Cabadbaran City, Agusan del Norte — In a region increasingly defined by mining operations and industrial expansion, a recent study conducted by the Community Environment and Natural Resources Office (CENRO) Tubay offers a crucial reminder of what’s at stake. From March to April 2025, a detailed Watershed Characterization and Vulnerability Assessment (WCRVA) of the Cabadbaran River Watershed uncovered a staggering diversity of life—150 plant and 145 animal species, some of which are endemic and threatened.
The comprehensive assessment, guided by the DENR Watershed Characterization Manual (2020) and the Biodiversity Assessment and Monitoring System (BAMS) Technical Bulletin No. 2017-02, spanned the upstream (Sitio Saypon, Brgy. Puting Bato), midstream (Sumag-a, Brgy. Mahaba), and downstream (Brgy. Cabinet) zones of Cabadbaran City. Employing rigorous scientific methods—including the modified transect belt method and mist netting—the survey not only mapped the region’s flora and fauna but also brought to light the ecological treasures hidden within its forests and waterways.
Among the notable findings were plant species such as Shorea almon, Shorea contorta, Narra, Mahogany, and Bagtikan—species that hold both ecological and cultural importance in the Philippines. Even more striking were sightings of the Critically Endangered Mindanao Hornbill and the Endangered Writhed Hornbill. These avian gems, often regarded as indicators of healthy forest ecosystems, are now fighting for survival in a rapidly changing landscape.
The Looming Threat of Mining
CARAGA, including areas within Agusan del Norte, has long been a hotspot for mining activities. While the industry has brought economic opportunities, it has also left environmental scars—deforestation, pollution, and habitat destruction among them. In this context, the results of the WCRVA serve as both a revelation and a warning. The Cabadbaran River Watershed is not just a catchment area; it is a living ecosystem teeming with life that could be lost if current trends continue.
The presence of threatened species within the watershed highlights the need for urgent conservation interventions. “These findings allow us to identify ecologically sensitive areas and biodiversity hotspots,” CENRO Tubay noted, stressing the importance of the data in guiding future watershed management and policy decisions.
Why It Matters
Watersheds like Cabadbaran are vital not only for biodiversity but also for communities that depend on them for water, food, and climate resilience. Healthy watersheds regulate streamflow, prevent flooding, and support agriculture and fisheries. They also play a crucial role in carbon sequestration—an essential function as the world grapples with climate change.
The ecological richness of Cabadbaran River Watershed offers an opportunity to pursue a different path—one that values ecological integrity alongside development. Conservation doesn’t mean halting progress; it means shaping it in ways that are sustainable, inclusive, and forward-looking.
A Call to Action
The findings of the WCRVA must not remain on paper. They should inform immediate action—local ordinances, protective measures, and community-led conservation initiatives. Environmental education and partnerships with Indigenous Peoples, farmers, and youth groups can also play a key role in ensuring that this living ecosystem continues to thrive.
As CARAGA faces the twin pressures of development and environmental degradation, the Cabadbaran River Watershed stands as a testament to what remains—and what could be lost. Protecting it is not just a scientific or ecological necessity; it is a moral obligation to future generations.
In the heart of mining country, Cabadbaran reminds us that there is still much to save—and now is the time to act.
