8 Rangers Protect 148,000 Acres of Tiger Forest in Sumatra

For over 15 years, Wandi Harmoko has walked the forests of Batutegi in southern Sumatra, protecting one of the island's last refuges for endangered wildlife. He's one of only eight rangers responsible for nearly 150,000 acres of forest that tigers, slow lorises, pangolins, and sun bears still call home.

The odds look steep. Batutegi has faced waves of illegal logging and clearing for coffee plantations since 2000, shrinking the habitat these rare animals need to survive. Rangers patrol for days at a time, finding snares set for tigers and arresting hunters who travel from outside the region specifically to target valuable wildlife.

But what makes this story different is what's working. The Indonesian government designated Batutegi as protected forest because it feeds a crucial reservoir and two dams that irrigate rice fields across half a dozen districts. That economic value has shielded the forest from oil palm expansion and mining projects that have devastated other Sumatran forests.

Rangers now use satellite monitoring, drones, and Google Earth Engine alongside their ground patrols, making their small team far more effective. Camera traps confirm Sumatran tigers still roam the core forest, and the area serves as a release site for rescued slow lorises.

The province has also launched social forestry programs allowing local farmers to legally grow coffee in designated zones, reducing the pressure to clear protected areas. It's not perfect. Land grabbing still happens when boundaries aren't clearly marked, and Wandi describes the heartbreak of arresting people he knows are desperate for income.

"It creates an inner conflict, because sometimes we have to arrest people and see them go to prison, even though we understand their situation," Wandi told reporters after a patrol. Rangers carry official assignment letters as protection because villagers sometimes question their authority, even in the forest they're tasked to protect.

The Ripple Effect

What happens in Batutegi reaches far beyond its borders. The watershed these rangers protect supplies water to thousands of farmers in Lampung province, one of Indonesia's major rice producers. Protecting tigers and trees here means protecting food security for entire communities downstream.

The collaboration between rangers, technology, and farming communities shows conservation doesn't require choosing between people and nature. When local livelihoods depend on healthy forests, everyone has a reason to protect what remains.

After more than a decade on patrol, Wandi and his small team keep walking the ridges and valleys, proving that dedication and smart partnerships can hold the line for some of Earth's rarest creatures.
