The first sustained contacts between the Matsés and outsiders happened in the 1960s, and they were not peaceful. The Matsés, who had watched Westerners push into their forests, responded with bows and arrows, raiding settlements and taking women from neighboring villages. The Peruvian government responded with aircraft. Villages were bombed. Survivors were forced toward the Brazilian border, where eventually the government granted them the first indigenous territorial reserve in Peruvian history. That was the beginning of an uneasy arrangement. More than half a century later, the Matsés still live in these forests, and the land around their villages is now protected as the Matsés National Reserve - 4,206 square kilometers of some of the most biologically intact lowland forest in the Amazon.
Unlike most protected areas in Peru, the Matsés National Reserve did not originate in a government plan or an NGO blueprint. In 1994, the Matsés Native Community themselves, supported by the Peruvian NGO CEDIA, asked the Ministry of Agriculture to create a communal reserve that would guarantee them access to the forests and rivers they depended on for food. The request sat for thirteen years. The government neither approved it nor explained why. Then in October 2007, three letters from Peru's state petroleum agency PerúPetro changed the calculus: oil concessions were about to be signed on land the Matsés had been asking to protect. The community drew a line - no companies would enter until the state responded. In 2009, Supreme Decree 014-2009-MINAM finally established the reserve.
The reserve sits in the Loreto Region of the Peruvian Amazon, sharing a long border with Brazil. Taken together with the Sierra del Divisor National Park in Peru and the Alto Juruá and Alto Tarauacá Extractive Reserves in Brazil, it forms a bi-national biological corridor of several million hectares. That matters because jaguars, harpy eagles, and other wide-ranging species do not recognize political boundaries. Ecologically connected protected areas give large animals the space they need to maintain genetic diversity and respond to long-term climate change. The Matsés territory is the northwest anchor of this corridor.
In November 2004, a team from Chicago's Field Museum joined Peruvian institutions - including the Universidad Nacional de la Amazonía Peruana, CIMA, and CEDIA - for a two-week rapid biological inventory. The results were staggering even by Amazonian standards. 177 fish species, ten new to Peru, eight possibly new to science, with an estimated total of over 300. Forty-three species of large mammals documented, with large primates occurring at high densities and threatened species showing no signs of hunting pressure. 74 amphibian species registered, including a possibly new Dendrobates poison frog and a Synapturanus representing a genus never before recorded in Peru. 416 bird species, including two specialists of white-sand forests, one possibly new to science. The team estimated 550 total bird species were likely present.
Among the most remarkable discoveries were large extensions of varillal - white-sand forests - which are exceptionally rare in the continental Amazon and even rarer in Peru. These forests grow on nutrient-poor quartz sands, and their poverty forces strange evolutionary outcomes. Species diversity is low, but endemism is extraordinarily high: plants and animals adapted to white sand cannot compete on richer soils, so they speciate in isolated pockets and stay there. The Matsés Reserve contains some of the largest protected white-sand forests in the country. Botanists cataloged 1,500 plant species during the survey, many new to Peru and to science, and estimated total flora at around 4,000.
The Matsés number around 3,200 people divided between Peruvian and Brazilian communities. They speak Matsés, a Panoan language, and their traditional knowledge of the forest is both encyclopedic and still being transmitted. Matsés hunters know which tree frogs carry skin secretions used ritually to sharpen focus and clear the body (a preparation called kambô). They know which fish move when in which stream. They can read animal tracks the way most people read text. The reserve's co-governance model recognizes that protecting biodiversity here means protecting the Matsés relationship to the land - not as a museum exhibit, but as an active, continuing stewardship that has kept these forests functional while so much else of the Amazon has been cleared.
The Peruvian Amazon has lost enormous areas to cattle, coca, illegal gold mining, and petroleum infrastructure. The Matsés reserve is important not only for what it contains but for what it demonstrates. Indigenous communities have, in many parts of the Amazon, proven to be the most effective long-term conservators of forest when their land tenure is secured. The Matsés spent thirteen years asking the state to protect what they already protected. When the state finally acted, it acted in large part because the Matsés themselves refused to let oil companies in. The reserve exists because a community decided their own forest was worth standing in the way of the machinery of extraction. The jaguars, the frogs, the white-sand forests - all of them benefit from that decision.
Located at 5.73°S, 73.37°W in the Loreto Region of the northeastern Peruvian Amazon, near the Brazilian border. The reserve covers 420,635 hectares of lowland rainforest, mostly below 300 meters elevation. Nearest airports are Iquitos (IQT/SPQT) to the north and Pucallpa (PCL/SPCL) to the south, with smaller strips at Colonia Angamos. Recommended viewing altitude 3,000-8,000 feet AGL. Expect dense cloud cover in the wet season; dry season (June-September) offers clearer visibility of forest canopy and major rivers (Yaquerana, Gálvez).
