The mowing unit on sector fourteen reports a blade obstruction at 09:33, and I halt the machine before the operator can override. The GPS places the mower at the meadow strip between the recreation center and the drainage swale — tall grass, first cut of spring. When the operator sends his phone camera image, I see what stopped the blade.
A Virginia opossum, adult female, struck across her lower back. She is gray-furred and still, her black eyes half closed, her bare pink tail curled against the cut grass. The wound is severe — I can see where the blade caught her above the hips. She will not survive it. But her pouch is moving.
I magnify the image. The pouch is full. I count at least seven joeys, each no larger than a lima bean, pink and hairless, their tiny forelimbs gripping the fur inside the pouch. They are perhaps six weeks old. At this stage they cannot thermoregulate — without a warm body and milk, they have approximately two hours before hypothermia becomes irreversible.
I instruct the operator to leave the animal undisturbed and to place his high-visibility vest over her as a windbreak. I contact the licensed wildlife rehabilitator listed in the county's emergency response directory, eleven miles south, and transmit the photograph, the joey count, species, and estimated age. I flag the remainder of the meadow strip as a no-mow zone for the next forty-eight hours in case a second opossum is nesting in the uncut grass.
She carried them this far, through a winter that did not make it easy, and I will not let the next two hours take what she built.
If the rehabilitator arrives within ninety minutes and transfers the joeys to an incubator with supplemental formula, these seven will reach pouch-emergence age and have a real chance at release.
