Serranía El Peligro

Parque Natural Regional Serrania El Peligro is a 2,647-hectare (26.47 km²) protected area in the Ricaurte province of Boyaca department, Colombia, declared in 2009 and managed by the Corporacion Autonoma Regional de Boyaca (Corpoboyaca). ^[1] Set in the interior Andes of Boyaca across the municipalities of Moniquira and Arcabuco, the park rises through elevations of roughly 2,050 to 2,800 metres. It is notable for protecting Andean oak (Quercus humboldtii) forest and forms part of the Iguaque-Guantiva-La Rusia oak corridor, one of Colombia's most important remaining concentrations of Andean oak woodland. The park safeguards strategic watersheds that supply water to the towns of Moniquira, Arcabuco, and Gachantiva.

The oak forests of Serrania El Peligro support a varied Andean fauna characteristic of the Ricaurte highlands. Mammals likely to occur include small deer, paca, tayra, squirrels, and a range of bats and small carnivores typical of montane oak woodland. Birdlife is rich, with the oak forest providing habitat for tanagers, woodpeckers, toucanets, and various forest passerines, while the dense, humid canopy also shelters amphibians and reptiles adapted to cool, moist conditions. As a node in the Iguaque-Guantiva-La Rusia corridor, the park contributes to habitat connectivity that allows forest wildlife to move between protected areas across the interior Boyaca Andes. ^[1]

The defining feature of Serrania El Peligro is its well-preserved Andean oak forest dominated by Quercus humboldtii, the only true oak native to South America, which forms dense stands across much of the serrania. ^[1] These forests are layered with encenillo, gaque, and other montane trees, and their canopies and trunks support abundant mosses, ferns, orchids, and bromeliads in the humid mountain climate. Understorey vegetation includes Chusquea bamboo and a diversity of shrubs and herbs. This oak-dominated landscape is part of the regionally significant Iguaque-Guantiva-La Rusia oak corridor and is valued both for its biodiversity and for the role of the forest in protecting soils and regulating water.

Serrania El Peligro lies within the Eastern Cordillera of Colombia, here forming the interior ranges of the Ricaurte province in central Boyaca. The bedrock consists of folded and faulted sedimentary rocks—sandstones, mudstones, and limestones—deposited in ancient basins and uplifted during Andean orogeny. The serrania itself is a forested ridge system with steep slopes, ravines, and intervening valleys carved by long-term erosion. Soils developed over these sedimentary substrates, combined with the deep leaf litter of the oak forest, give the area good water-retention capacity, helping to sustain the streams that descend toward the surrounding municipalities.

The park experiences a cool, humid montane climate, with temperatures moderating between roughly 2,050 and 2,800 metres of elevation and frequent cloud cover and mist enveloping the oak forest. Rainfall follows the bimodal pattern typical of the interior Boyaca Andes, with wetter periods generally around April-May and October-November interspersed with drier spells. High humidity and persistent fog sustain the lush epiphyte communities of the oak canopy and feed the headwater streams within the reserve. These moist, temperate conditions are well suited to Andean oak forest and underpin the park's function as a local water source.

The Ricaurte province in which Serrania El Peligro lies was part of the ancestral Muisca territory of the Boyaca highlands and later became a centre of Spanish colonial settlement, with nearby Villa de Leyva and Moniquira developing as historic towns. The surrounding municipalities of Moniquira, Arcabuco, and Gachantiva are traditional agricultural communities known for crops such as sugarcane-derived panela, coffee, and fruit, as well as livestock. For generations these communities have drawn water from the forested serrania, and growing recognition of the link between the oak forests and reliable water supply contributed to local support for protecting the area.

Parque Natural Regional Serrania El Peligro was declared in December 2009 by Corpoboyaca through Acuerdo 0022, to conserve one of the better-preserved tracts of Andean oak forest in the interior Boyaca Andes. ^[1] The designation responded to the dual goals of protecting the regionally important oak woodland and securing the watersheds that supply nearby towns. By formally protecting roughly 2,647 hectares across the municipalities of Moniquira and Arcabuco, the park reinforced the Iguaque-Guantiva-La Rusia oak corridor and strengthened the network of regional reserves working to maintain forest cover and ecological connectivity in central Boyaca. ^[2]

The principal attraction of Serrania El Peligro is its dense, humid Andean oak forest, a relatively rare and atmospheric ecosystem offering opportunities for birdwatching, nature walks, and quiet immersion in mature montane woodland. The park's location in the Ricaurte province places it near popular destinations such as Villa de Leyva and the town of Moniquira, allowing it to be combined with a broader cultural and natural itinerary in central Boyaca. As a regional reserve focused on conservation, its trail infrastructure is modest, and visits are best arranged with local guides familiar with the serrania's terrain and access points around Moniquira and Arcabuco.

The nearest town to Serrania El Peligro is Moniquira, about ten kilometres away, with Arcabuco offering another point of access; the regional capital of Tunja lies roughly 80 kilometres distant. Roads to the reserve are mostly secondary routes, and reaching the forested ridges may require travel on foot or by sturdy vehicle along rural tracks. There are few formal tourist facilities within the park, so visitors generally base themselves in Moniquira or nearby towns for lodging and services and coordinate access with Corpoboyaca or local community organizations. ^[1] Its position near the well-travelled Villa de Leyva area makes the park accessible as part of a regional visit.

Conservation at Serrania El Peligro centres on safeguarding its Andean oak forest, a regionally significant ecosystem within the Iguaque-Guantiva-La Rusia oak corridor, and on protecting the watersheds that supply Moniquira, Arcabuco, and Gachantiva. Managed by Corpoboyaca, the park works to maintain high forest cover and ecological connectivity across the interior Boyaca Andes. Key threats include clearing of oak forest for agriculture and pasture, firewood and timber extraction, and pressure on water resources from surrounding communities. Management priorities include preventing further forest loss, restoring degraded areas, and engaging local farmers in sustainable land-use practices that reconcile rural livelihoods with the long-term protection of the oak woodland and its water-producing function. ^[1]
