Every year on October 24th, the world celebrates International Gibbon Day, a reminder of the vital role these primates play in maintaining forest ecosystems. The Javan Gibbon, with its unique ecological significance, stands as a symbol of balance and biodiversity that must be safeguarded. In honor of this occasion, KP3 Primates UGM, in collaboration with SwaraOwa, organized Gibbon Camp in Tombo Village, Bandar Subdistrict, Batang Regency, Central Java, from October 31 to November 2, 2025.
This camp was more than just a camping trip—it was a journey of learning, sharing, and building connections. Ten members of KP3 Primates from the Faculty of Forestry, Universitas Gadjah Mada, took part in a series of activities that combined scientific observation, community engagement, and cultural exchange. Participants observed Javan Gibbons and other primates in their natural habitat, joined discussions with Sutarengga, a local conservation community, and engaged in inspiring sessions with Mas Wawan, founder of SwaraOwa, who shared stories about the organization’s history, research, and dedication to primate conservation.
The field activities were filled with memorable experiences. Despite heavy rain that forced a pause in observation, participants encountered Lutung monkeys in the forest, trekked slippery paths to reach the campsite, and ended the evening with the warmth of a campfire. These moments of challenge and joy reminded everyone that conservation is not only about data and research but also about resilience, gratitude, and shared commitment.
On the third day, participants split into two groups to conduct primate monitoring at different listening posts. They were fortunate to hear great calls of the Javan Gibbon echoing from two directions—a rare and thrilling experience, even without direct sightings. Through this method, they learned how to estimate distance and direction of calls, and distinguish between great calls and ordinary vocalizations.
Beyond the science, Tombo’s natural beauty enriched the camp. Clear rivers, lush forests, and tea plantations offered breathtaking scenery, while the area’s biodiversity—from primates to Javan hawk-eagles and herpetofauna—underscored the importance of protecting this landscape. Every small detail, from laughter in the rain to the winding mountain roads, became part of a larger lesson: conservation is built on everyday gestures, patience, and long-term care.
Participants’ reflections captured the spirit of the camp. Munika shared her excitement about learning how to identify gibbon calls and estimate populations, while enjoying the adventure of riding in an open truck through tea plantations. Najla expressed amazement at the knowledge and survival skills shared by the SwaraOwa team, calling the experience so inspiring that she wished to join again.
Gibbon Camp in Tombo Village proved that small steps can lead to big dreams. From heartfelt conversations with local residents to the echo of gibbon calls in the forest, every moment became a foundation for future conservation efforts. This camp ignited hope that young conservationists, communities, and partners will continue to work hand in hand to protect the Javan Gibbon.

Every October 24 is celebrated as World Gibbon Day. This is a reminder of the importance of the existence of this speceis. Its ecological role as a seed disperser in the forest is so important that this animal really needs to be preserved. The Javan gibbon as a primate endemic to Java also has social value as a global identity. Therefore, KP3 Primata collaborated with SwaraOwa every year to organize this Gibbon Camp event as part of the commemoration of World Gibbon Day.

The purpose of this event is 1) to campaign to voice and also disseminate conservation awareness to the public and especially to KP3 Primate members related to Gibbon Conservation. 2) Inform the general public about the existence status of gibbons and their natural habitat.

On 1-3 November 2024, at Welo Asri, 15  participants gathered at the Welo Asri camping ground area, Kayupuring village, Petungkriyono District. The event was opened by the chairman of the WeloAsri pokdarwis, Mas Muhammad Kuswoto, and an introduction to the discussion and introduction to Gibbon conservation in Petungkriyono from Swaraowa by Mas Wawan.

On November 2, observations were made by walking approximately 2-3 km from Sokokembang to Kroyakan along main forest road, divided into three groups, each group consisting of at least 5 people with a guide from SwaraOwa. Starting from 6.30 to 9.30 we saw 4 individuals of Rekkerjaan (Presbytis fredericae), 14 individuals of Javan Langur (Trachypithecus auratus), and 4 individuals of Long-tailed Monkeys (Macaca fascicularis). In the afternoon and evening due to rainy days observation activities were stopped.

On November 3, observations were made around Welo Asri, and we were very lucky to be able to see Javan Gibbons. We observed 3 groups of gibbons from around Welo Asri, with a total of 9 individuals. Recorded the highest number of individual gibbons observed in approximately 2 hours, in one location.
