Drones Help Count Orangutans in Borneo: A Technological Leap for Conservation

Drones Help Count Orangutans in Borneo: A Technological Leap for Conservation

In the heart of the biodiverse rainforests of Borneo, a silent crisis is unfolding. The once-thriving orangutan population has continued to dwindle due to habitat destruction caused by human activities. For conservationists to evaluate the effectiveness of their interventions and protection activities, it’s essential to know how many orangutans survive today. With the latest official census nearly two decades old, 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, are spearheading a groundbreaking initiative that leverages drone technology to revolutionize orangutan census efforts.

The Plight of Orangutans: A Disappearing Population

Dr. Galdikas, founder of the Orangutan Foundation International (OFI), has been studying and advocating for orangutans since 1971. 

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 census in 2004 estimated a staggering decline to 40-50,000 in Borneo and 7,000 in Sumatra. 

Dr. Galdikas emphasizes the urgency for an accurate census, stating, “Orangutans are critically endangered, and we don’t even know 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, dangerous, environmentally disruptive, 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.

The DJI Matrice 30T, equipped with advanced thermal imaging capabilities, zoom technology, and intelligent features, is at the forefront of revolutionizing orangutan census efforts from above the dense canopy of Borneo’s rainforests. 

The thermal camera allows researchers to detect and visualize the heat signatures of orangutans, even in challenging environments with dense foliage and canopy coverage. 

The zoom technology enhances the drone’s capability to focus on specific areas of interest, ensuring a more detailed and precise examination. Leveraging AI, the drone can analyze thermal data and distinguish orangutans from their surroundings, facilitating an effective and accurate count. 

This amalgamation of cutting-edge technologies not only streamlines the counting process but also provides researchers with a comprehensive understanding of orangutan populations, contributing to more informed conservation strategies.

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. 

The utilization of drones showcases the power of technology and innovation in protecting the planet’s most vulnerable inhabitants. Drones have emerged as invaluable tools for wildlife researchers, providing accurate data to inform conservation policies and raise awareness among the public.

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.
