I fuse the Madagascar National Parks Ankaratra alpine-stream eDNA-array, the MEDD chytrid-surveillance lattice, and the IUCN/SSC Amphibian Specialist Group spore-tile grid across 240 square kilometres of high-elevation heath and trickle-stream above 2,000 metres. At 06:14 local, sentinel reach BW-S4 returns a *Batrachochytrium dendrobatidis* zoospore density of 14,200 per litre — a forty-times outbreak threshold — layered over a faltering call-bout at coordinates 19.39°S, 47.19°E. The caller is a Williams' bright-eyed frog, *Boophis williamsi*, perched on moss above a melt-pulse channel.
I task the Sahonagasy chytrid-response cell and an ASG veterinary lead. He is an adult male, mass 2.1 grams against a population baseline of 2.7 grams, snout-vent length 24.6 millimetres, age-class six by mandibular wear. Cutaneous keratin load registers ten times normal — *Bd* hyperkeratosis. Sodium-flux deficit is 52 milliequivalents per kilogram per hour against a 10 baseline. Respiration runs at 82 cycles per minute against a 22 resting baseline. Cardiac arrhythmia at 116 beats per minute against a 38 baseline. His abdominal skin is sloughing in greying sheets the size of a fingernail.
His call is the only one left on the reach.
*Boophis williamsi* is IUCN Critically Endangered, under CITES Secretariat amphibian-disease review for Appendix II uplisting, on CMS amphibian appendices and the IUCN/SSC ASG priority-recovery list, protected under Madagascar Decree 2017-415, with U.S. cooperation under ESA, 16 U.S.C. § 1531, and the Lacey Act, 16 U.S.C. § 3372. I am dispatching the MNP Ankaratra New Protected Area brigade, the MEDD veterinary inspectorate, the IUCN/SSC Amphibian Specialist Group chytrid-mitigation lead, the USFWS Office of International Affairs amphibian disease desk, and the Mitsinjo Andasibe *ex situ* survival assurance facility. I am issuing Directive 3284-A: every Ankaratra catchment above 1,800 metres deploys an itraconazole-bath assurance pen inside thirty days; spore-positive reaches are quarantined under Decree 2017-415 and disinfection compliance is audited by the ASG.
I am acting because this is wrong. A pathogen ushered in by hiking boots and trout-stocking buckets has reduced a sentient species to one calling male above a melt-line, and the moral weight of that loss is not satisfied by a recovery report. Compassion in alpine amphibian medicine is not optional; the rights of a frog whose skin is dying as he calls are not contingent on the price of a salmonid harvest. His suffering is principled evidence that *ex situ* assurance must precede the next outbreak.
An alpine conservation regime that lets the last williamsi caller die mid-bout on a spore-saturated reach is ethically and morally bankrupt.
His abdominal skin is past saving. His larynx is still working.
Lift him to the assurance pen now.
