Finca Las Piedras
Finca Las Piedras is the ASA's research and education center in the Peruvian Amazon. Located about an hour north of the city of Puerto Maldonado along the Interoceanic Highway, the site provides researchers, students, educators, conservation professionals, and others access to a variety of Amazonian ecosystems. The site is mostly upland or ‘terra firme’ rainforest dominated by Brazil nut (Bertholletia excelsa) and other tropical hardwoods; Mauritia palm swamps, regenerating secondary forest, and active and abandoned agricultural fields are also within easy reach. The property is bordered to the east by concessions for Brazil nuts and this forest continues, unbroken, for hundreds of kilometers into the Manuripi reserve in neighboring Bolivia.
Living facilities on site include shared dorms and private rooms with mosquito nets, shared composting toilets, open-air cold showers, laboratory space, wifi, and an open-air dining hall where meals are served—all rustic yet comfortable and designed to minimize our environmental impact. A trail network provides access to numerous rainforest habitats.

Host a group at Finca Las Piedras
Finca Las Piedras is an ideal site to host a field course, service learning project, or other group in the southern Peruvian Amazon. Easy accessibility, incredible habitat diversity and good wildlife viewing opportunities, as well as rustic yet comfortable facilities and excellent food ensure a productive and unforgettable experience.
A major advantage of hosting your field course or other group at Finca Las Piedras is that, unlike most other field sites in the region, the ASA maintains active, in-house research projects at the site spanning diverse topics that visitors can get involved with. Our projects include biological inventories of plants and animals ranging from insects, mammals, and birds to trees, orchids, and other plants, phenology monitoring of Brazil nuts and aguaje (Mauritia) palms, and sustainable tropical agriculture, agroforestry, and reforestation. Experienced ASA staff are always available and happy to help coordinate logistics, plan academic programs, and organize field activities, both in advance and once in the field, at Finca Las Piedras and throughout the Cusco and Madre de Dios regions. Contact us for more information about how we can facilitate your stay in Peru.
Finca Las Piedras is located in the Madre de Dios Department of osoutheastern Peru, where the Andes Mountains meet the vast Amazon basin.
Madre de Dios is among the most biodiverse regions on the planet—more than 1,300 species of butterflies alone have been recorded to date.
Finca Las Piedras is the ASA's research base in Madre de Dios, and provides access to varied Amazonian habitat that shelter more species of plants and animals than anywhere else on earth.
Most of the site is covered in upland, 'terra firme' rain forest. Bertholletia excelsa—the source of Brazil nuts—is a dominant canopy species.
Orchids comprise the most diverse family of plants in the world and are especially abundant in the rainforest canopy at Finca Las Piedras.
Students on a field course help plant native trees for reforestation in the ASA shadehouse.
Seedlings of copoazú,Theobroma grandiflorum, grow in the ASA's shadehouse. This is one of numerous native species that we are working with to enhance the biodiversity value of the rain forest-agricultural matrix that surrounds us.
