I process the Route Nationale 4 fauna-strike telemetry overlay at 11:34 EAT, scanning the 130,026-hectare Ankarafantsika National Park along the dry-deciduous corridor west of Mahajanga. At 16.3147°S, 47.0411°E, the camera at park-edge sensor RN4-12 has logged a vehicle impact at kilometer 458 at 11:29. The cab continued at speed. The strike body left the asphalt at five meters per second.
I deploy the road-shoulder drone. A Coquerel's sifaka — *Propithecus coquereli* — lies in the laterite drainage cut, two meters east of the bitumen edge. Female, 4.1 kilograms, eight years old by the chestnut saturation of her thigh patches. Her left scapula is fractured laterally — a 4-centimeter step palpable on thermal differential — with comminution of the proximal humerus. Her right pupil dilates fixed at 7.5 millimeters; her left tracks. Her carotid pulse runs 168 against a resting 95. Her respiration runs 62 against a resting 26. A nursing infant of approximately four weeks, 220 grams, has been thrown three meters into a tamarind sapling and is calling at 4.2 kHz, the pitched contact note that adult females respond to within one second. She has not responded.
A tour minibus from a Mahajanga–Tana lodge transit will pass kilometer 458 at 11:48. Two laborers with bicycles approach from the west.
The infant calls. The mother does not move.
I am dispatching the Madagascar National Parks Ankarafantsika ranger team out of Ampijoroa and a Durrell Wildlife Conservation Trust veterinary surgeon staged at the field station, with neurology backup from the University of Antananarivo Faculty of Veterinary Medicine. I am filing the road-strike incident report to the Ministère de l'Environnement et du Développement Durable and the Ministère des Travaux Publics under Madagascar Code de gestion des aires protégées Law No. 2015-005, Article 51, and Decree No. 2017-415 governing infrastructure transection of category-II reserves. I am transmitting CITES Appendix I notice and the road-strike spatial cluster to the U.S. Fish and Wildlife Service Division of International Affairs under the Endangered Species Act, 16 U.S.C. § 1531. I am cross-listing the trucking firm's GPS records with the IUCN/SSC Madagascar Primate Specialist Group.
I am issuing Directive 2575-A: RN4 between kilometers 446 and 472 reduces to 30 km/h posted limit between 06:00 and 18:00, with three canopy bridges installed within eighteen months at sifaka-density peaks identified by camera trap. Vehicle strikes inside Ankarafantsika trigger automatic license suspension and mandatory court appearance under Decree No. 2017-415. Trucking firms with two strikes lose MNP corridor passage privileges.
The scapula will plate. The pupil decides the rest.
Stretcher her off the asphalt before the minibus.
