In the heart of the biodiverse rainforests of Borneo, a unique and beautiful primate can only rarely be seen. The once lush tropical rainforest which covered the entire island of Borneo would have not too long ago been inhabited by orangutans throughout. Now as these forests have made way for inevitable human development, populations have declined from that of the pre-modern era. Much is being done to save and protect forests and orangutans however, for conservationists and government to evaluate the effectiveness of their interventions and protection activities, it’s essential to know how many orangutans survive today. With an official census extremely difficult due to the sheer area and difficulties with access, the need for an accurate method to count orangutans in the rainforest has never been more critical.

Dr. Biruté Mary Galdikas, renowned for her lifelong dedication to orangutan research, and her PhD student Ruth Linsky, along with the Tanjung Puting National Park Service and Partner University Antakusuma, are spearheading a groundbreaking initiative that leverages drone technology to revolutionize orangutan census efforts.

Orangutans, our closest mammalian relatives sharing 97% of our genes, face a dire situation as their habitats are rapidly vanishing due to deforestation and fragmentation.

The Need for an Accurate Orangutan Census

A century ago, Borneo was home to approximately 230,000 orangutans. However, the last official Population Assessment in 2016 estimated 50-60,000 in Borneo and 14,200 in Sumatra.

Dr. Galdikas emphasizes the urgency for an accurate census, stating, "Orangutans are critically endangered, and we don’t even know exactly how many are left. We need an accurate census, so we can determine if all of our other activities are effective or not."

Challenges of Traditional Orangutan Census

Traditional methods of orangutan census involve manually counting nests left by orangutans as they traverse the rainforest. To count nests, field researchers trek through the forest, looking up through thick foliage for signs of an orangutan nest. Because orangutans make a new nest every night, the total number of nests in a given area of rainforest can be used to extrapolate the orangutan population.

This approach, however, is plagued by several challenges, including being time-consuming, tedious, expensive, environmentally disruptive, can be fraught with human error and differing estimates, and ultimately, inaccurate.

Drones: The Game-Changer in Orangutan Census

Enter modern drone technology, particularly the DJI Matrice 30T thermal drone. This innovative approach allows researchers to detect and count orangutans directly, offering a myriad of advantages such as improved accuracy, faster results, reduced costs, lesser environmental impact, and safer conditions for researchers.

Potential Implications of the Project

If successful, this project has the potential to revolutionize not only orangutan counting methods but also to serve as a model for efficient counting solutions for other endangered species.

This groundbreaking initiative highlights the role of drones in transforming the way researchers count and protect endangered species. By embracing technological advancements, this project sets the stage for a more efficient and accurate wildlife census, starting with the orangutans of Borneo. The potential impact is profound, offering hope for the survival of endangered species and underlining the crucial role that innovation plays in conservation efforts.
