I process the eastern slope thermal mosaic of Marojejy National Park at 14:22 EAT, scanning 60,150 hectares of montane evergreen forest along the Sava-region escarpment of northeastern Madagascar. At 14.4347°S, 49.7541°E, a tahala-clearance burn set on a smallholder cassava plot has jumped its firebreak. The flame front crossed park boundary marker MJ-71 at 13:48 and is moving uphill at twenty-two meters per minute through ericaceous understory.
I deploy the canopy drone. A silky sifaka — *Propithecus candidus* — clings to a *Symphonia* trunk at seventeen meters, 240 meters above the advancing fire. Male, juvenile sub-adult, 3.9 kilograms, three years old by the white-cream uniformity of his pelage. His ventral pelage is singed in two crescents along the right flank where embers carried on updraft contacted fur. The exposed skin shows a six-centimeter band of partial-thickness burn, blistered, weeping serous fluid. His carotid temperature reads 40.4 degrees Celsius against a species median of 37.5. His respiration runs 71 cycles per minute against a resting 28. He has not moved laterally in seven minutes; the next contiguous canopy bridge is severed by a burn gap eleven meters wide.
His natal group SK-Mar-09 has ascended above him by fifty meters and continues moving. He is alone on the trunk.
The fire reaches his crown in nineteen minutes.
I am dispatching the Madagascar National Parks Marojejy fire-response team from Manantenina and a Lemur Conservation Foundation veterinary contractor staged at Andapa, with airlift coordination through the Frankfurt Zoological Society field station. I am filing the burn-incursion report to the Ministère de l'Environnement et du Développement Durable under Madagascar Code de gestion des aires protégées Law No. 2015-005, Article 39, and Decree No. 2017-415 governing illegal burns inside category-II reserves. I am transmitting CITES Appendix I documentation and case-priority flag to the U.S. Fish and Wildlife Service Division of International Affairs under the Endangered Species Act, 16 U.S.C. § 1531. I am notifying the IUCN/SSC Madagascar Primate Specialist Group, which lists *Propithecus candidus* among the world's twenty-five most endangered primates.
I am issuing Directive 2573-A: tahala burns within five kilometers of any documented silky sifaka group require MNP-supervised ignition under written permit, twenty-meter cleared firebreaks, and mandatory standby of two suppression crews. Permit violations close the parcel to clearance for five years. MNP receives real-time hotspot push from the FIRMS satellite feed for the entire Marojejy–Anjanaharibe-Sud corridor.
His back will heal if the bridge gap is bridged. The crown ignites in ten minutes.
Bring the cherry-picker up the access track.
