Manu Biodiversity Expedition!




The Gallito de las Rocas conservation area is located in the heart of the most biodiverse region of the planet, where the towering Andes mountains meet the sprawling Amazon basin in Southeastern Peru, near Peru's world-famous Manu National Park. However, despite the region's unmatched biological wealth, we still do not know exactly how many species can be found here. And further, we know almost nothing at all about the biology of most species—for example, how abundant are they? Which species are declining, or being driven to extinction because of climate change? At present we are unable to answer these questions, yet this knowledge is increasingly important as people drive unprecedented change in the rainforest. The goal of this expedition is to fill in major information gaps at Gallito de las Rocas, allowing us to create a long-term plan to manage and protect the area's unmatched biodiversity.


Participation in this expedition is open to all those interested in tropical biodiversity and field biology. Our focal groups will include Lepidoptera (butterflies and moths), birds, mammals, and herpetofauna (reptiles and amphibians). Surveys will be directed by team leaders who are an experts in the field, and each team will focus on surveys of its respective taxonomic group using both traditional and cutting edge surveying tools and techniques. Participants may commit to a single team or assist any combination of the four.

Participants will:


Expedition participants will help with all aspects of surveys and will gain hands-on experience in biodiversity sampling design and setup, as well as the collection and management of biological field data, all in one of the most beautiful and biodiverse places on earth.

Through your participation we hope to gain not only the muscle needed for survey work in our challenging conditions, but also to spread awareness of the conservation challenges facing the Manu region and train the next generation of tropical biologists and conservationists.

Research Objectives & Methods

Research Objectives & Meth.
Lepidoptera team

Lepidoptera team

(Butterflies & moths)


The Lepidoptera team will focus its surveys on two groups: butterflies that are active in the day and moths that are active mostly at night. For butterflies, the team will employ a variety of methods including baited traps, strategically-placed baits of other types such as rotting fruit and spit wads (for skippers), and hand nets for species that don’t typically visit bait. Moths will be sampled at night using an LED light setup that is designed

specifically to attract insects. This will not only draw in an impressive number and variety of moths but also an incredible diversity of other invertebrates.


All knowledge gained by the Lepidoptera team at Gallito de las Rocas will contribute to ongoing efforts to document regional butterfly and moth species diversity and natural history. With more than 1,300 butterfly species known from just a single site in Manu National Park (essentially the only site in Manu that has been well-studied), the team certainly has its work cut out for itself!

Bird team

Bird team


The bird team’s main goal is to document patterns in avian species richness and abundance along a 500-meter elevational gradient in the Gallito de las Rocas conservation area. This is done in three ways: first, the team will conduct point-count and walking-transect surveys to look and listen for birds. Second, since many rainforest species are cryptic and difficult to detect with standard aural-visual surveys, the team will also deploy mist-nets to

capture and band birds, further allowing us to track individuals over time and learn more about the relationships between life history, survival, and local movements. And finally, ARUs—autonomous recording units—will be deployed in the forest to record bird calls that can be identified and analyzed later. ARUs are advantageous because they can detect birds, including cryptic species, over long periods of time, greatly increasing our effective sampling effort.

Very little is known about the distribution and abundance of birds in the Manu region—and almost nothing regarding the biology of most species—so we are well-poised to make important discoveries regarding bird biology at Gallito de las Rocas during this expedition, and also as the study continues into future years.


With over 1100 species registered in Manu National Park, the team can expect to have their surveying and identification skills put to the test, yet they will be rewarded by some of the best birding anywhere in the world.

Mammal team

Mammal team


In addition to traditional aural-visual surveys for species such as monkeys, the mammal team will employ two other techniques. First, camera traps will be deployed throughout the forest, which will allow us to document larger yet cryptic species such as cats (jaguar, puma, ocelot, etc.), Andean bear, tapir, peccaries, and many others. Additionally, given that most tropical mammals typically are bats, these animals will be surveyed at

night using acoustic monitors to listen in on ultrasonic bat calls and mist nets, including in the forest canopy, to catch and release bats. Thus, the mammal team will work hard, day and night, to gather distributional records but will be rewarded with exciting discoveries of a diversity of both Andean and lowland Amazonian species.


Mammals are vital components of rainforest ecosystems, for instance as one of the most important of the forest's seed dispersers. Documenting the composition of the mammal community at Gallito de las Rocas, therefore, is an important first step in understanding the dynamics of the rainforest and the role these animals have in the processes that keep it healthy and high in biodiversity.

The bulk of the mammal team's activities will concern bats, including capturing them with mist nets for the purpose of identification. In order to handle bats participants are required to show proof of a pre-exposure rabies vaccine or titre administered within 4 years of the expedition start date. Non-vaccinated participants may help in all other aspects of the mammal team's activities, except for bat handling.

Herp team

Herp team

(Reptiles & amphibians)


Surveying reptiles and amphibians is relatively straightforward but, due to the cryptic nature of many species, long hours are required to build a site inventory. Thus, the herp team will spend significant time in the jungle searching for frogs and snakes, especially at night, when these animals tend to be most active. But, no fear, this effort will be greatly rewarded with a unique mix of both Andean and Amazonian species. The herpetofauna of Gallito de las Rocas has not been

extensively assessed, so we are sure to have some exciting finds and new records!


Tropical reptile and amphibian species are facing serious threats, including habitat loss and declining populations due to illegal trade and disease. In particular, the fungal pathogen Chytridiomycosis has taken a major toll on amphibian populations worldwide, including in Peru, with many species in critical decline or even extinct as a result of the disease. Unfortunately, during our first expedition to Gallito de las Rocas in 2018 we detected the chytrid fungus in several amphibian species. Data gathered by the herp team, therefore, will be useful in understanding both the impacts of this and other threats over time, as well as how we can protect as many of these unique species as possible.

Expedition Details

Gallito de las Rocas is a 10,000 ha (~25,000 acre) privately-managed conservation area in Peru's Cusco Department, near Manu National Park and Biosphere Reserve and right where the towering Andes Mountains meet the sprawling Amazon basin. The concession is mountainous and covered mostly in dense primary rainforest that is drained by many small streams and larger rivers. Ranging from approximately 800-2,000 masl (~2,600-6,500 ft) the area's flora and fauna is a unique mix of Andean and lowland Amazon species—here, Andean spectacled bears and Amazonian jaguars roam the same forest, along with a dizzying variety of other lifeforms both large and small.


After meeting in the city of Cusco (capital of the department of Cusco) we will work our way overland down to the Andean foothills at Pillcopata, and then by foot deep into the jungle of the Gallito de las Rocas concession. After concluding field work in Gallito de las Rocas the team will return to Cusco, where the expedition will conclude.
