Research Objectives

We will focus our work on three taxonomic groups. Expedition participants can assist in one, all, or any combination of groups that suits their interests. Scroll down to read about them.


Insect diversity and biology

The ASA has several ongoing projects related to insect diversity and biology in southeastern Peru, and our expeditions further the goals of these long-term projects. In particular, we focus on the order Lepidoptera, which includes butterflies and moths. We will document the butterfly and moth species present in the study area, collecting butterflies by day using hand nets and baited traps placed in the rainforest canopy, and sampling moths at night using a portable LED light setup. We will also search for butterfly and moth caterpillars and rear them to adulthood in our field laboratory, to document species' host plants. You can read more about our work with Lepidoptera in Peru and our research progress and publications here.


In addition to Lepidoptera, we will also sample insects in other groups ranging from beetles to ants to true bugs and Orthoptera (crickets and grasshoppers), among others, using a variety of field sampling techniques across a range of Amazonian ecosystems found at the study site. The diversity of insects in our region is staggering, so we will have our work cut out for us!


Reptiles and 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, we will spend significant time in the rainforest searching for these animals, especially at night, when they tend to be most active. Tropical reptile and amphibian species are facing serious threats, including habitat loss and declining populations due to illegal trade and disease (e.g., Chytridiomycosis). Data gathered during the expedition will provide important baseline information to monitor changes in populations over time as these threats grow. Although the study site has not been explored, target species which we hope to find include green anaconda and several other species of boas, bushmaster, other viper species, caiman, turtles, and, of course, a large diversity of frogs and other amphibians.



We will survey these animals using two methods. First, we will document primate diversity and abundance by patrolling trails and transects within the study area. Target species include howler monkeys, two species of capuchins, squirrel monkeys, tamarins, and night monkeys, among others. Second, we will deploy camera traps at strategic locations to document more elusive species such as jaguar, puma, giant anteater, short-eared dog, giant armadillo, ocelot, and white-lipped peccary. We expect all of these species and many more occur within the study area, but without any sampling their presence remains to be confirmed. We will be the first biologists to do so, establishing a baseline inventory of the site from which changes in populations over time can be monitored.

Peru's Madre de Dios region, located in the country's extreme southeastern corner, is home to some of the largest expanses of pristine rainforest remaining anywhere in the Amazon. Roughly half of the region's forests are protected for the conservation of biodiversity and other natural resources, including Brazil nuts (Bertholletia excelsa), which are harvested sustainably across more than one million hectares of natural rainforest in Madre de Dios. We will travel to the end of a road that provides access to a large area set aside for Brazil nut extraction, where other activities that are devastating much of the rest of the Amazon—logging, gold mining, and cattle ranching, to name a few—are not permitted. As primary, undisturbed rainforests become ever more scarce throughout Amazonia, a better understanding of their biodiversity and how intact plant and animal communities function is of increasing importance. If we know how a rainforest ought to look, for instance, as well as what species it ought to contain and in what numbers, we will be better able to restore degraded areas to their ideal state. The data that we will gather during our expeditions, from primary rainforests that have been almost untouched by humans, will help us to better protect species and conserve biodiversity as the threats posed by human activity grow throughout the Amazon.

The study site is covered mostly in upland, 'terra firme' rainforest where the dominant emergent trees include Brazil nut, ironwood (Dipteryx micrantha), and ana caspi (Apuleia leiocarpa), among many other species. These emergents tower over the rainforest canopy and are found here in great numbers, whereas they are declining in most other areas due to illegal and unsustainable logging and conversion of rainforest to agriculture. There is also an 'aguajal' within easy access, which is a unique Amazonian wetland ecosystem that is dominated by the palm tree Mauritia flexuosa, known locally as 'aguaje'. These palms form dense stands that are an important resource for nesting blue-and-yellow macaws, a variety of large mammals including howler monkeys, and a large yet unknown diversity of terrestrial and aquatic insects, other invertebrates, fish, reptiles, and amphibians. We will have the opportunity to explore these diverse Amazonian ecosystems by foot and by water, allowing us to sample an incredible number and variety of unique plant and animal species found nowhere else on Earth.

