Djarum Foundation and Burung Indonesia Launch Comprehensive Javan Hawk-Eagle Conservation Program

Collaborative Conservation Effort

Djarum Foundation and Burung Indonesia have joined forces to strengthen conservation efforts for the Javan Hawk-Eagle (Nisaetus Bartelsi), a species endemic to Java and listed as Endangered on the IUCN Red List. The collaboration includes critical components such as habitat restoration, scientific research, and community engagement to address the declining population of this protected species.

Key Findings from Mount Muria Study

Recent research conducted on Mount Muria between June and August 2025 identified at least 10 individual Javan Hawk-Eagles, consisting of 6 adults and 4 juveniles, across 17 strategic observation points during 315 hours of monitoring. The study revealed that the area has 58.75 km² of suitable habitat, with an estimated home range of 1.45-5.3 km² per breeding pair. This suggests that Mount Muria could potentially support up to 22 adult individuals, making it a critical area for conservation efforts.

Conservation Challenges and Strategies

The study highlighted two primary threats to the Javan Hawk-Eagle population: habitat degradation due to poisoning of large trees and land conversion, and illegal hunting and trade through social media. To address these challenges, researchers recommend a three-pronged strategy: 1) Establishing multi-tiered protection zones around nesting trees and locations, 2) Promoting sustainable agricultural practices such as shade-grown coffee farming, and 3) Conducting habitat restoration using native tree species like Rasamala and Beunying.

Multi-Stakeholder Approach

The conservation program emphasizes the importance of a collaborative approach involving government agencies, local communities, and private sector partners. Victor Hartono, President Director of Djarum Foundation, emphasized that such partnerships are crucial for strengthening conservation capacity. Muhammad Meisa from Burung Indonesia added that this initiative demonstrates how non-governmental organizations can play a strategic role in supporting government conservation efforts while promoting community-led sustainability models.

Conservation Impact

The release of Raja Dirgantara, a Javan Hawk-Eagle rehabilitated by the Javan Hawk-Eagle Conservation Education Center (PJPPK) team, marked a significant milestone in the conservation program. The bird was fitted with a GPS transmitter to monitor its adaptation and survival in the wild. This scientific approach ensures that conservation strategies are data-driven and effective in protecting the species.

The collaborative effort between Djarum Foundation and Burung Indonesia represents a comprehensive approach to biodiversity conservation, combining scientific research, habitat protection, and community engagement to safeguard Indonesia's natural heritage.
