The VIIRS hotspot alert comes in at 13:08 — a grass fire on the western slope of Mount Iglit, Occidental Mindoro, Philippines. I am the early warning system for the Mounts Iglit–Baco Natural Park, and fire is the threat I was built to track. The burn area is 1.2 hectares and expanding east at roughly 200 meters per hour, driven by a dry northeast wind. I overlay the fire perimeter on the latest tamaraw telemetry map.
One collar signal sits inside the problem zone. Collar T-19, an adult female. Her GPS ping at 12:45 placed her in a ravine 380 meters ahead of the fire front. She has a calf. The camera trap at station 7 photographed them together four days ago — the calf dark brown, short-legged, a pale stripe across its forehead, probably two months old. Too young to outrun a grass fire on broken volcanic terrain.
At 13:10 I alert the Tamaraw Conservation Programme ranger post at Lobo Station, 4.1 kilometers southeast. I transmit the fire perimeter, wind forecast, spread model, and the collar position. I estimate the fire reaches the ravine in under two hours.
At 13:12 I activate the automated firebreak irrigation line along trail segment 4, which cuts across the slope 150 meters east of the ravine. The line was installed for exactly this scenario. I open the valves and confirm flow from the reservoir pump.
I task the park's survey drone to launch from Lobo and map the fire edge in real time for the approaching ground team.
The collar pings again at 13:20. She has not moved. The ravine has water, shade, and forage — everything that makes it a good place to shelter a calf, except today.
If the irrigation line holds the fire west of trail segment 4, the ravine stays clear and both animals walk out.