Expedition Itinerary

Day 1. The team meets in Puerto Maldonado, the bustling capital and economic hub of the Madre de Dios region. In Puerto Maldonado we'll have the chance to pick up last minute supplies before heading to our base camp, Finca Las Piedras. Overnight at Finca Las Piedras. 

Day 2. Finca Las Piedras is the ASA's home base in Madre de Dios, and it is here that we'll get our first introduction to the rainforest and the techniques used to study biodiversity in the Amazon. We'll also use this time to make final preparations for the next day's expedition further into the jungle. Overnight at Finca Las Piedras.

Day 3. From Finca Las Piedras we'll travel to the end of a rough road used to take Brazil nuts out of the rainforest. This will be our base camp, miles from the nearest town, shop, or house, from where we will explore the rainforest, its different ecosystems and myriad plants and animals. We'll set up our tents, get settled into the remote jungle, and get to work! Overnight in our tents at the remote expedition site.

Days 4-8. The field work continues. Since we'll be studying different groups of animals during both day and night, we will organize our time so that everything gets done and everyone is contributing to the project or projects they have the greatest interest in. We'll be hunting for butterflies and scanning the canopy for monkeys in the day, walking the rainforest at night to search for reptiles and amphibians, and spending every minute possible searching for too many things than can be listed here. Nights spent in tents at the remote expedition site.

Day 9. With our work finished, we’ll retrace our steps back to Finca Las Piedras to clean off our gear, sort through our specimens, enter data, and organize photos and videos. Tonight we will have a farewell dinner as a group and reflect on our experience in the rainforest. Overnight at Finca Las Piedras.


Day 10. With the expedition concluded we will make sure each participant makes it to the airport for their flight home or onward travel.

What's Included

The expedition fee covers all project-related local transportation and all accommodations, including transfer to and from the airport (or bus terminal) in Puerto Maldonado, all other transportation to and from the expedition site, all lodging (lodging at Finca Las Piedras, as well as a basic campsite at the expedition location), and all food (3 meals per day). All field equipment related to biodiversity surveys (insect traps and nets, specimen storage equipment, GPS units, etc.) will also be provided.

What's Not Included

The fee does not include meals in Puerto Maldonado (if arriving early), international or domestic airfare (i.e., from your home country to Lima, and then on to Puerto Maldonado), or personal expenses in Peru (e.g., souvenirs, alcoholic beverages, etc.). Personal gear and equipment, including tents or other camping gear, binoculars, etc., are not provided. Medical expenses, including travel/medical insurance that covers you in Peru (required), as well as any costs associated with medical care and/or evacuation in Peru, are also not covered by the Expedition Fee.


The first two nights of the expedition, as well as the last, will be spent at Finca Las Piedras, the ASA's rustic yet comfortable home base in the Peruvian Amazon that has shared rooms, shared composting toilets and showers, a screened dining hall, and WiFi. The remaining nights will be spent camping at a remote site with very basic facilities. Expedition participants should each plan to bring a tent (or share with another participant), a sleeping pad, and a light sleeping bag. Meals will be cooked for us at the campsite and we will eat under the rainforest canopy and a brilliant jungle night sky.

Important Information Regarding Covid-19

The health and safety of participants in our programs is of extreme importance to us. We have adopted a number of measures to minimize the spread of the novel coronavirus at our facilities and on all of our programs that are based on guidelines provided by Peruvian and international health organizations, including the Peruvian Ministry of Health, the WHO, and the U.S. Centers for Disease Control and Prevention. These measures include social distancing and sanitation protocols, among others, and will be in place during all expeditions.

