🌿 The rainforest and Nukini biodiversity
The rainforest where the Nukini people live is organised around water. The river Môa and the network of igarapés that cross the territory create a living structure that shapes the landscape and accompanies the life of the community. In this part of the Alto Juruá, the forest harbours watercourses, humid banks, paths and areas of dense vegetation that connect houses, fishing grounds, cultivation areas and spaces of daily transit.
The igarapés and smaller watercourses also fulfil an essential function within the territory. They mark routes, facilitate movements and help distribute life across the space. Thus, the Nukini rainforest appears as a network of water channels, vegetation and inhabited clearings, where each stretch of landscape links to the next.
This environment combines dense tropical forest and open tropical forest — two forms of rainforest that coexist within a single region and give the territory a great richness of textures, light and natural rhythms. The constant presence of water maintains humidity, feeds the vegetation and sustains an enormous variety of life forms.
🏔 The Serra do Divisor and one of the richest regions of the Amazon
The Nukini rainforest extends into the Serra do Divisor, one of the ecologically most important regions of the western Amazon. This mountain range modifies the relief of the area and breaks the image of a completely flat forest; hills, slopes, winding watercourses and vegetation that adapts to them appear.
The surroundings of the Serra do Divisor form part of one of the great mosaics of protected areas in the southwest Amazon, where indigenous lands, extractive reserves and the Serra do Divisor National Park itself converge. This combination makes the Nukini territory a zone of enormous ecological value, where the richness of the forest interweaves with the historical presence of native peoples who have lived there for generations.
🐒 Fauna, water and the balance of the territory
The richness of the Nukini rainforest is also expressed in the diversity of its fauna. The surroundings of the Alto Juruá and the Serra do Divisor harbour a great variety of mammals, birds, fish, reptiles, amphibians and insects, forming one of the most complex biological landscapes of the Brazilian Amazon. In this region one can find animals such as the tapir, the white-lipped peccary, the collared peccary, the agouti, various species of monkeys, forest birds and a rich aquatic life linked to rivers, lakes and streams.
Water plays a decisive role in this balance. The rivers, lakes and igarapés sustain fish, attract animals, feed the vegetation and keep an essential part of the ecosystem in motion. In a territory like the Nukini’s, fauna and the hydrographic network are linked in a continuous way: where there is water, there is also circulation of life, food, shade, humidity and refuge.
This animal richness becomes clearer when one observes the relationship between all the forms of life that inhabit the forest. The deep forest, the water, the relief and the fauna form a system where each element influences the other.
🌱 Biodiversity as the foundation of Nukini life
For the Nukini people, the biodiversity of the territory holds a value that goes far beyond a general idea of natural wealth. The forest, the rivers and the variety of life forms sustain fishing, hunting, gathering, agriculture and the daily knowledge of the environment. In this sense, biodiversity forms part of the material foundation of the community and directly accompanies their way of inhabiting the rainforest.
This relationship also has a deep cultural dimension. The continuity of the people depends to a great extent on the territory preserving its balance, because in the rainforest are found the animals, the plants, the waterways and the knowledge that shape Nukini life. The forest offers sustenance, orientation and memory, and transmits a form of knowledge that passes from generation to generation.
For this reason, in the Nukini case, to speak of biodiversity is also to speak of territory, continuity and shared life. The rainforest forms an inseparable part of the community. In the water, in the animals, in the density of the forest and in the diversity of the landscape one recognises one of the firmest foundations of Nukini life in the Alto Juruá.
The rainforest during the day 🌿
When day breaks over the Nukini territory, light pierces the canopy of the Amazonian forest in oblique beams that illuminate giant leaves, moss-covered trunks and humid paths connecting the villages to the rivers. The air brims with humidity and tropical heat, and every movement within the forest reveals a presence: the flight of a scarlet macaw, the silent leap of a monkey between the branches or the slow movement of an iguana seeking the sun on a fallen trunk.
The paths walked by the Nukini traverse a plant landscape of extraordinary complexity. Lianas descending from the canopy, palms laden with fruit, roots emerging from the ground like natural sculptures and giant trees that sustain the entire forest system. Between these layers of vegetation flow small streams that eventually feed the river Môa, the main artery of the territory.
In this green, humid world, every step forms part of a continuous relationship with the rainforest. The forest provides food, fibres, resins, medicines and spaces for hunting or fishing, and at the same time sets the rhythm of daily life.

The Nukini rainforest at night 🌙
When the sun disappears behind the forest, the Nukini territory changes character. The temperature drops slightly, the humidity becomes more perceptible and the sounds of the forest begin to reorganise. Insects, frogs and nocturnal birds create a continuous soundscape that extends along rivers, gorges and forest clearings.
In the Amazonian darkness, many species that remain discreet during the day begin their activity. The jaguar silently roams the forest paths, night monkeys move between the branches and small mammals explore the leaf-covered ground. At this moment, the rainforest reveals another dimension of its life: quieter, more attentive and profoundly active.
The Nukini villages then remain surrounded by this nocturnal world where every sound carries meaning. The crack of a branch, the movement of water or the distant call of a bird form part of the everyday landscape of the forest. In that dense, living environment, the rainforest continues breathing as a complete system where territory, fauna and community share the same space.
