Without Monkeys
there is no paradise


We are fundraising to repair, maintain, and install monkey bridges as vital safe pathways for monkeys throughout Guanacaste, Costa Rica.

The Clean Wave & Salve Monos Community Project

This is a community initiated action to address the loss of critical and unique species in our region and maintain the biodiversity that makes Costa Rica Special. It first seeks to evaluate the routes of passage and connectivity of forest cover in both Tamarindo and Playa Grande for the placement of Monkey Bridges.

These bridges will help the animals that use electric lines to cross to avoid the electric lines and instead use the Monkey Bridges. This project focuses on the Howler Monkey, using it as a flagship species to represent the entire at risk animal community and ecosystem.  

This project is part of The Clean Wave community’s greater mission towards environmental protection within our community of Tamarindo and the greater community of our neighbors in Guanacaste. It is in collaboration with, and in alignment with the mission of the organization SalveMonos.

Sustainable Development Alignment

This project focuses on species such as the Howler Monkey as a way to address the Sustainable Development Goals of Life on Land and Sustainable Cities and Communities.

We take into consideration the social, environmental, economic and political institutional factor, through the management of a focal species such as the Howler Monkey.

We seek to not only reduce our negative impact on the environment but instead have a positive impact on our environment and community as a whole, ensuring harmony between humans and nature in a world where all species can thrive.​

Community Partners

Thank you to our generous partners for their contributions and support in  making waves of change with meaningful impacts.

Howler Monkeys
Are one of the four species of monkeys that live in Costa Rica.
How they live
Howler Monkeys live in troops of 6-45 individuals in the dry forest of Guanacaste
Essential Role
they play an essential role in the local ecosystem and are distinct for their howl, which they use to communicate over long distances.


In accordance with the mission of SalveMonos, this project has expansion potential to the entirety of Guanacaste and even beyond.

More external partnerships with organizations and groups can facilitate this growth into a network of imaging systems studying monkey bridges and the animals that use them.

Playa Tamarindo & Playa Langosta

This study has already started with our initial sponsors!

Playa Grande

This is the preliminary part of the study. The project is about to kickoff.

Howler Monkey

Howler Monkeys (A.palliata palliata) are one of the four species of monkeys that live in Costa Rica.

They play an essential role in the local ecosystem and are distinct for their howl, which they use to communicate over long distances. They live throughout South and Central America, from rainforests to dryland forests, and are even common in edge habitats along mangroves and urban environments.

Howler Monkeys spend the majority of their lives in the trees and require continuous forest canopy for forging of leaves, fruit, and flowers.

They live in troops of up to 60 individuals, traveling together throughout the day as they forge.


The major threat to Howler Monkeys exists in rapidly developing urban environments, most commonly areas gaining attention with international tourists.

This includes Tamarindo and Playa Grande, where development in recent years has led to an environment busy with people and town expansion into previously forested habitat.

These pacific coast communities are contained within dryland forests and lie adjacent to mangroves and estuaries.

What we are doing
about it



Rapid economic development and urbanization, especially for the sake of tourism, is encroaching on native ecosystems and wildlife habitat, notably that of howler monkeys.

Although many aspects of this development present threats to native and endangered species, the rapid building and construction has led to cheap, uninsulated power lines that commonly electrocute tree-dwelling species using the lines to cross roads.

As roads are drawn throughout the country to connect the human landscape, the forested landscape is increasingly fragmented, and tree-dwelling species rely on electric lines to safely cross roads from one forest to the next in search of food.

Thousands of electrocutions occur nationally every year, killing or severely injuring animals and rendering them in need of rescue and rehabilitation. Additionally, these electrocutions often lead to orphan baby monkeys.

They also impact humans by causing power outages and electrical system failures that need repair. 

Because howler monkeys require continuous forest to thrive as a species, they rely on power lines to connect habitat that has been fragmented by roads.

Numbers have declined significantly in recent years, and low genetic diversity puts them at risk of genetic defects and low disease tolerance, further harming the species.

Electrocutions has been deemed one of the most significant threats to the species survival.

Partner organizations

SalveMonos is a community initiated and led, nonprofit organization united to address the disappearance of monkeys in the Guanacaste peninsula.

They look to investigate causes of the problem and create solutions. They envision a world where societies can develop in harmony with the environment, protecting biodiversity and ensuring that every unique species and it’s place in the ecosystem is retained.

They define their mission as to “Protect and rescue the wildlife of Central America, especially monkeys, through actions and mechanisms that reduce the threats to their way of life, creating an appropriate environment for the reproduction of its species and guaranteeing the necessary help to individuals in danger.





Two studies will be conducted to identify howler monkey troops, their ranges, and activity habits within Tamarindo and Playa Grande. This will help us to learn about howler monkey populations, how they move across their landscape, and their feeding behaviors.

This will allow us to  locate areas where new bridges are needed, connecting critical fragmented tree habitats and ensure their population survival.

As urbanization continues, habitat changes, the project progresses, and bridges are implemented, resampling should be carried out to analyze troop behavioral dynamics and effectiveness of bridges.


Monkey Bridges have been designed to facilitate safe crossing of electric lines for howler monkeys and other species.

These bridges consist of insulated power lines and rope “ladders” running across the road. They are build in association with cones or turntables that prevent the animals from using the anchor of the poles to climb, which puts them at risk of electrocution on the transformer.

Proper signage on main roads at wildlife crossings, will raise awareness for their crossing, promote education of the problem, and encourage support for the project.

Existing bridges should be surveyed to identify ones in need of maintenance and repair.


Preliminary study

The proposed total cost of the pilot study is $1800 for each of the two sites, totaling $3600. 

One study will be conducted in Playa Grande, and the others in Tamarindo/Playa Langosta & Playa Potrero

Project and Implementation

The total budget for this project is $44,000

$8,000 – SalveMonos, working capital for ongoing maintenance, new studies, and operations.

$8,000 – TCW, working capital (campaigns, staff, web development, equipment)

$24,000 –  Project costs including 2 studies, current bridge repair, and new bridges

$4,000 – Monkey Foundation for Future bridges and maintenance for the year