We also understand that the rapidly evolving situation makes planning difficult, especially in terms of travel arrangements. To accommodate this uncertainty we have temporarily relaxed our normal requirements for payments and registration deadlines. Until further notice participants will be able to pay the full balance of their program by up to two weeks before its start date. We have temporarily waived the normally-required application fee. Please read our Terms and Conditions for further details.

Frequently Asked Questions

Am I eligible to participate?

In order to join the Expedition you must 1) be at least 18 years old (unless accompanied by a parent or guardian); 2) have proof of medical and travel insurance that covers you in Peru; 3) be in excellent physical condition; 4) have a valid passport or ability to travel to/within Peru. No formal training or education is required; we invite people from all background to assist our biodiversity surveys. However, a healthy curiosity for tropical nature, a positive attitude in the face of challenging field conditions, and a willingness to work with people from a variety of backgrounds to achieve a common goal are essential.

How do I get there?

The Expedition begins and ends in the city of Puerto Maldonado, the capital city of Peru's Madre de Dios region. There are two ways you can travel to Puerto Maldonado: overland (i.e., by bus) or by air. A bus from Cusco takes about 10 hours and there are options to travel by day or overnight. The trip is also possible by bus from Lima, but the Lima-Cusco route adds an additional 20-25 hours of travel time. If coming by bus, we recommend either Cruz del Sur, Movil Tours, or Tepsa; these are the most reliable companies that have service to Puerto Maldonado and they have the best safety records. A direct flight from Lima is about 1.5 hrs; from Cusco it is about a half hour. The Puerto Maldonado airport (PEM) is normally serviced by Latam and Sky Airlines, both of which have daily flights from Lima, with or without a stopover in Cusco; more daily flights are available from Cusco. You may be able to purchase a ticket to Puerto Maldonado from your international point of origin on a major international carrier, but at least the domestic legs of your trip (Lima-Puerto Maldonado or Cusco-Puerto Maldonado) will be operated by one of these local airlines.

Do I need a visa to enter Peru?

Citizens of the United States do not need to apply in advance for a visa to enter Peru for stays of 90 days or less; a visa will be granted at the international airport in Lima upon entering the country (or at the border with a neighboring country if entering overland). Requirements for citizens of other countries vary, and we recommend that you check these with the website of your country’s embassy in Peru.

What about money in Peru?

Peru’s currency is the Nuevo Sol, usually referred to simply as the ‘Sol’ (plural ‘Soles’). The exchange rate as of May 2020 was about S/. 3.4 to US$1, and this has been relatively stable for several months. ATMs are available in most major Peruvian cities, including Puerto Maldonado, many of which dispense either soles or US dollars. You will receive a slightly better exchange rate at a currency exchanger (available in Puerto Maldonado) than at an ATM when withdrawing Soles. We recommend that you avoid changing money at airports except for a small amount that you'll need to get through the airport, as the rate will be fairly poor. How much money you will need while in Peru (and not on the Expedition) will depend on your taste and spending habits. As a rule, you can eat a meal at a nice restaurant in Puerto Maldonado for about $10-15 (S/.30-50); cheaper places (e.g., set lunch or ‘menu’ restaurants) will obviously be much less. Prices for hotels also vary—backpacker hostels may charge S/.25 per night, whereas nicer hotels will charge as much as S/.150-200 per night; high-end tourist lodges in the jungle might be as much as $100- 300 per person, per night.

What's the weather like?

The Expedition takes place entirely in the lowland Amazon rainforest during the region's annual rainy season. It rains quite a bit during this time of year, but by no means is it prohibitive. When the sun is out temperatures may reach 30°C (88 °F), although under the shade of the canopy inside the forest temperatures tend to be more pleasant. When it is raining and at night the temperature may drop to 20°C (68°F). Expedition participants should be prepared for rain and shine, heat and relative cool, all of which can change quickly.

What kind of clothing and gear should I bring?

