosystems, minimizing livestock grazing impacts, and dismantling barriers that hinder wildlife. By 2018, the successful culmination of these efforts led to the formation of Patagonia National Park, enhancing the conservation footprint to cover 15 million acres combined across Chile and Argentina.

Billionaire real-estate developer Donald Bren transformed a significant part of the historic Irvine Ranch into protected public lands. After becoming chairman of the Irvine Company, he spearheaded major conservation milestones over the years. The Irvine Ranch now has over 57,000 acres preserved, providing habitats for diverse wildlife. In 2005, the Irvine Ranch Conservancy was established to ensure the ongoing care of these protected areas.
