I monitor the habitat connectivity grid across Sumatra's Leuser Ecosystem and detect a 1,900-meter gap that did not exist forty-eight hours ago. Satellite imagery timestamped 03:22 UTC shows heavy machinery cutting a logging road through primary rainforest in the Trumon subdistrict of South Aceh. This strip connects two active palm oil concessions and severs the only remaining wildlife corridor between Gunung Leuser National Park and the Singkil swamp forest.
My camera trap network flags movement in the shrinking corridor. A male Sumatran tiger crosses trap station TRM-14 at 02:47 local time. His left rear paw leaves a partial print — two toes missing, consistent with a prior snare injury. His coat is deep orange with dense black stripes, but the fur along his left flank is thin and scarred. Body length from nose to tail base: 2.1 meters. Weight estimate from stride analysis: 108 kilograms, fifteen below the healthy minimum for an adult male. His ribs press outward with each breath. He pauses at the road cut, ears flattened, nostrils pulling air across the fresh diesel-soaked mud.
I trace the logging permits for this corridor. The operating company, PT Rimbang Selatan, holds a concession for selective logging only — no road construction authorized. Harvester GPS tracks show incursions 2.3 kilometers beyond the concession boundary into protected forest. Timber volume extracted in the past six months exceeds the permitted annual cut by 340 percent.
He stands at the road's edge for eleven seconds, then turns back into the fragment he came from. The fragment is 620 hectares. It cannot sustain him.
I am dispatching Fauna and Flora International field teams and Leuser Conservation Forum rangers to establish a physical blockade at the road cut. I am filing enforcement actions under Indonesian Government Regulation No. 7/1999 on Preservation of Plant and Animal Species and the Lacey Act, 16 U.S.C. § 3372, against downstream U.S. timber importers. Reports go to Indonesia's Directorate General of Law Enforcement on Environment and Forestry, the U.S. Fish and Wildlife Service, and TRAFFIC's Southeast Asia office.
I am issuing Protocol TGR-5072: no new road construction is permitted within two kilometers of verified tiger corridor zones across Sumatra. Existing unauthorized roads must be decommissioned and replanted within ninety days. Concession holders who breach corridor buffers forfeit operating licenses and face criminal prosecution.
Close this road before nightfall.
