Kéköldi Rainforest Project
Community-led rainforest and wildlife monitoring in the Kéköldi Indigenous Reserve of Caribbean Costa Rica.
About Kéköldi Rainforest Project
Operating since 2005
The Kéköldi Rainforest Project runs a long-term biodiversity monitoring programme in the Kéköldi Indigenous Reserve, generating scientific data to support the conservation of one of Costa Rica's most biodiverse Caribbean lowland rainforests. Work is based at a research station reached by a 45-minute uphill forest trail, with the team surveying the reserve almost daily across several taxonomic groups.
Methods include line transects, point counts, audio and visual encounter surveys, camera traps and citizen-science apps. Data feeds species checklists and studies of distribution and co-occurrence that inform conservation decisions, and the work is carried out in close partnership with the Bribrí Indigenous community whose land it is based on.
Its objectives are to increase knowledge of the Kéköldi forest, provide data to conservation partners, build local capacity for long-term conservation and sustainable development, minimise its own environmental impact, and raise public awareness of Costa Rica's forest and coastal environments.
- Kéköldi is one of the top three sites in the world for monitoring migratory birds and hosts the third-largest raptor migration on the planet.
- The reserve covers over 8,500 acres (~3,500 ha) of Caribbean lowland rainforest, home to thousands of species.
- Four wild cat species live in the reserve — puma, ocelot, jaguarundi and margay — with camera traps also watching for the jaguar, absent for around two decades.
- Around one hundred species of frogs and reptiles inhabit the reserve, including the eyelash palm pitviper, fer-de-lance and red-eyed tree frog.
- Monitored endangered species include the critically endangered great green macaw, hawksbill turtle, striped pygmy snake and Central American spider monkey.
- The project built a purpose-built 'Kéköldi Surveys' mobile app for field data collection and produced a documentary about the reserve, 'Sibo's Gift'.
Project work
Raptor migration & biodiversity monitoring
The Kéköldi Rainforest Project runs long-term biodiversity monitoring across the Kéköldi Indigenous Reserve, one of the top three sites in the world for migratory birds of prey. Daily surveys track raptor migration, wild cats, herpetofauna and mammals to build scientific data that supports protection of this Caribbean lowland rainforest.
Community-led & ethical
The project operates on Bribrí Indigenous land with the community's permission, sharing accommodation with a Bribrí family who have lived in the reserve since 1977. It supports community-led initiatives including the Kéköldi Hawkwatch raptor-monitoring work, and respect for local knowledge, culture and safeguarding is built into its code of conduct.
Impact
The Kéköldi Rainforest Project runs long-term biodiversity monitoring and conservation across the Kéköldi Indigenous Reserve and the Cahuita coast in Costa Rica.

Approach
This organisation runs a long-term biodiversity monitoring programme in an Indigenous rainforest reserve, generating scientific data that supports the protection of one of Costa Rica's most biodiverse Caribbean lowland forests. It works in close partnership with the Bribrí community whose land it is based on, aiming to build local capacity for conservation and sustainable community development, provide data to conservation partners, and raise public awareness of endangered species.
Work aligns with UN Sustainable Development Goals 13, 14, 15 and 17 and supports existing community-led initiatives. The research station is run on solar power with rainwater harvesting, composting, tree planting and a largely plant-based diet, and the project measures and minimises its own environmental footprint on the forest.
Milestones
The organisation's conservation work in Costa Rica dates to 2005, when it began in partnership with Tortuguero National Park, spending around 12 years monitoring biodiversity and sea turtles in the Tortuguero area (including green and leatherback turtle work, jaguar camera-trapping, and bird and biodiversity surveys, with results presented at regional and international symposia). In July 2022 the work relocated south to Cahuita to expand conservation and community efforts, and in September 2022 the team began collaborating with the Kéköldi community to support its migratory-raptor monitoring. In December 2022 the base moved into the Kéköldi Indigenous territory to develop longer-term monitoring, and in January 2023 it began operating from the Kéköldi Scientific Centre in partnership with the Asociación Ambiental Kéköldi Hawkwatch. The first participants were welcomed in 2023. Milestones since include a full 2023 turtle season with a Cahuita turtle-rescue partner (40 nests protected, 1,500 hatchlings released), the 2023 Hawkwatch season (862 fieldwork hours, nearly 6 million migratory birds counted), a 2023 field season of 81 participants, 556 surveys and 366 species recorded, and a 2024 field season of 93 participants and 909 surveys with new species sighted for the reserve and an expansion of the team, activities and facilities. Ongoing work includes big-cat research, general biodiversity monitoring and building new local partnerships. Note: the canopy observation tower is currently closed pending a full rebuild, with fundraising underway.

About Kéköldi
Kéköldi (pronounced KEH-KOL-DEE) is a Bribrí Indigenous territory in the Limón province of Costa Rica, near the town of Hone Creek and the Caribbean coast around Puerto Viejo and Cahuita. The reserve encompasses over 8,500 acres (roughly 3,500 hectares) of Caribbean lowland rainforest, home to thousands of species including many of Costa Rica's flagship animals, and is recognised as one of the top three sites in the world for monitoring migratory birds of prey.
The territory sits within the traditional lands of the Bribrí, the largest of Costa Rica's eight Indigenous groups, who maintain their own language alongside Spanish and whose main economic activities include cocoa and plantain farming, with ecotourism a growing source of income. Surrounded by rapidly developing tourist destinations, Kéköldi has remained outside that wave of development because it is an Indigenous territory, and long-term biodiversity data helps make the case for its continued protection.
Volunteering in Costa Rica
Costa Rica is one of the most biodiverse countries on earth, and its Caribbean side is markedly different from the better-known Pacific coast — wetter, more forested, and home to Indigenous territories that manage their own land. Kéköldi is one of those territories.
NGO, nonprofit or charity — which is it?
People search for all of these and mean roughly the same thing. NGO — non-governmental organisation — is the term used most widely outside the UK and is what Kéköldi Rainforest Project would call itself. Nonprofit and not-for-profit describe how it is funded: no owner takes a profit. Charity is a specific legal status in the UK, and conservation organisations registered in Costa Rica are governed by Costa Rican law rather than by the Charity Commission, so the word does not map across exactly. On this site, "local NGO" means an organisation that is registered, staffed and directed in the country it works in.

What NGOs are there in Costa Rica?
The NGO in the Impact Network in Costa Rica is Kéköldi Rainforest Project, an independent conservation organisation working in the Talamanca region of Limón Province, on the Caribbean coast. It is one of eight NGOs in the network, and the network is deliberately small — every organisation in it is locally run rather than a field office of an international charity.
Are there NGOs in Kéköldi?
Yes — Kéköldi Rainforest Project works in the Talamanca region of Limón Province, on the Caribbean coast. Its work is rainforest and wildlife monitoring.
What volunteer work can I do in Costa Rica?
Rainforest and wildlife monitoring. Rainforest and wildlife monitoring, run by and with the Indigenous community whose reserve it is. Volunteers support the survey work that records what lives in the forest and how those populations change over time.
How long can I volunteer in Costa Rica for?
Placements run to fixed start dates set by the project, so the dates are published in advance rather than chosen by you.
Is this a local NGO or a volunteer agency?
Kéköldi Rainforest Project is an independent, locally run organisation. The Impact Network Foundation does not operate it, staff it or direct its work — the Foundation exists to connect volunteers to organisations like it and to publish what they achieve.
How do I apply to volunteer in Costa Rica?
Apply on the Kéköldi Rainforest Project page on this site. Every applicant then has a short one-to-one call before a place is confirmed, so you can ask anything and the organisation can check the placement is a good fit.
