Cutervo

Cutervo National Park covers 8,214 hectares in the Department of Cajamarca in northern Peru, in the Andes mountains near the town of San Andrés de Cutervo. Established in September 1961 by Law 13694, Cutervo is Peru's first national park and one of the first national parks established in South America. The park protects a section of montane cloud forest and limestone cave systems in the Andean highlands of northern Peru at elevations between 2,000 and 3,000 meters. The park is particularly notable for its spectacular cave system — the Cueva de los Guácharos — which houses large colonies of oilbirds (guácharos). While relatively small, the park's historical significance as Peru's first protected area and its unique cave ecosystem give it outsized conservation importance.

The park's primary wildlife attraction is its large colony of oilbirds (Steatornis caripensis) — locally called guácharos — that roost and nest in the park's cave systems. These nocturnal, fruit-eating birds are unique among birds in using echolocation for cave navigation. The cloud forest supports spectacled bears, the only bear species native to South America, which feed on bromeliads and cloud forest fruits. Pumas and ocelots are present. The Andean tapir may occur at lower elevations. Woolly monkeys inhabit the forest canopy. Andean cock-of-the-rock — one of Peru's most spectacular birds — displays in leks in the cloud forest. Torrent ducks inhabit mountain streams. Dozens of hummingbird species pollinate the cloud forest flowers.

The park's cloud forest ecosystem is characterized by persistent fog and high moisture, creating ideal conditions for extraordinary plant diversity. Trees draped in mosses, lichens, and epiphytes dominate the forest canopy, with species including Clusia, Weinmannia, and Podocarpus. Bromeliads and orchids festoon every available surface, including thousands of orchid species in the broader northern Peruvian cloud forest region. Tree ferns create an ancient-looking understory. The forest floor is deep with decomposing leaves and hosts specialized understory plants adapted to low-light conditions. The limestone substrate in cave-margin areas supports unique geophyte communities.

The park's most significant geological feature is its limestone karst system — the Cueva de los Guácharos and associated cave networks. The limestone was deposited as marine sediments in the Mesozoic era and later uplifted and folded by Andean tectonics. Chemical weathering of the soluble limestone by rainwater and organic acids has produced caves, sinkholes, springs, and collapse features typical of karst topography. The cave interiors contain stalactites, stalagmites, and other speleothems formed by calcium carbonate precipitation. The surrounding mountains are composed of a mix of sedimentary and volcanic rocks of Andean age. The cloud forest terrain is steep and deeply dissected by rivers cutting into the limestone.

Cutervo's cloud forest climate is cool, misty, and humid year-round. Annual rainfall ranges from 1,500 to 2,500 mm, concentrated in the wet season from October through April. Dry season (May–September) sees reduced but still significant rainfall. Temperatures at the park's elevation (2,000–3,000 m) average 12–18°C, with nighttime temperatures occasionally approaching freezing. Cloud and mist are nearly constant, creating the perpetual moisture that sustains the cloud forest. Conditions for visiting are generally best from May to September when rainfall is lower and visibility is better. The cave interior maintains a constant temperature year-round regardless of external conditions.

The Cajamarca region was one of the most important areas of pre-Inca and Inca civilization in Peru. The Cajamarca people developed a sophisticated culture before Inca incorporation in the fifteenth century. Cajamarca city, near the park, was the site of the famous 1532 capture of Inca emperor Atahualpa by Spanish conquistador Francisco Pizarro — a pivotal moment in the Spanish conquest of the Americas. The park area was settled by Spanish-descended Andean communities engaged in cattle ranching and subsistence agriculture. The guácharo caves were known to local communities for generations before scientific investigation. The town of San Andrés de Cutervo, which gives the park its name, serves as the gateway community.

Cutervo was established as Peru's first national park by Law 13694 on September 8, 1961, under President Manuel Prado Ugarteche. The park's creation was motivated primarily by the need to protect the remarkable oilbird colony in the Cueva de los Guácharos. The park was proposed and championed by Dr. Hernando de Macedo Ruiz, a Peruvian naturalist who recognized its biological significance. Despite its historical importance as Peru's first park, Cutervo has received relatively limited funding and visitor infrastructure compared to larger Peruvian parks. In 1979, the park boundaries were modified. SERNANP currently manages the park with a small ranger team. Scientific studies of the oilbird colony and cloud forest biodiversity have been ongoing since the park's founding.

The Cueva de los Guácharos is the park's central attraction — a spectacular limestone cave housing thousands of oilbirds that fill the cave with their distinctive raucous calls. Visits to the cave require a local guide and can be arranged in San Andrés de Cutervo. The cloud forest trails around the cave provide excellent opportunities for birdwatching, including Andean cock-of-the-rock, spectacled bear sign observation, and diverse hummingbird species. The forest itself, draped in mosses, bromeliads, and orchids, is extraordinarily atmospheric. The Andean landscape surrounding the park offers additional hiking opportunities.

The park is accessed from the city of Cajamarca (170 km), which has an airport with Lima connections, or from Chota (approximately 90 km). The town of San Andrés de Cutervo (adjacent to the park) has basic accommodation. SERNANP requires visitor registration. Local guides for cave visits are mandatory and available through the park administration. The road from Chota to San Andrés de Cutervo is partly unpaved and can be difficult after heavy rain. The nearest city with comprehensive services is Cajamarca. The best visiting time is May through September during the drier months.

Cutervo faces significant conservation challenges from its small size and surrounding land use pressure. Agricultural encroachment, cattle grazing, and deforestation in the park's buffer zone fragment the cloud forest habitat. The park's small area limits its effectiveness as a refuge for wide-ranging species like spectacled bears and tapirs. Illegal hunting and collection of forest products occur. The oilbird colony, while the park's founding reason for protection, can be disturbed by insensitive cave visits. SERNANP has limited personnel and budget for management of this remote park. Conservation NGOs have proposed expanding the park and creating wildlife corridors connecting it to larger forest blocks in the broader Cajamarca region.
