Chimborazo Fauna Production Reserve, Nature reserve in Chimborazo Province, Ecuador.

Chimborazo Fauna Production Reserve is a protected area stretching across three provinces and centered on Chimborazo mountain. The reserve includes high mountain grasslands and different ecological zones that shift with elevation.

The reserve was created on 26 October 1987 by Interministerial Agreement No. 437 and publicised in Official Registry No. 806 of 9 November 1987. In 1988 vicuñas were reintroduced from Peru and Chile, and the protected area is now home to a notable population of the species.

The reserve's name comes from the Chimborazo volcano, whose Quechua name Chimpurasu refers to a sacred mountain. Vicuñas, llamas and alpacas graze the páramo, and their cushioned feet help keep the original vegetation and water sources intact. About 80% of the reserve belongs to 38 peasant organizations, communes and cooperatives.

Access is via three first-order roads: the Panamericana Norte east of the reserve, the Ambato–Guaranda highway near the western limit, and the road from Riobamba to San Juan. The reserve lies 180 km south of Quito. Trails lead to the Hieleros route, the Abraspungo and Carihuairazo valleys, and La Chorrera–Templo Machay–Cuartel Inca–Yanarumi.

The mountain here extends farther into space when measured from Earth's center than the world's highest peak. This happens because of Earth's bulging shape at the equator, making it a surprising geographic fact.
