Altos de Lircay National Reserve, Nature reserve in Talca Province, Chile.

Altos de Lircay National Reserve is a protected area in Talca Province that covers pre-Andean mountain terrain with three major rivers and changing vegetation zones at different elevations. The landscape includes volcanic peaks and shifts from forests to open grasslands as you move up the slopes.

The reserve was established in 1996 to protect the mountain forests and habitats of this region. It received protection status as an IUCN category IV area, which means active management focuses on preserving species and their environment.

The reserve lies in the huasa and typical zone of San Clemente, the commune it belongs to within Talca Province. Access runs through this area by paved road, and the reserve's rivers, the Lircay and the Claro, supply irrigation water to San Clemente. A digital film, "Maule Nativo. Provincia de Talca", financed by the Municipality of Talca and sponsored by the Club del Árbol de Talca, CODEFF and CONAFF, shows the reserve's plant species.

Access is via a paved road from Talca through San Clemente, about 66 km; snow can block the last 4 km in winter. A permanently closed gate requires collecting keys at the Centro de Información Ambiental, and visitors must register with the park rangers. Campers must use a gas stove, as fires are banned everywhere.

The reserve protects a stand of roble Maulino and ciprés de la cordillera, both threatened, alongside the tricahue parrot and Molina's hog-nosed skunk. Seven of Chile's ten Nothofagus species grow here, including the Vulnerable hualo (Nothofagus glauca) and huala (Nothofagus leonii). A digital film, "Maule Nativo. Provincia de Talca", financed by the Municipality of Talca and sponsored by the Club del Árbol de Talca, CODEFF and CONAFF, shows these species.
