Citizen Trees is an original project by the theater company Organismo Teatro. It consists of an audio-walk experience in which citizens, through a web app, can listen to the sounds and stories of the oldest and most heritage-rich trees in our surroundings. This is a transdisciplinary initiative that blends sound art, theater, arboriculture, and technology, positioning itself within the field of new media.
We work with trees that inhabit urban areas, seeking to reclaim their presence and give them a voice amid concrete and in the midst of hectic, relentless cities. Someone, at some point, chose to plant them there—so listening to the trees in the city also means listening to those who once decided to plant them. Citizen Trees is also an act of remembering—through sound—the history of people doing something for the trees in our cities, and the trees, in turn, doing something for those societies.
Our project has already materialized in three editions: The first was developed in El Bosque (2023), one of the districts with the lowest number of trees in the Metropolitan Region. The second took place in Santiago’s Parque Forestal (2024), focusing on the oldest and most historically significant species in the area. The third edition was carried out in Parque Quinta Normal in Santiago (2025), involving work with the “parents and grandparents” of many other trees across the city—thus, the oldest in the Metropolitan Region. These editions have firmly established themselves among the public, generating a significant and positive impact within the communities.

Since 2010, he has developed transdisciplinary cultural projects that intertwine public art, memory, science, and nature, with a strong focus on civic participation and local engagement. His experience ranges from artistic creation to the formulation, management, and sustainability of initiatives funded by both public and private institutions. He currently leads Citizen Trees, an innovative project that combines art, technology, and natural heritage to connect citizens with the vital and sonic history of Chile’s heritage trees. His work is distinguished by an inclusive, community-based, and long-term approach that understands art as a transformative tool for cultural and social development.
Actor and BA in Performing Arts from Universidad de Las Américas (2014), Nelson is a manager and creator at Organismo Teatro, where he leads creative processes focused on theater and public art. Since 2014, he has built a strong track record in theater pedagogy, working in a variety of educational contexts. In Citizen Trees, he co-leads the initiative alongside director Emerson Velásquez, playing a key role in the management and implementation of its three editions—El Bosque, Parque Forestal, and Quinta Normal. His work focuses on territorial coordination, the design of mediation plans, and strengthening pedagogical and community links, integrating art, education, and civic participation into meaningful cultural experiences.
Journalist and BA in Social Communication from the Pontificia Universidad Católica de Valparaíso, Claudia has over 15 years of experience in content creation and communications within the field of culture and the performing arts. She has been a key contributor to all three editions of Citizen Trees—El Bosque, Parque Forestal, and Quinta Normal—successfully positioning each one within national media outlets. Her expertise has been essential in bringing visibility to the project and generating a communications strategy consistent with its artistic, territorial, and civic identity.
Professional actress and theater educator with over two decades of experience in designing and implementing educational processes through theatrical tools. She has worked extensively in educational settings, leading workshops for children, youth, and teachers, using play, creativity, and active listening as tools for learning and transformation. In Citizen Trees, she coordinates guided mediations and tours, where her playful and sensitive approach opens up spaces for deep connection with the trees, the environment, and the collective experience.
Matías Serrano is a sound artist and academic with training in Media Arts from Universidad de Chile. His work explores the relationship between sound, technology, and the environment, combining mechanisms of sonic experimentation with collaborative practices. In Citizen Trees, Matías has created the sonifications of the trees—sound metaphors that translate each tree's unique features and characteristics into original compositions. These metaphors invite citizens into a deep sensory experience that reconfigures their everyday perception of the urban landscape through sound, fostering new forms of dialogue between people and the arboreal environment.
Rafael Pastene is a musician and composer dedicated to sonic creation across multiple languages, with a particular focus on the performing arts. His career is characterized by a continuous dialogue between music, the body, text, space, and image, exploring collective creation within theater, performance, and dance. Since 2019, he has been a member of Organismo Teatro, where he takes part in research-driven stage processes in which music does more than accompany—it proposes, challenges, and transforms. In all three editions of Citizen Trees, Rafael has been responsible for assembling the audio narratives of the trees, weaving together diverse voices and soundscapes to create stories that resonate deeply with both urban and natural settings.
