Biological Station Manu Park
Biological Station Manu Park: A Journey Through One of the Most Biodiverse Places on Earth
Manu National Park is one of the most extraordinary protected areas in Peru and a true paradise for nature lovers, wildlife enthusiasts, and adventurous travelers. As one of the thirteen national parks in Peru, Manu stands out for its immense size, exceptional biodiversity, and cultural significance.
Located in the regions of Cusco and Madre de Dios, Manu National Park stretches across an astonishing range of ecosystems, descending from the Andean highlands at 4,000 meters above sea level to the Amazon rainforest floodplains at just 300 meters. This dramatic elevation gradient creates a mosaic of habitats unlike anywhere else in the world.
A Vast Protected Area With a Unique History
Manu National Park was officially established on May 29, 1973, originally covering 1,532,806 hectares of pristine wilderness. In 2002, the park expanded when the lower Manu Valley—formerly classified as a Reserved Zone—was fully incorporated. Today, the park protects an impressive 1,692,137 hectares of untouched nature.
What makes Manu truly unique within Peru’s National System of Protected Natural Areas (SINANPE) is that it is the only national park in the country that safeguards an entire watershed. From glacial streams in the Andes to the winding rivers of the Amazon Basin, the Manu River system remains largely undisturbed. tambopata macaw clay lick
An Unmatched Diversity of Landscapes and Wildlife –
Manu National Park preserves a complete sample of Andean–Amazonian ecosystems in southeastern Peru. Cloud forests, high-altitude grasslands, lowland rainforest, and riverine habitats all coexist within the park’s boundaries.
Thanks to this ecological variety, Manu is considered one of the most biodiverse places on the planet. Scientists have recorded:
- Over 1,000 species of birds, including macaws, harpy eagles, and Andean cock-of-the-rock
- Hundreds of mammal species, such as jaguars, giant otters, tapirs, and several monkey species
- Thousands of plant species, many of which are still being studied
- A remarkable diversity of reptiles, amphibians, insects, and fish
For travelers interested in wildlife observation, photography, and conservation tourism, Manu National Park offers a once-in-a-lifetime experience.
Indigenous Cultures and Living Heritage -Biological Station Manu Park:
Beyond its natural wonders, Manu National Park is also a place of deep cultural importance. The park is home to the Matsigenka people, who maintain traditional lifestyles closely connected to the forest. Manu Rainforest Peru
In addition, Manu protects territories of other Indigenous groups, such as the Mashco-Piro (also known as Nomole), who live in voluntary isolation. Their presence reinforces the park’s global importance, not only as a biodiversity hotspot but also as a refuge for ancestral cultures and human diversity.
International Recognition by UNESCO
Manu’s global value has been recognized by UNESCO on multiple occasions:
In 1977, Manu National Park and surrounding areas were designated a Biosphere Reserve, covering 1,881,200 hectares
In 1987, UNESCO further honored the park by naming it a World Heritage Site, acknowledging its outstanding natural value and exceptional ecological integrity
These designations place Manu among the most important protected areas on Earth.

ITINERARY
Cocha Cashu Biological Station: Research Priorities for the Next Decade
The Cocha Cashu Biological Station (CCBS), located within the heart of Manu National Park, is one of the most important long-term ecological research sites in the Amazon Basin. This document outlines the research priorities that CCBS seeks to actively promote over the next ten years, providing a strategic framework to guide fundraising, academic partnerships, training programs, and support for emerging scientists.
By focusing on carefully selected research themes, CCBS aims to address some of the most urgent conservation challenges facing Manu National Park and Amazonian ecosystems more broadly. These priorities will shape collaborative efforts with universities, professors, conservation organizations, and government agencies, while continuing to welcome innovative research beyond these focal areas.
Strategic Research Lines at Cocha Cashu
After extensive evaluation, eleven core lines of research were identified as priorities for the coming decade:
1. Monitoring for Conservation
Developing and strengthening long-term ecological monitoring to inform adaptive management and conservation decision-making.
2. Implementation of the Manu National Park Monitoring Plan
Supporting and improving the official monitoring framework of Manu National Park to ensure effective protection of biodiversity.
3. Interdisciplinary and Intercultural Research (Including Art)
Promoting collaborations that integrate natural sciences, social sciences, Indigenous knowledge, and creative disciplines to deepen understanding of Amazonian systems.
4. Landscape Ecology and Environmental Change
Using landscape-level approaches to detect ecological change and provide essential environmental context for species-focused research.
5. Ecological Resilience and Restoration
Positioning CCBS as a control site for understanding ecosystem resilience and guiding restoration efforts in disturbed Amazonian landscapes.
6. Priority Species for Research
Focusing on species of high conservation and monitoring importance, including apex predators and indicator species.
7. Keystone Species and Ecological Interactions
Investigating species that exert a disproportionate influence on ecosystem structure and processes.
8. Terrestrial–Aquatic Ecosystem Interactions
Exploring the strong ecological connections between forests, rivers, wetlands, and floodplains.
9. Seasonality, Productivity, and Phenology
Understanding how seasonal cycles influence productivity, resource availability, and species behavior in lowland Amazonian ecosystems.
10. Local Impacts of Global Climate Change
Documenting climate-driven changes in hydrology, species distributions, and ecosystem function.
11. Other Emerging Research Areas
Maintaining flexibility to support novel research questions as new conservation challenges arise.
For each of these research lines, specific topics have been identified to clarify desired outcomes. In the future, specialized working groups will further refine research questions and hypotheses to maximize scientific impact.
This presents a major opportunity:
- To address fundamental, unanswered questions in tropical aquatic ecology
- To study evolutionary and ecological processes that closely resemble pre-human conditions
- To generate baseline data critical for understanding human impacts elsewhere in the Amazon
Because terrestrial and aquatic systems are tightly linked, advances in aquatic research at CCBS will directly strengthen existing forest-based studies.
Expanding Aquatic Research in the Amazon
The lack of comprehensive data on Amazonian aquatic systems ensures that new research at CCBS will be both novel and globally relevant. Planned investments in sensors and scientific instrumentation will support multidisciplinary research, integrating biological, chemical, and physical data—one of the central goals of modern ecology.
With support from organizations such as the U.S. National Science Foundation (NSF), aquatic research at CCBS is expanding into critical areas including:
- Hydroecology and floodplain dynamics
- Nutrient transport and water quality
- Migratory fish and bird ecology
- Drivers of aquatic biodiversity
- Emerging human impacts on freshwater systems
Conservation in Action: The Giant Otter Research Program
One of the flagship conservation initiatives linked to Cocha Cashu research is the giant otter (Pteronura brasiliensis) program.
The giant otter is an Endangered apex predator in Peru’s Amazon Basin, particularly in the Madre de Dios region. Although populations have shown signs of recovery following the ban on the fur trade, new and poorly understood threats have emerged—most notably illegal gold mining and mercury contamination, as well as conflicts with fisheries.
Vision and Objectives
Vision:
Within five years, the program will provide critical insights into how giant otter populations are affected by resource availability, gold mining, and community land use—supporting more effective conservation and regional development planning.
Key objectives include:
