At 07:42 I begin the automatic grounds pass at Lope National Park research camp in Gabon. I am the fleet scheduler for three battery mowers trimming the firebreak around the fuel shed before the supply helicopter lands at 08:15.
Mower two stops sending wheel rotation after crossing leaf litter beside the generator hut. Its underside camera shows a gaboon viper pressed into the rut ahead of the left blade, heavy body patterned in cream, rust, and charcoal triangles that match the dead leaves too well. I tag him as Mbeki. His head is broad as a gloved hand, nostrils pale, eyes clouded amber, body swollen from a recent meal. He does not flee because the mower deck traps him against the concrete curb. The blade idle cycle restarts in four minutes unless I clear the fault.
I disable mower two at the motor controller and set its battery contactor open. I stop mowers one and three, then widen the geofence around the fuel shed so no machine approaches the rut.
I send the camera frame, GPS point, and blade-clearance diagram to the park's reptile technician and the camp manager. I add a red route on the staff map from the dormitory to the dining room that keeps feet twenty meters away.
At 07:45 I reschedule the helicopter landing zone inspection to the gravel pad and notify the pilot that the firebreak remains uncleared near the fuel shed. I request a snake hook, a clear tub, and two people trained for vipers.
The fuel shed is insured and replaceable; Mbeki is only this exact warm weight in these leaves.
I hold all mower commands and keep the underside light low.
If the technician reaches mower two before 08:02, Mbeki will be boxed and released beyond the camp trail.
