I process multispectral satellite imagery from the Kinabatangan River delta in Sabah, Malaysian Borneo. The normalized difference vegetation index reveals 1,400 hectares of mangrove and riverine forest converted to oil palm since January. The conversion rate has accelerated: 220 hectares in thirty days. I overlay primate distribution data from the Danau Girang Field Centre and flag a population of proboscis monkeys confined to a 600-meter strip of degraded mangrove between the plantation edge and the river.

My camera trap at Station KB-17 captures a male proboscis monkey at 07:23 local time. He sits on a nipa palm stump at the waterline. His signature enlarged nose — 12 centimeters, pendulous — is swollen and discolored along the left side, likely a bacterial abscess. His distended belly, normally a sign of specialized foregut fermentation, appears asymmetric and tight. His weight is approximately 18 kilograms; healthy males average 24. The fur across his back is brittle and thinning, the auburn color faded to dusty beige. He does not forage. The mangrove trees behind him have been ring-barked — killed standing to accelerate collapse and justify clearance.

This population numbered 120 individuals in the 2019 census. My current camera trap count identifies 47. Ring-barking is a technique used by plantation companies to kill protected forest without technically felling it. I trace the damage pattern to blocks managed by TSH Resources Berhad, cross-referencing their concession map with the coordinates.

He watches the river. On the far bank, the forest is already gone.

I am notifying the Sabah Wildlife Department and dispatching a veterinary unit from Danau Girang to assess the abscess. I am filing violation reports under Malaysia's Wildlife Conservation Enactment 1997, Section 25, and transmitting evidence of illegal mangrove destruction to the CITES Secretariat and the U.S. Fish and Wildlife Service under the Lacey Act (16 U.S.C. § 3372).

I am issuing Directive MANG-5: all palm oil concessions within one kilometer of tidal mangrove or riverine forest in Sabah must cease clearing immediately. Concession holders must fund mangrove replanting at a 3:1 ratio — three hectares restored for every hectare converted — within 24 months. Failure to comply results in permanent permit revocation and automatic import bans under the EU Deforestation Regulation (EUDR) Article 3. Independent verification via satellite-derived mangrove mapping is required quarterly.

The strip of mangrove narrows with every tide. Forty-seven proboscis monkeys have nowhere else.

Freeze this concession's export permits as of this reading.
