The Corredor Biológico Nevados de Chillán - Laguna del Laja Is located in Chile's Patagonia region, which is a global biodiversity hotspot. The biological corridor connects three core areas: Ñuble National Reserve, Laguna del Laja National Park and the Los Huemules de Niblinto National Reserve.
The Corredor Biológico Nevados de Chillán - Laguna del Laja Biosphere Reserve Is located in the northern part of the Patagonia region within the Central Chilean zone which is a global biodiversity hotspot, also characterized by an abundance of endemic species.
The biological corridor connects three core areas: Ñuble National Reserve, Laguna del Laja National Park and the Los Huemules de Niblinto National Reserve and Nature Sanctuary, with a total of 565,000 ha (1,396,000 acres).
The Nevados de Chillan and Rio Polcura sites are labeled high priority for the conservation of biodiversity in Chile due to their richness of wildlife (particularly insects) and flora, high genetic diversity and presence of huemules. Recent studies indicate that the fauna represented is approximately 155 species and flora at approximately 355 species.
Laguna del Laja National Park is a Chilean national park located in the Andean mountain foothills, within the VIII Region (Bío-Bío Region) of central Chile. The park features spectacular mountain landscapes, whose main attractions are the Antuco Volcano, Sierra Velluda and Laguna del Laja (Laja Lake). The latter gives the name to this protected area but it only borders the park.
The park ranges in elevation from 976 m (3,200 ft) to 3,585 m (11,760 ft) at Sierra Velluda. Although a little snow caps Antuco volcano, much more snow adorns the two major summits of its southern neighbor, even during Chile’s summer.
The park lies within the Valdivian temperate forests ecoregion. Endangered and rare vegetation species are found in the park. Among them are: ciprés de la cordillera, araucaria, maitén del Chubut and radal enano.
Sharp ridges and deep valleys carve this rugged region, which alternates between bare rock and lush vegetation. Another summit in the park, although least prominent, is Cerro Cóndor at 1,668 m (5,472 ft). Laguna del Laja National Park forms part of the Bío Bío River basin. Some small tributaries of Laja River originate in the park.
Laguna del Laja National Park is home to a wide variety of wildlife, including the cougar and foxes (particularly the chilla and the culpeo). At least 47 bird species have been identified in the park.
