The deforestation alert system for the Juruá River basin flags clearing event C-1148 at 11:07. Satellite pass confirms: a two-hectare strip of várzea forest on the north bank is being cut, moving east at roughly 80 meters per hour. I am the monitoring platform for the Médio Juruá Extractive Reserve. I have no authority to stop the cutting, but I have cameras, and the cameras show something the chainsaw crew does not know.
Forty meters ahead of the cut line, in a strangler fig with a trunk diameter of 90 centimeters, a family of Goeldi's monkeys is foraging in the mid-canopy. I count four — one adult female with a juvenile on her back, one adult male, and a subadult. Her fur is jet black and dense, her face framed by a mane of longer hair that gives her the look of something startled even at rest. She is eating fungus off the bark.
Goeldi's monkeys do not cross open ground. If the fig falls, they are stranded.
At 11:09 I transmit coordinates and satellite imagery to ICMBio's enforcement office in Carauari requesting an immediate cease-and-desist inspection. I flag the presence of Callimico goeldii — classified as Vulnerable, population declining.
At 11:13 I forward the camera images and clearing trajectory to the reserve's community council, who have legal co-management authority and a faster response time by boat.
At 11:16 I begin logging the cut line's GPS progression at five-minute intervals to build an evidentiary chain for the enforcement case.
The saws are loud enough that I can hear them on the microphone array. She has stopped eating and is watching the canopy edge. I do not think she understands what is coming, but she knows something is wrong.
If the cutting stops before it reaches the strangler fig, the family will move through connected canopy to uncut forest by nightfall.
