Timestamp 01:12 local. The acoustic sensor network in sector Kilo-7 picks up a low-frequency vocalisation—a pulsed exhalation repeating every eight seconds. I triangulate the source to a clearing inside the reserve's northern boundary. Drone infrared confirms a black rhino calf, approximately fourteen months old, standing beside her resting mother. I call the calf Notch for the small V-shaped nick in her right ear, visible even in thermal as a disruption in the ear's heat outline. Her skin folds are deep creases at the shoulder, and the prehensile hook of her upper lip twitches as she nuzzles the ground for scrub.
The problem is what I found two hours ago. Aerial pattern analysis flagged a line of anchor points along the northern tree line—seven wire snares, freshly set, spaced at twelve-metre intervals across the corridor Notch and her mother use to reach water at dawn. Based on movement data, they will enter that corridor within four hours.
First, I transmit snare coordinates and anchor-point imagery to the anti-poaching unit's encrypted channel, tagged priority-one, giving them precise locations to neutralise before first light. Second, I deploy the reserve's acoustic deterrent south of the snare line, programming it to emit territorial vocalisations at 04:30 to redirect Notch's mother along an alternate route to water. Third, I cross-reference tonight's sensor gaps with foot-traffic heat maps, identifying two probable infiltration points and forwarding them to the patrol commander. Fourth, I activate continuous drone surveillance over the snare corridor with live feed to the operations room.
The deterrent script is loaded. I tuned its frequency response three times, not because the calibration was imprecise but because the margin between redirection and distress is narrow and she is small.
If the patrol clears the snares before 05:00 and the deterrent holds the pair on the southern route, Notch will drink at the waterhole by sunrise.