Developer and Digital Animator with over 10 years of experience in creating digital graphic content across various formats. His career includes a specialization in character design and animation, to which he has recently added strong training in user-centered interface design (UX/UI), having completed the Expert Master's program at CICE in Madrid. In Citizen Trees, Rodrigo is responsible for designing and developing the web app for each edition of the project, creating digital environments that are accessible, intuitive, and aesthetically connected to the artistic and sensory experience we aim to deliver.
In each edition, we carry out extensive research aimed primarily at recovering the traces left by each tree—working under the notion of trees as witnesses and integral parts of the historical memory of our society. First, we develop a process grounded in arboriculture. Through exploration and auscultation of the species present in each territory, we select the tree communities that will form part of the audio-walk experience. In parallel, we work with the concept of the “trace,” documenting every piece of information each tree may share with us—assembling a kind of cartography that maps the life journey of each species.
“Trees are time made visible; in their habits and trunks, we can revisit the history of societies.”.
We then gather historical background information on each area we intervene in. All of this is documented in a series of botanical records that serve as a foundation for the following creative process.
Next, we record the electrical stimuli of each selected citizen tree. Through a sonification process, we transform this data into the unique sound or “voice” of each tree. Later, we create a series of narrative stories inspired by each tree species. These tales are based on the voices, historical background, and individual traces of each tree, and are eventually interpreted by different members of the community.“We aim to produce the sound of the trees in our society—allowing them to be the protagonists, the ones who tell their own stories.”.
Finally, we assemble each audio narrative, bringing together two realms: on one hand, the vegetal voice; on the other, the human voice—merging in a kind of interdimensional dialogue. These human voices, placed in service of the trees, may become powerful tools for fostering possible dialogues with the vegetal world—with the trees of our society, with the citizen trees.
“An old cork oak in Parque Quinta Normal says: ‘I can’t understand you. What could you mean? How much longer until we understand each other? I wish we trees could have that privilege—the one of words—to play with you, releasing them, letting them fly into the air and watching them fade away on cold winter afternoons.”.
What is Árboles Ciudadanos?
We often say it’s a theatrical, auditory experience—where you can listen to the sounds and stories of the trees around us.
Yes, that’s true.
But, Árboles Ciudadanos is also an invitation to lend an ear to the trees of our society.
To listen to a tree is to take responsibility—responsibility for our roots, our history, our memory.
What are trees, if not all of those things?
Listening to a tree is allowing ourselves to be questioned by the tree itself.
How many roots have we wanted to sever?
How much history have we wished to burn?
How much memory have we longed to forget?
We know well that when a tree is cut down, an entire history falls to the ground.
We know well that when a tree dries up, memory fades away.
We know well that when a tree burns, all our roots turn to ash.
The ashes. The fire.
It seems sadly inevitable to speak of fire when we speak of trees.
But it’s also true that fire forces us to imagine, to dream of the day when the fires
consuming every tree may finally be extinguished.
Sometimes, through fire, we can become someone else—something else.
Who ever said that trees were afraid of fire?
Have you ever seen a tree run from the flames?
It’s not the fire that roars—it’s the tree that roars when it burns.
It’s not the fire that roars—it’s the tree that roars when it burns.
A tree knows that here, in this narrow strip of land, life is always lived close to fire.
Sooner or later, everything could burn.
Trees stop fearing the embers.
They learn to sprout with the fire.
Because even if we don’t see them, the ashes always remain—waiting for the wind
to one day rekindle them.
I don’t know why, but it seems, and everything suggests, that in this land there
have always been more embers than roots.
Here, the fires never go out.
If trees are history, then here, history turns into smoke.
Perhaps that is the inescapable fate of a Chilean tree: to live forever on the verge of flames.
Perhaps it is the fate of trees all around the world.
Do the trees have to disappear for the fires to cease?
When did we climb down from the trees only to turn them into bonfires?
To listen to a tree may also be to hear the roar of the scorching fire of history—
demanding that we extinguish all the flames.
But there is always hope for the trees,
because we know that after the fire—everything blooms.
Just like the citizen trees of all our territories.
In each version of the project, we have organized guided tours and mediation activities with different communities.
In El Bosque, we conducted a series of guided tours with neighbors as well as students from schools with high vulnerability indexes in the municipality.
We also coordinated mediated tours for visually impaired participants, invited by Fundación Luz.