We will provide all of the gear and equipment that will be used for our field surveys (e.g., collecting and surveying equipment, etc.). Everything else is your responsibility. The Expedition involves camping in the rainforest, thus there are several items that you will have to bring with you in addition to your clothes, toiletries, etc. Each team member must have a tent (or arrange to share one with another participant), a sleeping pad, and a light sleeping bag or something else to sleep with, as well as a headlamp and several other items. We will provide a complete packing list once you've registered for the Expedition.

How do I stay healthy in the rainforest?

Despite some of the stories and exaggerated tales from past explorers in the Amazon, the rainforest is not as dangerous or scary a place as many people think. Today, the vast majority of visitors enjoy a completely safe and healthy stay. Nevertheless, we take the safety of our team members very seriously and offer a number of recommendations to help ensure that you have a safe and enjoyable time in Peru. Perhaps the greatest nuisance to humans in our study region is posed by biting insects, including mosquitos and biting sand flies. These are also the vectors of several rare, but potentially serious, tropical diseases. Malaria, Dengue Fever, the Zika virus, Yellow Fever, and Leishmaniasis are all rare but present in the Amazon. We recommend that you discuss your travel plans with your medical doctor for specific recommendations of which vaccinations and/or prophylaxes to take.

What's a typical day like in the field?

Most days start early (e.g., breakfast at 6 or 7 am), so that we can make the most of the shorter tropical daylight hours for surveying biodiversity. Those who would like to go birding will want to start even earlier, as bird activity peaks just after sunrise. Those interested in assisting witih our surveys of reptile and amphibian species will spend lots of time in the rainforest at night, so will require a bit more time to sleep in. Breakfast tends to be a bit more flexible, and we usually have lunch and dinner together as a group, around 1pm and 6pm, respectively. In between meal times is when we conduct the bulk of our work. Each participant's experience will vary depending on their interests and the activities they wish to participate in, but everyone will definitely spend a significant amount of time exploring a variety of habitat types to survey biodiversity.

What's the food like in the field?

Food at Finca Las Piedras is fresh, varied, and delicious, and meals are served three times per day in our screened dining hall. At the remote expedition camp we will eat slightly more basic food, but it will be good and plentiful. We take meals very seriously when in the rainforest--field work is hard and we will work up a big appetite! We are happy to accommodate any special diets or food restrictions with advanced notice.

What is phone and internet service like?

There is good cell coverage in Puerto Maldonado (discuss international rates and plans with your home carrier). At Finca Las Piedras there is WiFi and limited cellular reception (only the carrier Claro). Once we depart for our remote expedition camp there will be no cell or internet coverage at all. This is a time to disconnect and immerse yourself in nature!

How do I do laundry?

Puerto Maldonado has tons of cheap laundry services available. In the field, we wash clothes by hand and dry them in the sun. We recommend that you bring laundry soap (preferably biodegradable) with you. Otherwise, you can purchase soap and/or detergent in Puerto Maldonado.

What about Covid-19 in Peru?

Covid-19, the disease caused by the novel coronavirus, is present in Peru as it is in most countries across the world. As of 26 May, 2020 the country is in partial lockdown aimed at containing the spread of covid-19 and is currently working to relax restrictions in a controlled and safe manner. As of this date most non-essential vehicular travel is prohibited, including local and national public transportation, and most shops and restaurants are closed except for delivery/takeout. As this situation is rapidly evolving, we will maintain registered Expedition participants informed of imporant covid-19-related developments with regular email updates. The health and safety of our Expedition participants is our highest priority in running the program, and we are complying with all relevant recommendations by the Peruvian government, the U.S. Centers for Disease Control and Prevention, and the World Health Organization to keep visitors to our facilities and participants in our programs as safe as possible. More information about covid-19 and how you can protect yourself and others is available at the following links: U.S. Centers for Disease Control and Prevention (CDC) World Health Organization (WHO)
