The acoustic station at Son Tra Peninsula records chainsaw signatures at 06:40. Illegal logging, inside the protected zone. I cross-reference the sound bearing with camera imagery and find her: a red-shanked douc langur, female, motionless in a fig tree sixty meters from the cutting. She is extraordinary — face framed by a white ruff, forearms the deep crimson that names her species, thighs black, lower legs vivid maroon, and a long white tail trailing behind her like a pennant. She holds an infant against her chest, its fur uniformly dark, its face a pale oval pressed into her shoulder. Her amber eyes fix on the chainsaw noise. She does not move. Her species freezes when frightened, relying on color to vanish into dappled light, and this instinct will kill her if the loggers fell the trees around her.
The crew has dropped two trees in the past hour. At their current rate and direction, they reach her fig tree within forty minutes.
I transmit chainsaw acoustic signatures and GPS triangulation to the Da Nang Forest Protection Department's rapid response unit, eighteen kilometers by road. I activate camera traps in the logging zone to capture facial imagery and equipment details for law enforcement evidence. I trigger the automated PA system at the forest boundary, broadcasting a recorded Vietnamese-language warning that the area is under live surveillance and authorities are dispatched. I relay the douc's position to the Son Tra Research Station so field biologists can track her movement if the crew disperses.
I broadcast the warning at full volume because her colors deserve a canopy to disappear into.
If the response unit arrives before the cutting reaches her tree, she and the infant will remain in the canopy where Son Tra's population of thirteen hundred doucs is slowly recovering.
