In 1900, the southern white rhinoceros was the most endangered of the five rhinoceros species. Less than 20 rhinos remained in a single reserve in South Africa. By 2010, white rhino numbers had climbed to more than 20,000, making it the most common rhino species on the planet.

Founded 30 years ago in Bozeman, Montana, PERC—the Property and Environment Research Center—is the nation’s oldest and largest institute dedicated to improving environmental quality through property rights and markets.
PERC’s publications, each designed to resonate with specific groups, move ideas generated at PERC to broader audiences.
Research is at the heart of PERC's work, with a focus on the question: What is the link between economic growth and environmental quality?
The goal of PERC’s programs is to fully realize the vision of establishing “PERC University,” where scholars, students, policy makers, and others convene to expand the applications of free market environmentalism.
PERC's fellowships share a common goal of exposing new scholars, students, journalists, and policy makers to free market environmentalism, as well as enable scholars already familiar with FME to explore new applications.
PERC continues to publish and present a broad range of research and discussion through podcasts, videos, and other multimedia channels.
