Woodland Wayquecha Biological Station -Amazon Peru

Woodland Wayquecha Biological Station – Amazon, Peru

The Woodland Wayquecha Biological Station Amazon Peru , located in the Amazon region of Peru, is situated in unique vegetation complexes found in areas characterized by the persistent or frequent presence of moving clouds or fog. These forests “extract” or capture moisture from the atmosphere, which is added to the normal precipitation, a phenomenon known as “horizontal rain” or “hidden rain.” Without the presence of trees, shrubs, and epiphytes, much of this moisture would remain in the atmosphere.

Compared to lowland rainforests, cloud forests like those in the Wayquecha area feature smaller trees, greater stem density, and twisted or tortuous trunks with leathery leaves. These forests are also home to a high number of epiphytic plants such as orchids, bromeliads, mosses, ferns, and lichens. In contrast to the lowland forests, cloud forests have fewer woody lianas. The soils are generally humid and have a thick layer of organic matter.

The diversity of trees, herbs, shrubs, and epiphytes in cloud forests is high, considering their relatively small surface area compared to tropical rainforests.

The level of endemism (species restricted to a specific area) in the flora and fauna is also high.

Cloud forests play a crucial role in providing drinking water and hydroelectric power to millions of people. On average, these forests absorb 1,000 millimeters of rainfall annually, acting like giant natural sponges. However, if a small area of these delicate forests is cleared, the rain and humidity, which were previously captured, can lead to soil erosion and unpredictable landslides.

Woodland cloud forests are patchily distributed across tropical regions and occupy less than 0.26% of the Earth’s surface. In Cusco, cloud forests (also called yungas) cover almost 27% of the region (19,260 km²), encompassing five provinces and eighteen districts.

The Wayqecha Biological Station

Wayqecha is located in the Cusco region, within the Paucartambo province and Kosñipata district. It borders the Manu National Park and sits at an elevation between 2,300 and 3,400 meters above sea level.

Access to Wayqecha is possible via the Cusco-Paucartambo-Acjanaco–Wayqecha route. The journey is approximately 140 km, taking between four and six hours, with most of the road being paved.

The station’s location offers easy access to two contrasting ecosystems: the humid, diverse, and ecologically fragile cloud forest (yungas), and the cold, exposed high Andean puna (mountain grasslands).

Wayqecha spans almost 600 hectares and is primarily dedicated to conservation, research, and environmental education. It has accommodations for researchers, including three double cabins with bathrooms and a camping area with showers, supporting around thirty researchers at a time. The station also features a dining room, multipurpose room, fully equipped kitchen, food storage, and staff rooms.

An artificial lagoon is used for wastewater treatment, minimizing environmental impact.

Additionally, Wayqecha has twelve marked trails for field studies, offering access to a variety of habitats. The station also boasts an innovative system of canopy walkways (Manuq Phullu Chaka), providing researchers with a unique perspective on the forest’s upper canopy.

These canopy walkways are invaluable for studying the ecology of Andean cloud forests. The majority of photosynthesis in these forests takes place at the treetops, making it a vital area for carbon capture, reducing the greenhouse effect, and supporting the entire food chain.

Wayqecha has been operational since September 2006 and offers a perfect environment for research. Since 2007, the Association for the Conservation of the Amazon Basin (ACCA) has provided scholarships for students and professionals from Peru and abroad to conduct research on the cloud forest ecosystem.

Since its establishment, Wayqecha has supported over sixty research projects. These studies have resulted in many published findings, with ongoing research continuing to explore the cloud forest’s rich biodiversity.

From 2007 to 2010, ACCA awarded forty-six scholarships to researchers, many of whom studied various aspects of the station’s unique ecosystem. Some examples of the research conducted include studies on the diversity of insects and pollinators in the Woodland Wayqecha Biological Station.

Insect Diversity in the Woodland Wayqecha Biological Station

Insects represent a vast and diverse group of arthropods, making up more than 90% of life forms on Earth. In the Amazon region, including the cloud forests of Wayqecha, there is still much to discover about the insect species present.

For example, one study focused on the diversity of ants at the Wayqecha Biological Station, examining species from the genus Pheidolus, with some species potentially new to science. The study found eighteen ant species, contributing valuable information to the understanding of ant biodiversity in the high Andean cloud forest.

Another study investigated the diversity of parasitoid wasps (family Ichneumonidae) along an altitudinal gradient from 800 meters to 3,400 meters above sea level. A total of 141 species were identified, with species diversity peaking at mid-elevations.

Additionally, a study on bee diversity found 63 morphospecies across five families, highlighting the importance of

these insects in pollination and the ecological balance of the region.

Woodland Wayquecha Biological Station -Amazon Peru-   Orchid Pollination in Manu National Park

Cloud forests, particularly in the Manu National Park, are home to some of the highest orchid diversity in the world.

Orchids in this region are pollinated by various insects, including butterflies, beetles, flies, and bees. The

interaction between orchids and their pollinators is vital for the reproduction of these plants.

Research conducted in Wayqecha examined the insects that pollinate orchids, revealing a diversity of pollinators,

primarily tachinid flies. These flies are important for the pollination of orchids that mimic the appearance of

female flies. However, despite the large number of orchids in the area (over 250 species), the pollinating insect

population is surprisingly low, likely due to the seasonal nature of orchid blooming.

Conclusion

The Woodland Wayqecha Biological Station is an invaluable site for research and conservation of the Amazon

cloud forest. Its unique biodiversity, high levels of endemism, and role in carbon sequestration make it an essential

area for ecological studies. Efforts to preserve this fragile ecosystem are crucial for maintaining global environmental balance

and protecting the species that depend on it.