In Parque Forestal, we invited older adults, supported by the National Service for
Older Adults (SENAMA) and CEDIAM. Additionally, in collaboration with the
National Museum of Fine Arts, we organized mediation activities with children and
the general public.
Similarly, with the support of Fundación Luz, we held sessions with visually
impaired individuals.
Finally, in Quinta Normal, in collaboration with the Museum of Memory and Human
Rights, we invited audiences from the museum itself and teams from various
memory sites in the Santiago Metropolitan Region, organizing tours based on
themes of memory, human rights, and nature.
Likewise, we held guided tours with the general public, students from emblematic
high schools in Santiago, neighbors from the Yungay neighborhood, migrant
communities, and blind users with Fundación Luz.
Our intention is to sensitively bring our creative processes closer to communities,
while carefully introducing topics and concepts from the diverse disciplines
involved in the project’s creation: arboriculture, ecology, sound art, literature, and
philosophy.
In this way, we open spaces for dialogue, debate, and civic reflection around public
art strategies linked to environmental work, while simultaneously stimulating
interest in transdisciplinary artistic practice and its substantial contribution to the
care and protection of ecosystems.
Each version of our project involves the deployment of different mechanisms that
have allowed us to achieve a positive and significant impact with the public.
On one hand, we implemented a press management plan involving journalists
specialized in culture and environment, positioning each version in both local and
national media outlets.
Similarly, we have worked through strategic alliances with various organizations,
whether governmental, municipal, environmental, cultural, or related foundations
and entities aligned with our work, deploying joint collaborations that have
strengthened the impact and dissemination of each initiative.
On the other hand, we have collaborated with territorial organizations,
neighborhood groups, and residents in each territory, involving them in the creative
and management process of each initiative.
In doing so, we have contributed to the active participation of communities in
artistic processes related to public art, strengthening their relationship with their
own surroundings, fostering a sense of belonging to their natural heritage, and re-
signifying their everyday spaces.
Since its inception, Citizen Trees has been experienced by a diverse audience exceeding 9,000 visitors.
In El Bosque, we reached over 3,300 attendees, including students from high-vulnerability schools, people with visual disabilities, neighbors, and the general public.
In Parque Forestal, approximately 4,059 attendances were recorded, with notable participation from older adults, children, students, visually impaired people, and general audiences.
Finally, for Quinta Normal, we estimate to reach over 5,000 attendees, including educational communities, diverse citizens, and people with disabilities.
“Memory? Memories?
In the head? No.
How could we keep memories in the head?.
Where do we store memories, then?
Right here—everywhere—like a pile of bark.s. That’s where we trees store memories. Layer upon layer.
Sometimes, memory isn’t preserved like a series of images— it grows as a layer, blooming into bodies, into trunks, into trees—like a cluster of bark.””
“Trees are also our memory; their bark holds the record of who we’ve been— trees never forget. So it’s not just about giving a tree the voice of an actor or actress; it’s about placing ourselves in conversation with memory— entering into dialogue with our own history.”

“Árboles Ciudadanos, Quinta Normal” is the third audio walk version, carried out in
2025 in Santiago’s Quinta Normal Park—Chile’s first public park, founded in 1842
and later declared a nature sanctuary in 1976 and a heritage zone in 2009 by the
National Monuments Council.
This time, we worked with some of the oldest trees in Santiago, examining species that are the ancestors of many trees planted in other urban public spaces across the city.
Here in the park, listeners will hear whole societies of trees sounding and speaking simultaneously. That’s what makes Quinta Normal so fascinating.
Given the heritage value of the trees being featured, we are working with a cast of
actors and actresses who are themselves considered part of Chile’s cultural legacy,
whose voices resonate deeply with the character of each tree.
Among them: Héctor Noguera, Luz Jiménez, Naldy Hernández, Rosa Ramírez,
Elsa Poblete, Tito Bustamante, Alejandro Trejo, Rodolfo Pulgar, and Paulina Hunt.
This version of the project is funded by the Ministry of Cultures, Arts and Heritage
(Fondart 2024), with support from Fundación Reforestemos, endorsements from
Sernatur, the Ministry of the Environment, the National Cultural Heritage Service,
collaboration from the Museum of Memory and Human Rights, and Fundación Luz.
