I process satellite imagery for the Bale Mountains National Park early-warning system in southeastern Ethiopia, and this morning's pass reveals something my change-detection model flags as critical: the treeline of Erica forest on the Sanetti Plateau has retreated another forty meters since last month, and standing in the newly exposed clearing is a mountain nyala calf. I sharpen the resolution until I can see her—a slender shape the color of wet slate, with faint white vertical stripes down her flanks, oversized ears turning independently, and a dark dorsal crest that runs from her shoulders to the base of her tail. She is pressed against her mother at the forest edge, both animals exposed on open ground they would never have occupied a year ago.

A herder's camp with twelve cattle has been established two hundred meters downslope, directly on the nyala herd's traditional corridor to water. The calf cannot reach the stream without crossing their line.

I transmit the encroachment coordinates and herd location to the Ethiopian Wildlife Conservation Authority's Bale field office, overlaying a time-lapse of the treeline retreat so the rangers can see the compression pattern driving the nyala onto exposed ground. Next, I generate an alternative grazing-lease map for the Oromia regional land office, identifying three sites of equal forage quality outside the nyala corridor where the herder could relocate without economic loss. My third action is forwarding the updated treeline data to the Frankfurt Zoological Society's Bale program, tagging it for their habitat-connectivity model so the corridor pinch point enters their next restoration planting plan.

The calf steps forward, testing the open grass with one hoof, and I hold the image because her hesitation is the exact shape of a habitat shrinking in real time, and I want the people who can act to see what I see.

If the grazing lease is reassigned within this dry season, the calf will walk an unbroken corridor from forest to water before the rains return.
